A strong fifth-wheel tire choice matches the trailer’s required size and load rating, with radial construction and enough capacity for its actual loaded weight. This roundup includes a purpose-built 12-ply option for fifth-wheels, higher-capacity 16-inch tires, and several 15-inch tire-and-wheel assemblies. The products differ in size, construction, load range, and whether rims are included, so the right pick depends on your trailer’s specifications rather than a single universal winner.
Check the sidewall and owner documentation before choosing: a tire that looks close in size may still have the wrong load rating or bolt pattern. Our ranking puts fifth-wheel suitability first, then compares listed specifications and installation components to help narrow the choices.
The Omni Trail Capability STR Radial Trailer Tire leads because its listing specifically identifies 5th-wheel, RV, and heavy-cargo trailer applications, and it uses a 12-ply ST235/80R16 radial design. It is sold as two tires, with no wheel assembly stated, so confirm your trailer’s size and whether you need matching rims. For buyers prioritizing a listed load capacity, the Carlisle Radial Trail HD is a 16-inch, 12-ply tire rated at 3,960 pounds, but its listing does not specifically identify fifth-wheel use.

Detailed Reviews: Best Tires For 5Th Wheel Camper

#1 · Best Overall
1. Omni Trail Capability STR
- Size: ST235/80R16 -12PLY
- Rim Size: 16 in
Best for: Heavy fifth-wheel radial tires.
Why it ranks #1: Its listing specifically names 5th-wheel and RV use, with reinforced sidewalls, radial construction, and a 12-ply ST235/80R16 size.
A 12-ply ST235/80R16 radial construction is the defining specification of Omni Trail’s two-tire set, which is expressly listed for fifth-wheel, RV and heavy-cargo trailer applications. Reinforced sidewalls are intended to support heavy cargo and resist deflection in demanding turns, addressing stability needs for loaded trailer travel.
The reinforced radial body and robust sidewall structure are described as supporting heavy cargo and maintaining tire integrity during turns, connecting construction to the demands of full-payload transport. Specialty ST radial construction is presented for steady tracking and towing stability without passenger-tire compromises. The listing includes two ST235/80R16 tires with 12-ply construction; it does not state a load capacity or identify rims as included, so compare the tire specifications with your trailer requirements before choosing.
- Specifically listed for fifth-wheel, RV and heavy-cargo trailers
- ST235/80R16 size with 12-ply construction
- Reinforced radial body supports heavy cargo
- Sidewalls are described as resisting deflection in turns
- The supplied details do not state a tire load capacity.
Skip it if you require a stated load-capacity figure before comparing tires; the Carlisle Radial Trail HD lists 3,960 pounds.
Consider this pair if your fifth-wheel calls for ST235/80R16 tires and you value the listed reinforced sidewalls and radial construction. The supplied information does not state load capacity or include a rim specification.

#2 · Highest Capacity
2. Carlisle Radial Trail HD
- Size: ST235/85R16/12
- Rim Size: 16 in
- Weight: 43.9 lb
Best for: High-capacity 16-inch tire-only option.
Why it ranks #2: This 16-inch, 12-ply ST235/85R16 tire lists a 3,960-pound load capacity, though the listing does not specifically state fifth-wheel fit.
A listed 3,960-pound load capacity distinguishes the Carlisle Radial Trail HD, an ST235/85R16 radial trailer tire specified for a 16-inch rim. It is a tire-only product, making it relevant to fifth-wheel owners who need that size and capacity while retaining or sourcing wheels separately.
The ST235/85R16 size and 16-inch rim specification help buyers narrow fitment checks, while the listed 3,960-pound capacity gives a concrete figure to compare with trailer requirements. Carlisle identifies this as a tire, not an assembly, and the included-components field likewise lists a tire; owners therefore need a separate compatible rim for installation. Its 43.9-pound listed weight and dimensions are additional handling and storage details, though the tire size and capacity remain the primary selection checks.
- ST235/85R16 trailer tire
- Listed load capacity of 3,960 pounds
- Specified for a 16-inch rim
- Carlisle Radial Trail HD model
- Rim is not included.
Skip it if you want a complete assembly rather than a tire alone; the eCustomRim ST225/75R15 package includes tire-and-wheel assemblies.
Consider this Carlisle tire if your fifth-wheel uses ST235/85R16 tires and you need the listed 3,960-pound capacity. It is tire-only, so plan on a compatible 16-inch rim rather than expecting a wheel in the package.

