A strong camper trailer tire matches your trailer’s required size and load capacity, with radial or bias construction suited to how you tow. The Free Country Grand Ride Set 4 is a compelling starting point for buyers needing ST225/75R15 radial tires rated at 2,830 pounds each. This lineup also includes heavy-duty all-steel radials, lower-capacity bias tires, and ready-to-install tire-and-wheel assemblies.
Those differences matter: a tire’s maximum load rating does not establish that it fits your rim or meets your trailer’s requirements. Check the size and load information on your existing tires and trailer placard before choosing.
The rankings emphasize camper-relevant fit, useful specifications, and included components, while noting where product data leaves a compatibility question unresolved.
The Free Country Grand Ride Set 4 leads this roundup for buyers whose camper calls for ST225/75R15 tires. It is a radial set of four with a listed 2,830-pound load capacity per tire and Load Range E construction, plus a Scuff Guard intended to protect the sidewall and rim. Its 15-inch rim size is not a universal fit, so confirm your trailer’s tire size and required capacity before buying.
If your trailer needs another size or a mounted wheel, consider the alternatives below.

Detailed Reviews: Best Camper Trailer Tires

#1 · Best Overall
1. Free Country Grand Ride
- Size: 225/75R15 10PR
- Weight: 28.8 lb
- Load Capacity: 2830 lb
- Rim Size: 15 in
Best for: Sidewall-protection seekers.
Why it ranks #1: This radial set of four is rated at 2,830 pounds per tire in ST225/75R15, with Load Range E construction and a Scuff Guard.
The featured Scuff Guard adds protection at the tire’s sidewall and rim, giving trailer owners a practical defense against scuffing in those exposed areas. This four-tire set uses ST225/75R15 sizing and 10-ply Load Range E construction, with a listed 2,830-pound load capacity for each tire.
The Scuff Guard is specifically described as adding sidewall and rim protection, which can help address contact wear in those areas. The 10-ply Load Range E rating and 2,830-pound capacity give buyers concrete load specifications to compare with their trailer requirements. Since this is a set of four tires rather than a wheel-and-tire assembly, it suits owners replacing tires while retaining compatible existing rims; the 15-inch rim size is the stated wheel fit.
- Scuff Guard adds sidewall and rim protection
- Four tires included
- 10-ply Load Range E construction
- Listed capacity of 2,830 pounds per tire
- Tires are supplied without rims.
Skip it if you need wheel-and-tire assemblies ready to mount; this set contains tires only and leaves rim selection to you.
For trailer owners replacing all four tires who want the stated Scuff Guard sidewall protection, this set is worth considering. Check that ST225/75R15 and the listed load capacity suit your trailer and existing rims.

#2 · Full Set Upgrade
2. Free Country HD Trailer Tires
- Size: Set of 4
- Weight: 49.2 lb
- Load Capacity: 2400 lb
- Rim Size: 15 in
Best for: Heavy-load tire-only replacements.
Why it ranks #2: The four ST205/75R15 radial tires have Load Range E and a 2,400-pound capacity, plus a full-width nylon cap ply and Scuff Guard.
A full nylon cap ply overlay across the tread area is the defining feature of these Free Country tires, extending beyond the shoulder-only strips described for many alternatives. The four ST205/75R15 tires are 10-ply Load Range E, with a stated 2,400-pound capacity and a Scuff Guard sidewall ring.
The full-tread nylon cap ply overlay is presented as a safety-related construction upgrade, giving buyers a specific feature to weigh when choosing trailer tires. A Scuff Guard ring adds sidewall protection, while the 10-ply Load Range E rating and 2,400-pound capacity offer load specifications for matching a trailer. This is a tire-only set, so it fits a replacement workflow using compatible existing 15-inch rims rather than providing complete wheel assemblies.
- Full nylon cap ply overlay across tread
- Scuff Guard sidewall ring
- Four tires in the set
- 10-ply Load Range E, 2,400-pound capacity
- Rims are not included.
Skip it if you need wheels included with your replacement tires; these are tire-only, so you must use compatible existing rims or source them separately.
Consider this four-tire set when replacing compatible ST205/75R15 trailer tires and prioritizing the listed tread overlay and sidewall ring. Its 2,400-pound capacity is a key selection boundary, and rims must be supplied separately.

