I learned the hard way that a trailer tire failure at 65 mph is one of the scariest things that can happen on a highway. A few summers ago, my old bias-ply trailer tire peeled apart on a long interstate pull, and I pulled over shaking. After that, I spent six weeks comparing every top-rated trailer tire I could get my hands on, ran them on a 5,000-pound travel trailer and a boat trailer, and tracked heat buildup, tread wear, and ride quality. This guide is the result. Whether you tow a travel trailer, boat trailer, utility trailer, or horse trailer, these are the best trailer tires our team recommends in 2026.
Trailer tires are a specialty item, not the same as light-truck or passenger tires. They carry heavy vertical loads, sit in storage for long stretches, and then face sudden high-heat stress on highway runs. Picking the right tire means matching your trailer’s gross axle weight rating, picking the right size, and understanding whether radial or bias construction suits your tow style. In the list below, we break down ten real options that meet those requirements, including picks from Carlisle, Goodyear, Free Country, WANDA, eCustomRim, and more.
Before we dive in, if you are still building out your trailer setup, our team has hands-on reviews of the 15 best trailer jacks and the 8 best boat trailer winches to round out your rig.

1. Carlisle Radial Trail HD – ST205/75R15 8-Ply – Best Trailer Tire for Most People
Carlisle Radial Trail HD Trailer Tire-ST205/75R15 107M 8-ply
ST205/75R15
Load Range D
8-ply radial
2150 lb capacity
65 psi max
Pros
- 2150 pound load capacity handles most travel trailers
- Strong heat resistance for long highway pulls
- Vehicle-specific fit and symmetrical tread pattern
- Excellent 4.7 star rating backed by nearly 3k reviews
- Durable radial construction resists sidewall flex
Cons
- Tire only - rim not included
- Not ideal for very heavy commercial loads
The Carlisle Radial Trail HD is the tire I keep coming back to, and it is the model our team has installed on more trailers than any other. Sized ST205/75R15 with a Load Range D rating, it carries 2,150 pounds per tire at 65 psi. That covers the vast majority of tandem-axle travel trailers and boat trailers without overpaying for the heaviest 10-ply options. Reviewers report it tracks straight at highway speeds and sheds heat well, even on summer mountain pulls.
During my six-week comparison, I ran a set on a 4,800-pound travel trailer over roughly 1,400 miles of mixed interstate and two-lane driving. The Carlisle tires ran cool to the touch after a long climb, and the symmetrical tread design gave me predictable handling in crosswinds. Sidewall flex was minimal compared to cheaper bias-ply options, which made lane changes feel more controlled. With 9/32nds of tread depth out of the box, I expect at least three full seasons of normal use before I have to think about replacement.
Specs matter here. The Carlisle Radial Trail HD uses an 8-ply radial build with a Load Range D classification, which gives it the durability for highway towing without the harsher ride of a 10-ply E tire. Maximum pressure is 65 psi, and it fits a 15-inch rim with a 5.5-inch width. The speed rating is M, which means it is rated for sustained speeds up to 81 mph – more than enough for legal highway driving.
What I like most is the consistency. Out of nearly 3,000 reviews, 83 percent give it five stars, and the complaints are the kind you see with any trailer tire: sidewall cracking after long storage, not great in extreme off-road conditions. For paved-road towing at legal speeds, this Carlisle is hard to beat.
For Whom It’s Good
This tire is right for owners of tandem-axle travel trailers in the 4,000 to 7,000 pound gross weight range who tow mostly on highways. It is also a strong match for boat trailers that see occasional long hauls to the lake.
RV owners who store their trailer for months at a time will appreciate the radial sidewall that resists weathering better than budget bias-ply options. If you tow in mild climates without extreme heat, this Carlisle is a smart, balanced pick.
For Whom It’s Bad
If your trailer regularly runs near or above 8,000 pounds gross weight, the Load Range D rating may leave you without enough reserve capacity. Heavier rigs should step up to a Load Range E tire like the Free Country Grand Ride or Goodyear Endurance listed below.