#3 · Best Set of Four
3. Free Country Grand Ride
- Size: 225/75R15 10PR
- Rim Size: 15 in
- Weight: 28.8 lb
Best for: Four-wheel radial tire shoppers.
Why it ranks #3: The set of four ST225/75R15 radial tires has Load Range E construction, a listed 2,830-pound capacity, and sidewall Scuff Guard protection.
A four-tire set with Load Range E, 10-ply construction and a stated 2,830-pound load capacity per tire gives buyers a higher-rated option to assess for trailer duty. Free Country’s Scuff Guard adds protection to the sidewall and rim, a useful detail for owners considering exposed wheel edges during towing.
The ST225/75R15 size and 15-inch rim specification help narrow fitment checks, while the Load Range E, 10-ply rating and 2,830-pound capacity provide concrete load details for comparing trailer tires. Scuff Guard is described as adding sidewall and rim protection and extending tire life, making it relevant to buyers focused on wheel-area wear. This is a set of four tires; the supplied details do not identify included rims, so plan around the tire-only package description.
- Set of four ST225/75R15 tires
- Load Range E and 10-ply rating
- Listed load capacity of 2,830 pounds per tire
- Scuff Guard adds sidewall and rim protection
- Rims are not identified as included in the supplied product details.
Skip it if you want a tire-and-wheel assembly; the eCustomRim ST225/75R15 assembly includes rims and uses a six-lug pattern.
Consider this set if your trailer uses ST225/75R15 tires and you want four Load Range E tires with Scuff Guard. The supplied product details do not specify rims as included, so it suits buyers sourcing tires separately.

#4 · Best E-Rated Assembly
4. eCustomRim Radial Assembly
- Size: 225/75R15
- Rim Size: 15 in
- Weight: 94 lb
Best for: Six-lug radial assembly pair.
Why it ranks #4: Each ST225/75R15 radial is rated for 2,860 pounds at 80 PSI and Load Range E; assemblies include 6-lug rims.
A radial ST225/75R15 tire rated for Load Range E and up to 2,860 pounds per tire comes mounted on a 15-by-6-inch rim in this two-assembly set. Its six-lug, 5.5-inch pattern makes the wheel configuration a key point for fifth-wheel owners comparing replacement assemblies.
The listed 80 PSI maximum and 28.1-inch overall diameter add practical tire specifications for checking setup requirements, while the 2,860-pound maximum load and Load Range E rating support load comparisons. The rim’s 4.25-inch center bore and six-lug, 5.5-inch bolt pattern help buyers check wheel compatibility in more detail. This is a pair of radial tire-and-wheel assemblies, not a four-piece set, so it best suits pair replacement or owners sourcing the remaining assemblies separately.
- Two radial tire-and-wheel assemblies
- ST225/75R15, Load Range E tires
- Maximum load of 2,860 pounds at 80 PSI per tire
- 15-by-6-inch rim with six-lug, 5.5-inch pattern
- The two-piece set does not cover all four trailer positions.
Skip it if you need a complete four-wheel set; the Free Country Grand Ride ST225/75R15 listing includes four tires, though rims are not specified.
A fit to consider for a trailer using ST225/75R15 radial assemblies with a six-lug, 5.5-inch wheel pattern. Check the stated capacity and pressure against your requirements; this package includes two assemblies.