3. Libra All Steel ST235
- Size: 235/80R16-16PR
- Weight: 200 lb
- Load Capacity: 4190 lb
- Rim Size: 16 in
Best for: Heavy RV tire replacements.
Why it ranks #3: This 16-ply, Load Range H radial set lists a 4,190-pound capacity per tire, making it suited to heavy RVs when the size matches.
All-steel construction paired with a 16-ply Load Range H rating distinguishes this four-tire set for large, heavy RVs and trailers. Each ST235/80R16 tire has a listed 4,190-pound capacity, providing a substantial stated load figure for owners evaluating replacements for regular tires in this size.
The all-steel construction and 16-ply Load Range H rating are the central specifications for buyers comparing tires for heavy RV or trailer use. The stated 4,190-pound capacity per tire offers a concrete figure to assess against the trailer’s requirements. With four tires supplied in ST235/80R16 size, the set supports a multi-tire replacement, but the tires are intended for trailer use only and do not include rims.
- All-steel construction
- 16-ply Load Range H
- Four tires included
- Listed capacity of 4,190 pounds per tire
- Rims are not included.
Skip it if you need complete wheel assemblies; this set supplies trailer tires only, leaving compatible 16-inch rims to be provided separately.
For owners replacing four ST235/80R16 trailer tires on a heavy RV or trailer, the all-steel construction and stated capacity are key considerations. Confirm the load requirements and plan to reuse or source compatible rims.

#4 · Radial Set of Four
4. Transeagle Radial II
- Size: 205/75R14
- Weight: 88 lb
- Load Capacity: 2039 lb
- Rim Size: 14 in
Best for: Fourteen-inch radial tire buyers.
Why it ranks #4: The set includes four ST205/75R14 radial tires with an 8-ply rating and listed 2,039-pound load capacity per tire.
Four ST205/75R14 radial tires in one set offer a tire-only replacement option for compatible trailer wheels. The 8-ply Load Range D specification and listed 2,039-pound load capacity give buyers concrete construction and capacity figures to compare with their trailer requirements before selecting replacements.
The radial ST205/75R14 size identifies the tire format and diameter category for checking against a trailer’s existing setup, while the 14-inch rim specification adds a wheel-size reference. An 8-ply Load Range D rating and 2,039-pound capacity provide useful load information for planning a replacement. Since the included components are tires only, owners can keep compatible rims but must handle mounting on those wheels separately; this set provides four tires for a multi-wheel change.
- Four radial tires included
- ST205/75R14 size
- 8-ply Load Range D
- Listed load capacity of 2,039 pounds
- Tires are supplied without rims.
Skip it if you need mounted tire-and-wheel assemblies; this four-tire set includes tires only and requires compatible rims for installation.
For trailer owners replacing four compatible ST205/75R14 tires who want the listed radial and Load Range D specifications, this set merits consideration. Check capacity against trailer needs and plan to provide rims separately.

5. Garvee ST205/75D14
- Size: ST205/75D14
- Weight: 70.6 lb
- Rim Size: 14 in
Best for: Fourteen-inch wheel replacements.
Why it ranks #5: This two-tire Load Range C package includes 14-inch rims and is explicitly described for family camping trailers; verify its bias-ply size suits your trailer.
Included 14-by-6-inch steel rims make this Garvee two-pack a tire-and-wheel assembly rather than a tire-only replacement, simplifying the parts needed for a wheel change. Its ST205/75D14 tires use 6-ply Load Range C construction and are rated for up to 1,760 pounds at 50 PSI.
The included rims have a 5-lug, 4.5-inch bolt pattern, giving buyers specific fit details to check against their trailer before installation. Because the tires arrive with rims, the assembly avoids sourcing wheels separately for a compatible setup. The 6-ply Load Range C rating and stated 1,760-pound capacity at 50 PSI provide useful load and inflation reference points for utility, boat, and family camping trailer applications.
- Two tire-and-rim assemblies included
- 14-by-6-inch steel rims
- 5-lug, 4.5-inch bolt pattern
- Rated up to 1,760 pounds at 50 PSI
- The two-piece set does not provide a complete four-wheel replacement.
Skip it if you need four assemblies in one purchase; this pack contains two, so plan for another pair before replacing every wheel.
Choose this pair if your utility, boat, or camping trailer takes ST205/75D14 tires and the listed 5-lug pattern. Its included rims simplify replacement, but the two-assembly pack is not a four-wheel set.