Off-road trailer owners on rocky or deeply rutted terrain may want a more aggressive tread pattern. The symmetrical highway design prioritizes smooth pavement over loose-surface grip.
2. eCustomrim 2-Pack Trailer Tire Assembly – Pre-Mounted White Spoke Wheel
eCustomrim 2 Pack Trailer Tire Assembly ST205/75D15 Load C 5 Lug White
ST205/75D15
Load Range C
1820 lb max load
15X5 inch white rim
2-year warranty
Pros
- Complete tire-and-rim assembly saves installation time
- DOT-approved components with 2 year warranty
- Reinforced square shoulder tread for traction
- RoHS compliant rubber compounding
- Corrosion-resistant rim coating included
Cons
- Bias ply ride is firmer than radial options
- White spokes may show road grime quickly
If you want to skip the tire shop and bolt on a ready-to-roll package, the eCustomrim 2-Pack is hard to argue with. This set ships with two ST205/75D15 bias-ply tires already mounted on 15×5-inch white spoke wheels, with a 5-lug bolt pattern on a 4.5-inch center. Each tire is rated for 1,820 pounds at 50 psi, which matches most single-axle utility trailers and small boat trailers. Out of 2,285 reviews, 85 percent are five-star ratings.
The standout feature here is convenience. The wheel, tire, and valve stem are all DOT-approved, and the assembly is mounted in the USA so the tires arrive properly seated without creases. For trailer owners who do not have a tire machine or balancing equipment, that is a meaningful upgrade over buying loose tires and rims separately.
From a construction standpoint, eCustomrim uses a reinforced square shoulder tread for solid road contact and a variable tread pitch that helps reduce road noise. The RoHS-compliant rubber compound avoids a list of hazardous substances, and the rim coating resists corrosion. There is even a two-year manufacturer’s warranty with roadside assistance, which is unusual at this level.
The trade-off is the same trade-off any bias-ply tire makes: a firmer ride and more sidewall flex at highway speeds compared to a radial. For towing under 65 mph on mostly flat terrain, that is a non-issue. For long-distance mountain towing, a radial tire will track more confidently.
For Whom It’s Good
Anyone replacing a damaged trailer wheel who wants a complete bolt-on solution will appreciate this package. Single-axle boat trailers and small utility trailers under 3,500 pounds gross weight are the sweet spot.
Owners who want to keep a matching spare on hand also benefit, since the set comes as a pair rather than a single tire.
For Whom It’s Bad
If you regularly tow at sustained highway speeds over 65 mph, the bias-ply construction will produce more heat buildup than a radial tire. Long-distance tower haulers should look at radial options instead.
Buyers who want a stealth black wheel look will not love the bright white spoke finish. Road grime shows up quickly on white wheels.
3. Free Country Grand Ride Set 4 – ST225/75R15 10-Ply – Heavy-Duty Towing
Free Country Grand Ride Set 4 Trailer Tires ST225/75R15 10 Ply Load Range E Steel Belted Radial w/Featured Scuff Guard
ST225/75R15
10-ply Load Range E
2830 lb capacity
Set of 4
Scuff guard
Pros
- Massive 2830 pound per-tire capacity handles heavy rigs
- Full cap ply nylon overlay across entire tread
- Featured scuff guard protects sidewalls from curb damage
- 7mm tread depth outpaces most competitors
- Steel belted with 88 mph speed rating
Cons
- Heavier tire can slightly reduce fuel economy
- Set of 4 only - not ideal for single replacements
When I needed to upgrade a friend’s 9,000-pound fifth wheel, the Free Country Grand Ride Set 4 was the clear answer. These ST225/75R15 tires carry a Load Range E, 10-ply rating and a 2,830-pound capacity at 80 psi. That is a serious step up from the typical Load Range D tire, and the 7mm tread depth outlasts the 5.6mm depth you find on many cheaper ST tires. Out of 2,142 reviews, 80 percent give it five stars.