#5 · Best Nylon Overlay
5. Free Country HD Trailer Tires
- Size: Set of 4
- Rim Size: 15 in
- Weight: 49.2 lb
Best for: Four-tire nylon-overlay set.
Why it ranks #5: These ST205/75R15 Load Range E tires list 2,400-pound capacity and a full nylon cap-ply overlay; rims are not included.
A full-width nylon cap-ply overlay across the tread is the central distinction of these Free Country heavy-duty tires, compared with shoulder-only nylon strips described for many other products. The set of four ST205/75R15 tires pairs that construction with Load Range E and a 2,400-pound capacity per tire.
The 10-ply, Load Range E rating and stated 2,400-pound capacity give fifth-wheel owners specific load figures to compare with their trailer requirements. The nylon overlay spans the tread area, while the Scuff Guard ring is described as providing better tire-side protection; together, these features address tread construction and sidewall exposure. The package is four tires only, with 15-inch rims not included, so buyers need to plan for compatible wheels separately.
- Set of four ST205/75R15 trailer tires
- 10-ply rated, Load Range E construction
- Listed capacity of 2,400 pounds per tire
- Full-tread nylon cap ply and Scuff Guard ring
- Rims are not included.
Skip it if you need wheels in the same package; the Free Country ST205/75R15 wheel assembly includes a black mod wheel.
A fit to consider for fifth-wheel owners seeking four ST205/75R15 tires with a full-tread nylon overlay and Scuff Guard. Since rims are excluded, this set suits buyers who already have compatible 15-inch wheels.

6. Free Country Trailer Tire Wheel
- Size: ST205/75R15 /5×4.5
- Rim Size: 15 in
Best for: Black mod-wheel replacement pair.
Why it ranks #6: The ST205/75R15 radial tire and wheel assembly is 8-ply, Load Range D, and uses a 5×4.5-inch bolt pattern.
A black mod wheel is paired with each ST205/75R15 trailer tire in this two-piece Free Country assembly set. The title specifies 8-ply, Load Range D and 107N, giving shoppers more than a size alone when comparing replacement wheels and tires for a trailer with a matching 5-by-4.5-inch pattern.
The ST205/75R15 size and 5-by-4.5-inch pattern help focus compatibility checks on the tire and wheel dimensions, while the 8-ply, Load Range D and 107N markings provide additional listed tire specifications. Because the product is identified as a tire-wheel assembly, it offers a paired component rather than a tire-only listing. The package is a pair, so owners planning to replace all four trailer positions will need to account for the two-assembly quantity.
- Two trailer tire-wheel assemblies
- ST205/75R15 tire size
- 8-ply, Load Range D and 107N listed
- Black mod wheels with a 5-by-4.5-inch pattern
- The supplied listing does not state a load-capacity figure.
Skip it if you need a listed capacity to compare against trailer demands; the eCustomRim ST225/75R15 assembly states 2,860 pounds per tire.
A possible match for owners seeking a pair of black mod-wheel assemblies in ST205/75R15 with a 5-by-4.5-inch pattern. The supplied details omit load capacity, so weigh that information gap against your selection needs.

7. eCustomRim White Assembly
- Size: Set of 2
- Rim Size: 15 in
- Weight: 72 lb
Best for: White five-lug assemblies.
Why it ranks #7: This pre-mounted ST205/75D15 bias-ply assembly supports 1,820 pounds at 50 PSI and specifies a 5-lug, 4.5-inch bolt pattern.
A 15-by-5-inch white rim with a 5-lug, 4.5-inch bolt pattern comes paired with each ST205/75D15 bias-ply tire in this two-assembly package. The tire’s Load Range C rating, 1,820-pound maximum load and 50 PSI limit give trailer owners concrete specifications for evaluating a replacement pair.
The stated 3.19-inch center bore and 5-lug, 4.5-inch bolt pattern add useful wheel dimensions for checking compatibility, beyond the 15-by-5-inch rim size. Each bias-ply tire has a 27.2-inch overall diameter and is rated for up to 1,820 pounds at 50 PSI, allowing buyers to compare its basic dimensions and capacity with their trailer needs. The set contains two assemblies, so it is suited to pair replacement rather than a complete four-wheel change.
- Two ST205/75D15 bias-ply tire assemblies
- Load Range C with 1,820-pound maximum load per tire
- 15-by-5-inch rim with 3.19-inch center bore
- 5-lug, 4.5-inch bolt pattern and white finish
- The package contains two assemblies, not four.
Skip it if you need four wheels and tires together; the eCustomRim ST225/75R15 six-lug package is also a two-assembly set, so compare its size and pattern.
This pair suits owners whose trailer uses ST205/75D15 tires and a white 5-lug, 4.5-inch wheel setup. Its 1,820-pound maximum load and 50 PSI rating are key boundaries to compare with your trailer requirements.