6. GarveeTech ST205/75D15
- Size: ST205/75D15
- Weight: 75 lb
- Rim Size: 15 in
Best for: Fifteen-inch wheel assemblies.
Why it ranks #6: The two ST205/75D15 bias-ply tires arrive on 15-inch wheels and are listed for camper and travel trailers, with 1,820-pound capacity each.
Pre-mounted ST205/75D15 bias-ply tires on white 15-inch spoke wheels let buyers replace tire and wheel together in one assembly. The set of two uses 6-ply Load Range C construction, with a maximum load of 1,820 pounds at 50 PSI and a 5-lug, 4.5-inch PCD.
The included 15-inch wheels and stated 5-lug, 4.5-inch PCD give a trailer owner concrete mounting details to compare before installation. Pre-mounted assemblies can simplify a replacement workflow by combining the tire and wheel in each unit. Nylon cord layers and double steel belts are listed construction features associated with towing stability and durability; the 1,820-pound maximum load at 50 PSI helps buyers assess suitability against their trailer’s requirements.
- Two pre-mounted tire-and-wheel assemblies
- 15-inch white spoke wheels
- 5-lug, 4.5-inch PCD
- Nylon cord layers and double steel belts
- The tires use bias-ply construction rather than radial construction.
Skip it if you specifically require radial tires; these ST205/75D15 assemblies are listed as bias ply, so choose a radial option instead.
This pair suits buyers replacing compatible 15-inch trailer wheels who value pre-mounted assemblies and the listed reinforced construction. Verify the 5-lug, 4.5-inch PCD and load needs; the tires are bias ply.

7. eCustomRim ST205/75D15
- Size: Set of 2
- Weight: 72 lb
- Rim Size: 15 in
Best for: White-wheel two-pack buyers.
Why it ranks #7: This two-tire bias-ply assembly includes 15-by-5-inch rims with a 5-lug, 4.5-inch bolt pattern and a listed 1,820-pound tire capacity.
The included white 15-by-5-inch rims give this eCustomRim two-pack a ready wheel-and-tire format for compatible trailer setups. Each ST205/75D15 bias-ply tire is rated for a maximum load of 1,820 pounds at 50 PSI, and the rim is specified with a 5-lug, 4.5-inch bolt pattern.
The 5-lug, 4.5-inch bolt pattern and 3.19-inch center bore provide specific mounting details to compare with a trailer’s wheel requirements. With tires already paired to 15-by-5-inch rims, buyers can replace compatible assemblies without sourcing wheels separately. The 27.2-inch overall diameter and stated 1,820-pound maximum load at 50 PSI help with size and capacity checks; the bias-ply construction is an important consideration when choosing tire type.
- Two tire-and-rim assemblies
- White 15-by-5-inch rims
- 5-lug, 4.5-inch bolt pattern
- 3.19-inch center bore
- The tires are bias ply, not radial.
Skip it if you require radial trailer tires; this ST205/75D15 set is specified as bias ply, so select a radial tire type instead.
This set is for buyers needing two compatible ST205/75D15 assemblies with specified mounting dimensions and white rims. Compare the center bore, bolt pattern, and load rating with your trailer; these tires use bias-ply construction.

- Size: 205/75D15 Pack of 2
- Weight: 39.2 lb
- Load Capacity: 1.82E+3 lb
- Rim Size: 15 in
Best for: Deep-tread tire-only pairs.
Why it ranks #8: These two ST205/75D15 bias tires have Load Range C, a 1,820-pound capacity each, and are described as having deeper tread.
A deeper tread is the key stated feature of this Free Country pair, described as supporting longer tire life. The ST205/75D15 bias tires use 6-ply Load Range C construction and are rated for up to 1,820 pounds at 50 PSI, giving trailer owners specific capacity and inflation figures to assess.
The deeper tread is explicitly associated with longer life, a useful consideration for owners comparing tire-only replacements. The 6-ply Load Range C rating and 1,820-pound maximum load at 50 PSI provide concrete operating specifications for checking against trailer needs. These two bias-ply tires are listed for a 5.5-inch rim width, but rims are not included, so the set fits a replacement workflow that uses compatible wheels already on hand.
- Deeper tread described as supporting longer life
- Two ST205/75D15 tires
- 6-ply Load Range C construction
- Maximum load of 1,820 pounds at 50 PSI
- Rims are not included.
Skip it if you need wheel-and-tire assemblies in one package; these are two tires only and require compatible 15-inch rims separately.
This pair suits trailer owners seeking deeper-tread ST205/75D15 bias tires for compatible existing wheels. Use the stated 5.5-inch rim width and load figures when checking fit and capacity; no rims are supplied.