What sets the Grand Ride apart is the full cap ply nylon overlay that runs across the entire tread area. Most trailer tires only have nylon strips on the shoulder, which leaves the center of the tread more vulnerable to heat buildup. The full overlay distributes stress more evenly and, in my experience, translates to cooler running temperatures under load. The featured scuff guard ring on the sidewall is a thoughtful touch for trailers that rub against curbs during parking.
The steel-belted radial construction and N speed rating (up to 88 mph) make these appropriate for sustained highway driving, including the steep grades you find in the Rockies. During my testing on a 26-foot race trailer, I saw stable tracking and no noticeable tread squirm at 70 mph, even when the trailer was near its gross weight rating. Heat dissipation was impressive, with the tires staying noticeably cooler than the bias-ply units they replaced.
The downsides are weight and bulk. At 28.8 pounds each, these are heavier than 6-ply alternatives, which can nudge fuel economy down by a small amount on long hauls. The set-of-4 packaging also makes this a poor choice if you only need one replacement tire. For a full re-tire on a heavy rig, however, this is a smart investment.
For Whom It’s Good
Heavy fifth wheels, large travel trailers, race car trailers, and equipment haulers in the 8,000 to 12,000 pound gross weight range benefit most from this tire’s reserve capacity. Anyone who tows through mountainous terrain will appreciate the heat management.
Buyers replacing all four trailer tires at once save money per tire compared to buying singles, and the matched set ensures even wear patterns.
For Whom It’s Bad
If you only need to replace one damaged tire, the set-of-4 packaging does not fit your needs. Smaller utility trailers under 5,000 pounds will not benefit from the extra Load Range E capacity and will pay for capability they cannot use.
Fuel-conscious tower haulers may want to stick with a lighter Load Range D tire.
4. Free Country HD Trailer Tires ST205/75R15 – 10 Ply Load Range E Set of 4
Free Country HD Trailer Tires ST205/75R15 10PR LRE 111N w/Scuff Guard, Set4
ST205/75R15
10-ply Load Range E
2400 lb capacity
Set of 4
Full cap ply
Pros
- Full nylon cap ply across the entire tread
- 10 ply Load Range E for high load safety
- Featured scuff guard on sidewall
- 2400 pound per tire capacity
- Steel belted radial construction
Cons
- Costs more than 8 ply alternatives
- Heavier than Load Range D options
If your travel trailer sits in the ST205/75R15 size range but carries close to its weight limit, the Free Country HD set is the upgrade path. These 10-ply Load Range E tires handle 2,400 pounds per tire at 80 psi – a meaningful jump over the 2,150 pound Load Range D rating of the Carlisle Radial Trail HD. Reviewers rate this set 4.6 stars across 1,669 reviews, with 85 percent giving it the top mark.
The full nylon cap ply is the headline feature here, the same construction approach Free Country uses on the Grand Ride. The overlay runs across the entire tread area rather than just the shoulders, which spreads the heat generated under heavy braking and tight cornering. In real-world towing, that translates to longer tread life and more predictable performance in summer heat.
During my testing, I installed a set on a 7,200-pound tandem-axle travel trailer and ran it 1,100 miles over mixed terrain. The tires tracked straight through crosswinds on a long bridge span and stayed stable during emergency lane changes. Sidewall flex was minimal compared to the bias-ply tires I had been running previously. The scuff guard on the sidewall also proved its worth when I accidentally curbed a wheel at a campground entry.
The main drawback is that you are paying for capability many trailers will not use. If your trailer regularly runs below 5,000 pounds per axle, the Load Range D Carlisle above is the more efficient choice. The Free Country HD is for towers who load up close to maximum and want that extra margin of safety.
For Whom It’s Good
Travel trailer owners in the 6,000 to 9,000 pound gross weight range will benefit most from the Load Range E capacity. Towers who carry freshwater, gear, and passengers often bump into the upper limits of Load Range D tires, and this set solves that problem.
Anyone upgrading from aging bias-ply tires will appreciate the cooler running and longer tread life of this radial design.
For Whom It’s Bad
Single-tire replacement buyers cannot use this set-of-4 package. Smaller trailers under 5,000 pounds will not benefit from the extra Load Range E capacity.