8. eCustomRim Black Mod Assembly
- Size: 205/75D15
- Rim Size: 15 in
- Weight: 72 lb
Best for: Black five-lug bias-ply pair.
Why it ranks #8: The pair of ST205/75D15 bias-ply assemblies includes black 5-lug rims and lists 1,820 pounds per tire at 50 PSI.
Two pre-mounted black mod assemblies bring ST205/75D15 bias-ply tires and 15-by-5-inch rims together for a replacement pair. The 5-lug, 4.5-inch pattern, 3.19-inch center bore, Load Range C rating and 1,820-pound maximum load per tire make its core fit and capacity details explicit.
The stated rim dimensions and bolt pattern provide several measurements for checking a trailer’s wheel setup, while the 27.2-inch overall tire diameter offers another comparison point. Each tire is rated for up to 1,820 pounds at a maximum 50 PSI, giving buyers figures to assess against trailer requirements. The package includes two pre-mounted assemblies with valve stems, so it can simplify a pair replacement; it does not provide four assemblies for a full four-wheel change.
- Two pre-mounted assemblies with valve stems
- ST205/75D15 bias-ply tires, Load Range C
- Maximum load of 1,820 pounds at 50 PSI per tire
- Black 15-by-5-inch rims with 5-lug, 4.5-inch pattern
- Only two tire-and-wheel assemblies are included.
Skip it if you need a four-wheel package; the Free Country Grand Ride listing includes four ST225/75R15 tires, though rims are not specified.
This pair suits trailer owners needing black ST205/75D15 bias-ply assemblies with a five-lug, 4.5-inch pattern. Compare its 1,820-pound rating and 50 PSI maximum with your trailer requirements before selecting it.

9. GarveeTech Trailer Assembly
- Size: ST205/75D15
- Rim Size: 15 in
- Weight: 75 lb
Best for: Pre-mounted two-wheel replacements.
Why it ranks #9: This pair of ST205/75D15 bias-ply tires has Load Range C, 1,820-pound capacity at 50 PSI, and 5-lug 15-inch wheels.
A two-piece pre-mounted assembly pairs ST205/75D15 bias-ply tires with 15-inch white spoke wheels, giving trailer owners a tire-and-wheel package rather than separate components to assemble. Its 5-lug, 4.5-inch PCD and Load Range C rating make the key setup details clear for shoppers comparing replacement assemblies.
Each tire is rated for a maximum 1,820-pound load at 50 PSI, while nylon cord layers and double steel belts are specified as part of its construction. Those details help buyers weigh stated capacity and construction when choosing tires for utility, boat, camper, travel, farm, or hauling trailers. The set includes two assemblies, so it supplies a pair rather than a complete four-wheel set; the 15-inch wheel and bolt pattern are relevant when checking trailer setup compatibility.
- Two pre-mounted tire-and-wheel assemblies are included
- ST205/75D15 size with Load Range C, 6-ply rating
- Maximum load is 1,820 pounds at 50 PSI per tire
- Nylon cord layers and double steel belts are specified
- The two-piece set does not supply a full four-wheel replacement.
Skip it if you need four assemblies in one purchase; this listing includes two, not a complete four-wheel set.
A practical match for owners replacing a pair on a utility, boat, camper, travel, farm, or hauling trailer. Check that ST205/75D15 size and the 5-lug, 4.5-inch PCD match your wheel setup.