9. Garvee ST175/80D13
- Size: ST175/80D13
- Weight: 57.3 lb
- Rim Size: 15 in
Best for: Compact trailer wheel assemblies.
Why it ranks #9: This two-tire Load Range C package includes 13-inch wheels and lists 1,360 pounds per tire; the smaller size limits it to compatible trailers.
Black 13-inch spoke wheels are included with these Garvee ST175/80D13 tire assemblies, making the pair a combined tire-and-wheel replacement option. The 6-ply Load Range C tires are rated for up to 1,360 pounds at 50 PSI, and the listed wheel pattern is five lugs on 4.5 inches.
Because each tire comes with a steel spoke wheel, buyers can replace compatible assemblies without sourcing rims separately. The five-lug, 4.5-inch bolt pattern provides a specific mounting reference for checking a trailer’s hub setup. A 6-ply Load Range C rating and maximum 1,360-pound load at 50 PSI help buyers evaluate capacity for utility, boat, or family camping trailer use. The package contains two assemblies, not four.
- Two tire-and-wheel assemblies included
- Black steel spoke wheels
- 5-lug, 4.5-inch bolt pattern
- 6-ply Load Range C construction
- The two-piece pack is not a full four-wheel replacement.
Skip it if you need to replace four wheels at once; this pack contains two assemblies, so another pair is needed for a complete set.
Choose this pair for a compatible trailer using ST175/80D13 tires when included black wheels simplify replacement. Check the five-lug pattern and 1,360-pound capacity against your setup; two assemblies cover only two wheels.

- Size: ST175/80D13
- Weight: 55.1 lb
- Rim Size: 13 in
Best for: Thirteen-inch pre-mounted pairs.
Why it ranks #10: The two bias-ply tires are listed for camper and travel trailers and include 13-inch wheels, but their 1,360-pound capacity is the lineup’s lowest.
Pre-mounted ST175/80D13 bias tires on white 13-inch spoke wheels combine tire and wheel replacement in this two-piece set. Each 6-ply Load Range C tire has a maximum load of 1,360 pounds at 50 PSI, and the wheels use a 5-lug, 4.5-inch PCD.
The included 13-inch wheels and specified 5-lug, 4.5-inch PCD give buyers concrete details for checking hub compatibility before installation. Pre-mounted assemblies simplify the replacement process by supplying tire and wheel together. Nylon cord layers and double steel belts are listed construction features associated with towing stability and durability, while the load and inflation figures help assess trailer demands. The set is for buyers replacing two compatible assemblies, not a full four-wheel set.
- Two pre-mounted assemblies
- 13-inch white spoke wheels
- 5-lug, 4.5-inch PCD
- Nylon cord layers and double steel belts
- The tires use bias-ply construction.
Skip it if you require radial tires; these ST175/80D13 assemblies are listed as bias ply, so select a radial option for that requirement.
This pair fits buyers seeking pre-mounted ST175/80D13 assemblies for compatible utility, boat, camper, or travel trailers. Check the 5-lug pattern and load needs; the listed tires are bias ply and the pack contains two.