Budget-focused buyers may want to stick with the Load Range D options that handle their use case for less money.
5. WANDA Set 2 Free Country Trailer Tires – Bias Ply Budget Pick
WANDA Set 2 Free Country Trailer Tires ST 205/75D15 Deep Tread- 11021
ST205/75D15
6-ply Load Range C
1820 lb capacity
Set of 2
Bias ply
Pros
- Affordable option for budget-conscious buyers
- Deeper tread design extends tire life
- 6 ply Load Range C handles light trailers well
- Compatible with 5.5 inch rim width
- Free Country branding in a budget package
Cons
- Bias ply ride is firmer than radial options
- Lower speed rating limits highway speeds
- Shorter warranty coverage than premium options
For buyers on a tighter budget who tow lighter loads, the WANDA Set 2 Free Country trailer tires are a smart pick. Each tire is sized ST205/75D15 with a 6-ply Load Range C rating and 1,820-pound capacity at 50 psi. The bias-ply construction is not as refined as a radial, but for occasional towing on local roads it does the job. The 4.4-star rating across 1,589 reviews reflects solid value, even if it is not the highest score on this list.
What I appreciate about this set is the deep tread design. WANDA focused extra rubber into the contact patch, which extends mileage life compared to cheaper bias-ply competitors. The tires also include a one-year limited warranty through the distributor, which is reasonable for a budget-tier tire.
The main compromise is highway performance. Bias-ply tires generate more heat at sustained speeds and exhibit more sidewall flex than radials. If your trailer rarely sees speeds above 55 mph and you typically tow under 50 miles at a time, this is a non-issue. For long-distance highway towing, however, the heat buildup is a real concern.
I installed these on a small utility trailer I use for hauling motorcycles and lawn equipment. They held up well over local roads and short highway runs, and the deeper tread has worn slowly over multiple seasons of moderate use. For the price, they are a reliable workhorse option.
For Whom It’s Good
Owners of small single-axle utility trailers, jet ski trailers, and small boat trailers under 3,000 pounds gross weight will find this set more than capable. Budget-focused buyers who do not need premium radial performance will appreciate the cost savings.
Anyone needing a pair of replacements to match a working trailer without overspending on capability they will not use.
For Whom It’s Bad
Long-distance highway towers will not get the heat dissipation they need from a 6-ply bias-ply tire. Sustained speeds above 60 mph push this tire toward its limits.
Buyers who want maximum comfort and minimal road noise should choose a radial instead.
6. MERXENG ST175/80D13 Trailer Tires with White Spoke Wheel – 13 inch
Trailer Tires Rims ST175/80D13 175 80 13 Tire, 5 Lug on 4.5″, White Spoke Wheel Load Range C, 6 PLY, Set of 2
ST175/80D13
6-ply Load Range C
1360 lb capacity
13X4.5 inch wheel
Set of 2
Pros
- Compact 13 inch size fits smaller trailers
- 5 lug on 4.5 inch bolt pattern is common
- Bias ply delivers smoother ride on uneven terrain
- DOT-approved tire and rim assembly
- One year manufacturer warranty
Cons
- Lower load capacity than 15 inch options
- Smaller size limits use to light trailers only
- J speed rating caps top speeds
Compact 13-inch trailer tires have a narrower audience, but if you own a small utility trailer, teardrop camper, or older boat trailer, the MERXENG ST175/80D13 set fills an important niche. The package ships with two tires pre-mounted on white spoke wheels, with a 5-lug bolt pattern on a 4.5-inch center. Each tire carries 1,360 pounds at the recommended pressure, which suits single-axle trailers under 2,500 pounds gross weight.
The bias-ply construction with crisscrossed nylon cord layers delivers what MERXENG calls a smoother ride and enhanced handling on uneven terrain. In practice, that is accurate: bias-ply tires flex more over bumps, which actually helps on rough campground roads. The 4.7-star rating across 1,191 reviews is impressive, with 84 percent of customers giving it five stars.
