A strong fifth-wheel tire choice pairs the correct tire size and bolt pattern with enough load capacity for your trailer, making these assemblies useful for owners replacing tires and wheels together. This lineup includes 14- and 15-inch options, radial and bias-ply designs, and 5×4.5- or 5×5-inch bolt patterns. The eCustomRim 2-Pack Radial Assembly leads because its listed radial tire supports 2,150 pounds per tire and fits a 5-lug-on-4.5-inch pattern.
Other options suit different needs, including a 10-ply Free Country set and assemblies specified for 5×5-inch fitment. Product listings do not establish universal fifth-wheel compatibility, so verify your trailer’s required tire size, load rating, wheel dimensions, and bolt pattern before ordering.
The eCustomRim 2-Pack Radial Assembly is the leading choice because its ST205/75R15 radial tires are rated for 2,150 pounds each, and the included 15×6-inch rims use a 5-lug-on-4.5-inch bolt pattern. That combination gives buyers key fitment and load details in one assembly. It is not a universal fit: confirm your trailer calls for this tire size and bolt pattern, and that the tires’ capacity meets its requirements.

Detailed Reviews: Best Rated 5Th Wheel Tires

#1 · Best Overall
1. eCustomRim Radial Assembly
- Size: 205/75R15
- Wheel Size: 15 in
- Rim Size: 15 in
- Compatible with Vehicle Type: Motorhome, Trailer
Best for: Higher-Capacity Radial Assembly.
Why it ranks #1: Its ST205/75R15 radial tire supports 2,150 pounds per tire, with a 15×6-inch rim and 5-lug-on-4.5-inch pattern.
A listed 2,150-pound maximum load gives this eCustomRim radial assembly a concrete capacity reference for trailer owners comparing tire limits. The ST205/75R15 Load Range D tire sits on a 15×6-inch rim with a 5-lug, 4.5-inch bolt pattern, making hub fitment specific and checkable.
The radial tire's 65 PSI maximum and 2,150-pound load rating help owners compare the assembly's listed operating limits with trailer requirements. Its 15×6-inch rim, 3.19-inch center bore, and 5-lug-on-4.5-inch pattern provide several dimensions for checking wheel fit. Since the tire and rim are supplied together, it can support a combined replacement workflow; confirming hub pattern and bore before installation helps avoid a mismatch. The stated tire size is ST205/75R15.
- Radial Load Range D tire
- Maximum load listed as 2,150 pounds
- 15×6-inch rim with 3.19-inch center bore
- 5-lug, 4.5-inch bolt pattern
- The 5-lug, 4.5-inch pattern will not fit hubs with a different bolt pattern.
Skip it if you need a 5×5 bolt pattern; this assembly uses a 5-lug, 4.5-inch pattern instead.
For trailer owners seeking a radial ST205/75R15 assembly with a listed 2,150-pound maximum load, this eCustomRim set offers detailed wheel dimensions. Its 5-lug, 4.5-inch pattern and center bore are important fit boundaries.

#2 · Highest Ply Rating
2. Free Country 10-Ply Assembly
- Size: 5×4.5"PCD
- Wheel Size: 15 in
- Rim Size: 15 in
- Compatible with Vehicle Type: Trailer
Best for: Ten-Ply 5×4.5 Set.
Why it ranks #2: The ST205/75R15 tire is rated 10PR, Load Range E, and the listed wheel uses a 5×4.5-inch pattern.
The 10-ply, Load Range E tire specification is the clearest differentiator of this Free Country ST205/75R15 assembly, giving buyers a defined tire class to compare with their trailer's needs. Its black 15-inch mod wheels use a 5×4.5-inch PCD, a key detail for checking hub compatibility.
This two-piece set pairs ST205/75R15 tires marked 10PR and Load Range E with 15-inch alloy-steel wheels. The 5×4.5-inch PCD gives owners a direct way to check whether the wheels match their trailer hubs before installation. The higher ply and load-range designations distinguish its tire specification from lower-rated options, but the supplied product details do not give a numerical load capacity or pressure limit, so those figures cannot be compared here.
- 10PR, Load Range E tire specification
- ST205/75R15 tire size
- 15-inch alloy-steel wheels
- 5×4.5-inch PCD specified
- The supplied specifications do not state a numerical load capacity.
Skip it if you need a published numerical load limit before choosing; this listing supplies none for this assembly.
Trailer owners seeking a 10PR Load Range E tire and 15-inch wheel with a 5×4.5-inch PCD can use these details to check fit. The missing numerical capacity is a boundary for load comparisons.