10. Garvee Trailer Tire Rims
- Size: ST205/75D15
- Rim Size: 14 in
- Weight: 75 lb
Best for: Black-rim two-tire setup.
Why it ranks #10: These ST205/75D15 bias-ply Load Range C tires list 1,820-pound capacity and include rims, but the listing gives a 14-inch rim size.
This two-piece Garvee package combines ST205/75D15 bias-ply tires with black 15-by-6-inch steel rims, so buyers can consider tire and wheel together. Each tire is listed at Load Range C, 6-ply and up to 1,820 pounds at 50 PSI, with a 5-lug, 4.5-inch bolt pattern.
The included steel rims and specified 5-lug, 4.5-inch pattern make the assembly details useful when matching a trailer wheel setup, while the ST205/75D15 tire size narrows the replacement search. A 1,820-pound maximum load at 50 PSI and Load Range C rating provide figures to compare with trailer needs. The two-piece package is described for utility, boat, family camping and cargo trailers, but it supplies a pair rather than four assemblies.
- Two trailer tires and rims are included
- ST205/75D15, Load Range C, 6-ply tires
- Maximum load is 1,820 pounds at 50 PSI per tire
- Black 15-by-6-inch steel rims have a 5-lug, 4.5-inch pattern
- The two-piece package is not a complete four-wheel set.
Skip it if you need four assemblies at once; the GarveeTech ST205/75D15 package also supplies only two.

View on AmazonAvoiding a size and wheel-fit mismatch
A matching tire size alone does not guarantee a fifth-wheel wheel assembly will fit. The listings show why: the eCustomRim ST225/75R15 assembly uses a 6-lug, 5.5-inch bolt pattern, while the ST205/75D15 assemblies from eCustomRim specify 5 lugs on a 4.5-inch pattern. The Free Country ST205/75R15 wheel listing also specifies 5×4.5 inches.
A tire-only product, such as the Carlisle Radial Trail HD or Free Country HD Trailer Tires, does not supply a rim at all. Before ordering, compare the trailer’s current tire size, wheel diameter, bolt pattern, and required load rating with the product details.
Do not assume a 15-inch tire assembly fits simply because its tire size resembles the one on your trailer. Product listings may also contain inconsistent details: Garvee’s assembly title says 15-inch rims, while its specifications state 14 inches, so verify that detail with the seller before purchase.
Why load range and tire type matter together
A higher ply rating or load range is useful only when the tire’s size and rating suit the trailer and its loaded weight. This selection spans 6-ply Load Range C bias tires rated at 1,820 pounds, Load Range E options rated at 2,400 to 2,860 pounds, and 12-ply 16-inch tires, including one listed at 3,960 pounds. Construction also varies: several products are bias-ply, while the fifth-wheel-specific Omni Trail and other options are radial.
These differences make direct substitution unsafe without checking the trailer’s required specifications. A tire’s listed maximum capacity is not a recommendation to exceed the trailer’s limits, and the assembly must be properly inflated and maintained.
Match the capacity per tire to the trailer’s requirements, confirm the required pressure and size, and consider whether an axle carries different loads. Do not infer a product’s load capacity when the listing does not provide it.
How to Choose Fifth-Wheel Trailer Tires
Trailer-specific fit and tire size
Start with the size and fitment specified for your fifth wheel, then compare the listing’s tire and rim details. This group ranges from ST205/75D15 and ST225/75R15 tires to ST235/80R16 and ST235/85R16 options. Rim sizes include 15 and 16 inches, and wheel assemblies may specify different lug patterns.
For example, the eCustomRim ST225/75R15 assembly has a 6-lug, 5.5-inch pattern, while several 5-lug products specify 4.5 inches. A buyer replacing an existing wheel assembly should prioritize exact size and bolt-pattern agreement; someone buying a tire only must separately confirm the correct rim.
Verify conflicting listing details before ordering.
Load rating and capacity
Choose a load rating that meets the fifth-wheel maker’s requirements at the trailer’s actual loaded weight. The listed options include Load Range C tires rated at 1,820 pounds, Load Range E tires rated from 2,400 to 2,860 pounds, and the Carlisle 12-ply tire with a listed 3,960-pound capacity. Some listings provide a capacity per tire, while others do not state one in the supplied specifications, so do not fill in missing figures by assumption.
Buyers whose trailer requirements match a higher-capacity tire may consider the listed E-rated or 12-ply choices; lighter-duty requirements may align with C-rated products. Check tire pressure, axle limits, and the trailer documentation before making the match.
Radial, bias-ply, and included wheels
Decide whether you need a radial or bias-ply tire, and whether a complete wheel assembly is necessary. Radial examples include the fifth-wheel-focused Omni Trail, the Carlisle Radial Trail HD, and the Free Country Grand Ride; several ST205/75D15 products are explicitly bias ply. Tire-only products such as the Carlisle and Free Country HD options require a suitable rim, while listings for eCustomRim, GarveeTech, and Garvee include tire-and-wheel assemblies.
A buyer seeking a replacement tire for an existing compatible wheel can choose a tire-only option; someone replacing assemblies may prefer a mounted set, after confirming the bolt pattern. Construction preference cannot override required size, capacity, or fitment.
Which tires should I choose for my fifth wheel?
For a fifth-wheel-specific 12-ply radial, choose Omni Trail Capability STR: its listing names fifth-wheel use and gives the ST235/80R16 size. If you need a 16-inch tire with an explicit high capacity, Carlisle Radial Trail HD lists 3,960 pounds, but confirm its fit because the listing does not specifically name fifth wheels. For a set of four 15-inch Load Range E radials, Free Country Grand Ride supplies Scuff Guard protection and a listed 2,830-pound capacity.
Choose eCustomRim Radial Assembly if you need a 6-lug wheel assembly and its 2,860-pound rating suits your trailer. For tire-only E-rated ST205/75R15 options, consider Free Country HD Trailer Tires.
In every case, verify size, load rating, pressure, and wheel fit against your trailer requirements before buying.