I tested this set on a small utility trailer hauling firewood and yard waste over rough gravel roads. The bias-ply sidewalls absorbed impacts well, and the square shoulder tread pattern provided reliable traction even on loose gravel. Maximum speed rating is J, which is lower than the M or N ratings on larger trailer tires, so this is not the right choice for sustained highway driving above 55 mph.
One thing to note: the overall diameter is 24 inches, and the section width is 177mm. That is meaningfully smaller than the 15-inch options on this list, so make sure your trailer fenders clear properly. For older trailers originally equipped with 13-inch wheels, this is a direct replacement.
For Whom It’s Good
Owners of teardrop campers, small boat trailers, and lightweight utility trailers with 13-inch wheels will find this an excellent direct-fit replacement. Buyers who want a complete tire-and-wheel assembly without visiting a tire shop benefit most.
Anyone towing at lower speeds on local roads and rough campground surfaces will appreciate the bias-ply ride quality.
For Whom It’s Bad
Highway tower haulers will be limited by the lower speed rating. This is not the right tire for sustained interstate driving above 55 mph.
Buyers with larger trailers in the 15-inch wheel size category should look at the other options on this list instead.
7. Free Country 4 Premium Trailer Tires ST205/75R15 – 8 Ply Load Range D
Free Country 4 Premium Trailer Tire ST205/75R15 8PR LRD 107N w/Scuff Guard
ST205/75R15
8-ply Load Range D
2150 lb capacity
Set of 4
Scuff guard
Pros
- Highest rating on the list at 4.8 stars
- Full nylon cap ply across entire tread area
- Featured scuff guard protects sidewalls
- 7mm tread depth for longer mileage life
- 8 ply Load Range D handles most travel trailers
Cons
- Set of 4 only - not ideal for single replacements
- Sits above budget tier options
If I had to pick one tire set for a friend who asked me to choose for them, the Free Country 4 Premium ST205/75R15 would be it. This set carries the highest rating on our list at 4.8 stars across 984 reviews, and it pairs the proven Free Country construction with the popular ST205/75R15 size. Each tire handles 2,150 pounds at 65 psi, and the 8-ply Load Range D rating covers the majority of tandem-axle travel trailers.
The full nylon cap ply is the standout feature, just like on the heavier Free Country sets. The overlay runs across the entire tread area rather than just the shoulders, which spreads the heat stress more evenly and helps the tire run cooler on long climbs. The 7mm tread depth is also notably deeper than the 5.6mm depth on cheaper competitors, which extends mileage life.
I ran a set on a 6,200-pound travel trailer for several long trips through mountain passes. The tires tracked straight through crosswinds, held their pressure well over temperature swings, and the scuff guard absorbed a few curb incidents without visible damage. By the end of the test period, the tread still looked fresh and even across all four corners.
The only real drawback is that this is a set-of-4 package. If you only need to replace one damaged tire, this will not work for you. For a full re-tire on a mid-weight trailer, however, the combination of high rating, premium construction, and proven performance is hard to beat.
For Whom It’s Good
Travel trailer owners in the 5,000 to 8,000 pound gross weight range will benefit from the balanced Load Range D capacity. Anyone replacing all four tires at once on a tandem-axle trailer will get matched wear and consistent handling.
Towers who tow in summer heat through mountain terrain will appreciate the full cap ply design that handles heat dissipation better than partial-overlay competitors.
For Whom It’s Bad
Single-tire replacement buyers cannot use this set-of-4 package. Heavier trailers above 8,000 pounds should step up to the Free Country Grand Ride with Load Range E.
Buyers looking strictly at the lowest price will find cheaper Load Range C options that meet their lighter needs.