View on AmazonAvoid a tire-size and wheel-fit mismatch
A tire that carries enough weight can still be the wrong fit if its size or wheel pattern does not match your trailer. These listings illustrate why the full designation matters: ST205/75D15 and ST205/75R15 share the nominal size but specify different construction, while ST175/80D13 and ST235/80R16 represent substantially different sizes. Mounted assemblies add another compatibility check.
Garvee ST205/75D14 lists a 5-lug, 4.5-inch bolt pattern, and the GarveeTech ST205/75D15 assembly also lists a 5-lug, 4.5-inch pattern; do not assume that makes either wheel compatible with your hubs. Compare the existing tire sidewall and trailer placard, then verify rim diameter, wheel width, bolt pattern, and clearance.
Product data can identify listed dimensions, but it does not confirm fit on a particular trailer. If replacing tires only, remember that the wheel is not included with several tire-only options.
Why matching load capacity matters
Under-rated tires can be overloaded when the trailer’s actual weight exceeds their combined capacity, so compare the trailer’s requirements with the rating of each tire. The products range from 1,360 pounds per tire on the ST175/80D13 assemblies to 4,190 pounds on the 16-ply Libra All Steel ST235. That spread is not a reason to choose the highest number automatically: the larger ST235/80R16 size and Load Range H may not fit a trailer designed for a smaller tire.
Capacity figures also describe individual tires, not necessarily the safe carrying capacity of the whole trailer; axle limits and load distribution matter. Use the trailer placard and manufacturer guidance to establish the required size and load rating, and do not exceed the rating printed on the tire.
Match the tire to the trailer before comparing features such as Scuff Guard or included rims.
How to Choose Camper Trailer Tires
Size and rim fit
Start with the complete tire size and confirm it matches your trailer’s specified fitment. This group ranges from ST175/80D13 and ST205/75D14 to ST205/75R15 and ST235/80R16; listed rim sizes run from 13 to 16 inches. The letter in the size also varies: several products are bias-ply D-designated tires, while the Free Country and Transeagle options use R-designated radial sizes.
Wheel assemblies add a bolt-pattern check, with some listing a 5-lug, 4.5-inch pattern. Smaller trailers may need the 13-inch options, while larger trailers may call for a different size, but neither should be assumed from trailer type alone.
Follow the size on the trailer placard or current tire and confirm wheel fitment separately.
Load capacity and construction
Choose a tire whose rating meets the trailer maker’s load requirement at the specified pressure, rather than selecting by ply count alone. Listed capacity ranges from 1,360 pounds on the ST175/80D13 options to 4,190 pounds on the 16-ply ST235/80R16 Libra set. Several Load Range C tires list 1,820 pounds, while the ST205/75R15 Free Country HD is Load Range E at 2,400 pounds and the Grand Ride is rated at 2,830 pounds.
The high-capacity Libra option may suit a heavy RV only if its size is correct. Lighter-duty compatible trailers may favor a lower-rated option, but only when its capacity satisfies the trailer’s requirements.
The listings do not replace the trailer’s axle and tire specifications.
Tire-only or mounted assembly
Decide whether you need tires alone or a tire-and-wheel assembly, and check that the wheel dimensions fit before ordering. The Grand Ride and Free Country HD sets are tires only, and the Libra all-steel set also excludes rims. Garvee, GarveeTech, and eCustomRim list mounted assemblies with two tires; their wheel sizes range from 13 to 15 inches.
Assemblies can be convenient when replacing compatible wheels as well as tires, while tire-only sets may be appropriate when reusing existing wheels. Buyers who need a full set should also compare package quantity: some listings provide two tires and others provide four.
Verify the package contents, bolt pattern, rim size, and trailer fit before treating a mounted set as ready for your specific camper.
Which Camper Trailer Tires Should You Choose?
For a trailer specified for ST225/75R15 tires and a higher load rating, choose the Free Country Grand Ride; its four radial tires list 2,830 pounds per tire and Load Range E. If your trailer instead calls for ST205/75R15 and you want four tires, the Free Country HD Trailer Tires offer Load Range E, a 2,400-pound capacity, and Scuff Guard. Heavy RV owners whose required fitment is ST235/80R16 can consider the Libra All Steel ST235, rated at 4,190 pounds per tire.
For a compatible trailer needing wheels as well as tires, compare the Garvee ST205/75D14 or GarveeTech ST205/75D15 assemblies and check the bolt pattern. Smaller ST175/80D13 trailers can look at either Garvee option, but confirm the trailer’s required capacity.
In every case, use the trailer placard and axle guidance to verify size and load rating.

Frequently Asked Questions
How do I check the correct tire size and load rating for my camper trailer?
Start with the trailer’s tire placard and axle guidance, then match the tire size and required load rating before buying. Confirm whether the listing is for tires alone or includes wheels, and check the wheel fitment where applicable. For example, the roundup’s leading set fits ST225/75R15; that size is not universal.
Should I choose radial or bias-ply tires for my trailer’s towing conditions?
Choose the tire construction specified for your trailer and towing needs rather than assuming one type suits every camper. The roundup includes radial options as well as tire listings marked with D sizing; check the product details and your trailer guidance to confirm the appropriate type. Also verify size and load rating before purchase.
How often should I inspect or replace camper trailer tires, including the spare?
Inspect every tire, including the spare, before trips and periodically during use. Check inflation against the trailer or tire guidance, and look for visible damage, unusual wear, or other changes that warrant professional assessment. Replace tires when their condition or guidance indicates they should not be used; the supplied product details do not establish a universal interval.
What should I check when buying a tire-and-wheel assembly?
Confirm that both the tire size and wheel fit your trailer, including the bolt pattern where the listing provides one. The Garvee ST205/75D14 assembly lists a 5-lug, 4.5-inch bolt pattern, while other assemblies have different stated sizes. Verify compatibility with your trailer before choosing an assembly.
How do I choose between the tire options if my trailer needs a different size?
Use the placard and axle guidance to identify the required size and capacity first. The roundup includes options for ST205/75R15, ST235/80R16, ST205/75D14, ST205/75D15, and ST175/80D13 fitments. Compare only options that match your trailer’s requirements, and confirm the required load rating rather than relying on size alone.
Final Words
For a trailer specified for ST225/75R15 tires, the Free Country Grand Ride Set 4 is the roundup’s lead choice, with four radial tires and a listed 2,830-pound capacity per tire. If your trailer needs another size, consider the alternatives by fitment and whether you need wheels included. Before ordering, verify tire size, required load rating, axle guidance, and any wheel bolt-pattern requirements.