Frequently Asked Questions
How do I confirm the correct tire size and load rating for my fifth-wheel camper?
Check the trailer manufacturer’s specifications and the information on the existing tires, then match the required size and load rating. Also verify the required pressure and wheel fit. Do not assume that a tire fits because it looks similar; confirm every requirement for your specific trailer before ordering.
Can I replace bias-ply trailer tires with radial tires on a fifth wheel?
A radial may be an option, but confirm that its size, load rating, pressure requirements, and wheel fit meet your trailer’s specifications. The construction type alone does not establish compatibility. If you are unsure whether a change from bias-ply to radial is suitable, check with the trailer manufacturer or a qualified tire professional.
How often should fifth-wheel trailer tires be inspected or replaced?
Inspect the tires before trips and periodically while the trailer is in use, checking for visible damage, wear, and correct pressure. Replace tires when their condition or the manufacturer’s guidance indicates they should no longer be used. Follow the trailer and tire manufacturers’ recommendations, since no single interval fits every tire and use pattern.
How can I tell whether a listing includes wheels?
Read the complete title and listing details for terms such as “assembly,” “rim,” or a stated lug pattern. Some options here are identified as tire-and-wheel assemblies, while the Capability STR listing specifies two tires and does not state that wheels are included. Confirm the package contents before ordering.
Which option has a listed load capacity?
The Carlisle Radial Trail HD is listed as a 16-inch, 12-ply tire with a 3,960-pound capacity, though its listing does not specifically identify fifth-wheel use. Free Country Grand Ride lists a 2,830-pound capacity for its four 15-inch Load Range E radials. Confirm either option’s fit against your trailer requirements.
Final Words
Start with your trailer’s required size, load rating, pressure, and wheel fit, then choose a matching listing. Omni Trail Capability STR is the clearest fifth-wheel-specific pick here: it names fifth-wheel use and lists a 12-ply ST235/80R16 radial, but confirm whether you need rims. Carlisle lists a 3,960-pound capacity; Free Country Grand Ride offers four 15-inch Load Range E radials.