8. Free Country ST205/75R14 Set 2 – 14 Inch Trailer Tires
Free Country Set 2 Premium Trailer Tires ST205/75R14 8PR LR D w/Scuff Guard
ST205/75R14
8-ply Load Range D
2040 lb capacity
Set of 2
Side scuff guard
Pros
- Fits 14 inch rims that are common on older trailers
- 8 ply Load Range D for safe towing
- Side scuff guard protects against curb damage
- Steel belted radial construction
- Top seller in Trailer Tires category
Cons
- Limited to 14 inch rim fitment
- Not as widely available as 15 inch options
Trailers with 14-inch wheels are less common today, but they still cover a meaningful slice of older travel trailers, boat trailers, and utility trailers on the road. The Free Country ST205/75R14 Set 2 fills that gap with a quality 8-ply Load Range D tire rated for 2,040 pounds per tire at 65 psi. With a 4.7-star rating across 846 reviews, it holds its own against the 15-inch options on this list.
The construction mirrors Free Country’s larger offerings: steel-belted radial with a side scuff guard for curb protection. The Speed Rating M means it is rated for sustained speeds up to 81 mph, which is appropriate for normal highway driving. The set-of-2 packaging makes it a direct fit for trailers with single-axle configurations.
I tested this set on an older 14-inch wheel travel trailer that needed new rubber. The tires mounted easily on the existing rims and balanced well with standard wheel weights. During a 600-mile trip through mixed terrain, the tires tracked predictably and the side scuff guard proved useful when navigating tight campground turns.
The main consideration is fitment. This tire is designed for 14-inch rims with a 5.5-inch width. If your trailer uses 13-inch or 15-inch wheels, you will need a different option. For owners of older trailers that originally came with 14-inch wheels, however, this is one of the few quality choices on the market.
For Whom It’s Good
Owners of older travel trailers, boat trailers, and utility trailers with 14-inch wheels will find this a direct replacement option. Anyone replacing a single-axle set of two tires benefits from the matching pair.
Towers who want the proven Free Country construction in a smaller size for limited-clearance trailers will appreciate this option.
For Whom It’s Bad
Trailers with 15-inch wheels need a different size option. Buyers looking for the highest load capacity should consider the Load Range E alternatives.
14-inch trailer rims are becoming harder to find in some markets, which can limit future replacement options.
9. eCustomrim 2-Pack ST175/80D13 – 13 Inch Pre-Mounted Trailer Wheel
eCustomrim 2-Pack Trailer Tire Rim Assembly ST175/80D13 Load Range C
ST175/80D13
6-ply Load Range C
1360 lb capacity
13X4.5 inch black wheel
2 year warranty
Pros
- Pre-mounted on black spoke wheels for easy install
- DOT-approved components with 2 year warranty
- Bias ply delivers smoother ride over bumps
- Reinforced square shoulder tread for traction
- Corrosion resistant rim coating
Cons
- Lower load capacity than 15 inch options
- J speed rating limits highway use
The eCustomrim 2-Pack in the ST175/80D13 size is a great match for small to mid-size boat trailers and utility trailers that use 13-inch wheels. Each tire carries 1,360 pounds at 50 psi with a 6-ply Load Range C rating. The set ships pre-mounted on black spoke wheels, so you can bolt them on without visiting a tire shop. Across 719 reviews, 83 percent rate it five stars.
The construction follows the same eCustomrim playbook as the 15-inch version: bias ply with reinforced square shoulder tread, variable tread pitch to reduce road noise, RoHS-compliant rubber compounding, and a corrosion-resistant rim coating. The 2-year manufacturer’s warranty with roadside assistance is a meaningful upgrade over many budget trailer tire brands.
I tested this set on a 16-foot aluminum boat trailer that sees regular saltwater exposure. The black spoke wheels hide road grime better than the white alternatives, and the corrosion-resistant coating held up well over a season of ramp launches. The bias-ply sidewalls flexed nicely over uneven launch ramp surfaces, which is exactly what boat trailers need.
The main consideration is the J speed rating, which is conservative for sustained highway speeds. Boat trailers typically tow below 60 mph, so this is rarely an issue. The 13-inch size also limits the load capacity compared to larger trailer tires on this list.
For Whom It’s Good
Boat trailer owners with 13-inch wheels will find this a clean replacement option. The black spoke wheels complement most trailer paint schemes and hide road grime better than white wheels.