#3 · 5×5 Capacity Pick
3. ROCKMAN White Spoke Assembly
- Size: ST205/75R15 /5×5
- Rim Size: 15 in
Best for: 5×5 White-Spoke Assembly.
Why it ranks #3: This 15-inch ST205/75R15 assembly lists a 2,150-pound load capacity and a 5×5-inch wheel pattern.
A listed 2,150-pound load capacity gives this ROCKMAN ST205/75R15 assembly a concrete figure for trailer owners assessing tire requirements. Its 8-ply, Load Range D tire comes with a 15-inch white spoke rim and a 5×5 pattern, making the wheel configuration clear for fit checks.
The tire's 2,150-pound listed capacity and 8PR Load Range D marking help buyers compare its stated rating with trailer demands. Its ST205/75R15 size pairs with a 15-inch rim, while the 5×5 pattern specifies the hub configuration to verify before installation. Arriving as a tire-and-wheel assembly can simplify replacing both components together. The white spoke rim gives the setup a distinctive appearance, but the 5×5 pattern remains the key compatibility boundary.
- Load capacity listed as 2,150 pounds
- 8PR, Load Range D tire
- 15-inch white spoke rim
- 5×5 bolt pattern specified
- The 5×5 pattern rules out hubs with a different bolt configuration.
Skip it if you have 5×4.5 hubs; this ROCKMAN assembly uses a 5×5 pattern instead.
This ROCKMAN assembly suits trailer owners seeking an ST205/75R15 tire with a listed 2,150-pound capacity and white spoke wheel. Confirm the 5×5 hub pattern; that dimension determines compatibility.

#4 · Black 5×5 Option
4. ROCKMAN Black Mod Assembly
- Size: ST205/75R15 8PR /5×5
- Wheel Size: 15 in
- Rim Size: 15 in
- Compatible with Vehicle Type: Trailer
Best for: Eight-Ply 5×5 Assembly.
Why it ranks #4: Its ST205/75R15 tire is 8-ply, Load Range D, and comes on a listed 15-inch black mod rim with 5×5 fitment.
An 8-ply, Load Range D tire paired with a 15-inch black mod rim gives this ROCKMAN set a clearly specified trailer-wheel configuration. Its ST205/75R15 size and 5×5-inch pattern help owners check both tire and hub requirements, while the alloy-steel wheel arrives as part of the assembly.
The ST205/75R15 tire size and 8PR Load Range D designation provide useful information for comparing this assembly with a trailer's existing setup. Its 15-inch alloy-steel wheel has a 5×5 pattern, which narrows compatibility to hubs with that bolt configuration. Because the tire and rim are paired, buyers can replace both components together; confirming the pattern and wheel diameter remains essential before installation. The supplied specifications do not state a load capacity.
- 8PR, Load Range D tire specification
- 15-inch alloy-steel wheel
- 5×5 bolt pattern is specified
- Black mod-rim style
- A specific load-capacity figure is not provided in the supplied specifications.
Skip it if you need a stated load-capacity figure to compare assemblies; no capacity number is supplied for this ROCKMAN set.
This ROCKMAN set fits buyers looking for an ST205/75R15 tire and 15-inch wheel in a 5×5 configuration. Its listed 8PR Load Range D rating is useful, but the supplied specifications omit a capacity figure.