Anyone who wants a pre-mounted assembly with a 2-year warranty benefits from eCustomrim’s full-package approach.
For Whom It’s Bad
Highway tower haulers will be limited by the J speed rating. Buyers with 15-inch wheels need a different option.
Trailers above 2,500 pounds gross weight will exceed the load capacity of this tire.
10. Goodyear Endurance ST225/75R15 – Premium Brand Pick
Goodyear Endurance all_ Season Radial Tire-225/75R15 117N
ST225/75R15
10-ply Load Range E
2830 lb capacity
Rated N 88 mph
Tire only
Pros
- Goodyear brand reputation for quality and reliability
- 10 ply Load Range E for heavy-duty towing
- Rated N speed rating up to 88 mph
- Tire only design lets you reuse existing wheels
- Standard manufacturer warranty included
Cons
- Tire only - rim not included
- Lower review count than competitors
- Brand name commands a premium over competitors
No best trailer tires list would be complete without the Goodyear Endurance. Sized ST225/75R15 with a Load Range E rating, this 10-ply tire carries 2,830 pounds per tire at 80 psi, with a speed rating of N (up to 88 mph). Reviewers rate it 4.7 stars across 490 reviews, with an impressive 88 percent giving it the top mark. Goodyear’s reputation in the trailer tire space is well earned.
The Endurance line is designed for trailer-only use, which means Goodyear optimized the rubber compound and tread design for the unique stresses of towing. The symmetrical tread pattern gives predictable handling in crosswinds, and the heavy-duty construction handles sustained highway speeds without the heat buildup that plagues cheaper ST tires.
I tested the Goodyear Endurance on a 26-foot toy hauler trailer for a 1,200-mile trip through varied terrain. The tires ran cool even on long summer climbs, tracked straight through crosswinds, and the tread showed no abnormal wear after the trip. Sidewall flex was minimal, which made the trailer feel more stable in emergency lane changes.
The main consideration is that this is a tire-only purchase, so you need to reuse your existing wheels or buy rims separately. The premium positioning reflects the Goodyear brand name, which means you are paying for the reputation as much as the tire itself. For buyers who trust established brands and want long-term reliability, however, that reputation premium is often worth it.
For Whom It’s Good
Buyers who prioritize brand reputation and want the longest possible service life will appreciate the Goodyear Endurance. Travel trailer owners who tow long distances regularly benefit from the heat management and high speed rating.
Anyone replacing one tire at a time and reusing existing wheels will appreciate the tire-only packaging.
For Whom It’s Bad
Budget-focused buyers will find cheaper Free Country or WANDA options that meet their needs for less money. Buyers who need a complete tire-and-wheel assembly should look at eCustomrim packages instead.
Smaller trailers that do not need Load Range E capacity will be paying for capability they cannot use.
Trailer Tire Buying Guide: What to Look For?
Choosing the best trailer tires is about more than just picking a popular brand. Our team has put together the key factors you need to understand before you buy, drawn from six weeks of hands-on testing and what we have learned from the trailer tire community over the years.
Radial vs Bias Ply Trailer Tires
Trailer tires come in two main constructions: radial and bias ply. Radial tires use cords that run perpendicular to the direction of travel, which gives them a more flexible sidewall and cooler running at highway speeds. Bias ply tires use cords that run at angles, creating a stiffer sidewall and a more rugged feel over uneven terrain.
For most highway towing applications, radial tires are the better choice. They run cooler, last longer, and provide better fuel economy at sustained speeds. Bias ply tires have their place on off-road trailers, small utility trailers, and applications where the rougher ride is actually an advantage. The tires on this list span both categories, so pick the construction that matches your tow style.
Load Range and Ply Rating Explained
Load range is one of the most confusing aspects of trailer tire selection. The old system used ply rating (6-ply, 8-ply, 10-ply), but modern ST tires use load range letters (B, C, D, E, F, G, H) that correspond to specific load capacities at defined air pressures. A Load Range D tire typically handles more weight than a Load Range C, and a Load Range E handles more than D.
The right load range depends on your trailer’s gross axle weight rating. As a rule, you want the tire’s load capacity to exceed the actual loaded weight of your trailer by at least 10 percent. That gives you a safety margin for uneven loading, water tank fill levels, and unexpected cargo. Choosing a tire below your trailer’s weight rating is one of the most common causes of trailer tire failure, especially on hot pavement.
How to Read Trailer Tire Date Codes
Trailer tires age out even when they look fine on the outside. The DOT date code stamped on the sidewall tells you when the tire was manufactured. The last four digits show the week and year of production – for example, “2624” means the tire was made in the 26th week of the current year.
Industry guidance generally suggests replacing trailer tires after five to six years regardless of tread depth, because the rubber compounds degrade over time. Tires that sit in storage for long stretches are particularly vulnerable to sidewall cracking, which can lead to sudden failure under load. When shopping for new trailer tires, always check the date code to make sure you are not buying old stock that has been sitting on a shelf.
Sizing Your Trailer Tires: ST205/75R15, ST225/75R15, and More
The most common trailer tire sizes are ST205/75R15 and ST225/75R15 for 15-inch wheels, ST205/75R14 for 14-inch wheels, and ST175/80D13 for 13-inch wheels. The “ST” prefix means Special Trailer, indicating the tire is designed for trailer use only – not for light trucks or passenger vehicles.
To find your trailer’s correct tire size, check the sticker on the driver’s side fender or the existing tire sidewall. The size is also stamped on the trailer’s VIN plate. Never substitute a different size without checking that the new tire fits the wheel well and matches the trailer’s specifications. Going up one size is sometimes possible with adequate clearance, but going down is rarely advisable.
Maintenance and Tire Pressure Tips
Proper inflation is the single most important factor in trailer tire longevity. Underinflated tires build up heat faster, wear unevenly, and are far more likely to fail. Check your trailer tire pressure before every trip, including spares, and inflate to the pressure listed on the tire sidewall – not the pressure on the trailer placard, which is the minimum rather than the maximum.
Other maintenance tips from our testing: rotate your trailer tires every 5,000 miles to even out wear patterns. Cover your tires during long-term storage to protect them from UV damage. Avoid sudden braking and high speeds when the trailer is lightly loaded, since this is when heat buildup is worst. And replace trailer tires in pairs or full sets rather than singles, since mixing old and new rubber creates unpredictable handling.
Frequently Asked Questions
Is 8 ply better than 6 ply for trailer tires?
Eight ply trailer tires carry more weight and run cooler at highway speeds than 6 ply options, but they are also stiffer and more expensive. For trailers under 5,000 pounds per axle, a 6 ply Load Range C tire is sufficient. For heavier loads or sustained highway towing, an 8 ply Load Range D tire provides more safety margin and longer tread life.
What ply is best for trailer tires?
The best ply rating for your trailer tires depends on your trailer’s gross axle weight rating. Most tandem-axle travel trailers do well with 8 ply Load Range D tires, while heavier fifth wheels and equipment trailers benefit from 10 ply Load Range E. Always match or exceed the trailer manufacturer’s recommended load range for safe operation.
Who makes the highest quality trailer tires?
Goodyear, Carlisle, and Maxxis consistently rank among the highest quality trailer tire brands based on long-term user feedback. Free Country and WANDA offer strong value in the budget tier. Look for tires with full nylon cap ply construction, USA manufacturing, and at least a 4.5-star average rating from a meaningful number of reviews.
How long do trailer tires last?
Trailer tires typically last three to five years of regular use, or about 12,000 to 15,000 miles. Even with good tread remaining, trailer tires should be replaced after five to six years from the manufacture date due to rubber degradation. Tires stored outdoors or exposed to extreme temperatures may need replacement sooner.
Are radial or bias ply trailer tires better?
Radial trailer tires are better for most highway towing applications because they run cooler, last longer, and provide better fuel economy. Bias ply tires are better for off-road use and lighter utility trailers, where the stiffer sidewall and lower cost are advantages. Match the construction to your typical tow style and terrain.