5. Free Country 8-Ply Assembly
- Size: ST205/75R15 /5×4.5
- Wheel Size: 15 in
- Rim Size: 15 in
- Compatible with Vehicle Type: Trailer
Best for: Eight-Ply 5×4.5 Set.
Why it ranks #5: The ST205/75R15 tire is specified as 8PR, Load Range D, with a 15-inch wheel and 5×4.5-inch pattern.
The 8PR, Load Range D tire specification gives this Free Country ST205/75R15 assembly a defined rating class, while its 5×4.5-inch pattern identifies the intended hub configuration. Its black 15-inch alloy-steel mod wheels come paired with the tires, simplifying replacement when both components are needed.
The tire's ST205/75R15 size and 8PR Load Range D designation help buyers compare it with their current trailer setup. The paired 15-inch alloy-steel wheels use a 5×4.5 pattern, providing a specific hub-fit check before installation. Since the listing describes a tire-and-wheel set, it supports replacing both components together rather than sourcing them separately. The supplied specifications do not state a numerical load capacity, so buyers cannot use this listing alone for that comparison.
- 8PR, Load Range D tire specification
- ST205/75R15 tire size

#6 · Silver 5×5 Option
6. ROCKMAN Silver Mod Assembly
- Size: ST205/75R15 8PR/5×5
- Wheel Size: 15 in
- Rim Size: 15 in
- Compatible with Vehicle Type: Trailer
Best for: Silver Aluminum 5×5 Set.
Why it ranks #6: This ST205/75R15 assembly specifies an 8-ply Load Range D tire and a silver 15-inch wheel with 5×5 fitment.
Silver aluminum wheels distinguish this ROCKMAN ST205/75R15 assembly from steel-wheel options, while the 5×5 PCD identifies its hub-fit requirement. The 8-ply, Load Range D tire specification provides a clear rating class, and the 15-inch wheel size helps owners compare it with their current setup.
This assembly combines an ST205/75R15 tire marked 8PR and Load Range D with a 15-inch aluminum wheel. Its 5×5 PCD is the central compatibility check, since hubs using a different bolt pattern will not match. The silver mod-rim appearance also identifies the wheel finish, while the aluminum material differentiates its wheel construction. The supplied specifications do not list a load-capacity figure, so buyers should not infer one from the tire's ply or load-range markings.
- Aluminum wheel construction
- Silver mod-rim finish
- 15-inch wheel with 5×5 PCD
- 8PR, Load Range D tire specification
- The supplied specifications provide no numerical load-capacity figure.
Skip it if you need a stated load-capacity number for comparison; this listing gives no numerical figure for the assembly.
Consider this ROCKMAN assembly if your trailer uses a 5×5 pattern and you want an aluminum 15-inch wheel with an ST205/75R15 tire. Its supplied details do not include a numerical load capacity.

7. Free Country Bias-Ply Assembly
- Size: ST205/75D15 / 5×5" PCD / 6PR
- Rim Size: 15 in
Best for: 5×5 Hub Pattern Match.
Why it ranks #7: Its ST205/75D15 bias-ply tire lists a 1,820-pound load capacity, 6PR construction, and a 5×5-inch pattern.
The 5×5-inch bolt pattern is the practical differentiator of this Free Country ST205/75D15 trailer tire and wheel, giving owners with matching hubs a specific fit target. Its 6-ply, Load Range C tire is listed with a 1,820-pound capacity, while the 15-inch rim completes the assembly.
This assembly pairs a 15-inch rim with an ST205/75D15 tire, so buyers can evaluate the tire and wheel together rather than source them separately. The 5×5-inch PCD is the key hub-fit detail, making it relevant to trailers using that pattern rather than 5×4.5 hubs. Its 6PR, Load Range C specification and 1,820-pound load capacity set a clear operating boundary for comparing the tire with a trailer's requirements.
- 15-inch wheel and ST205/75D15 tire assembly
- 5×5-inch PCD specified
- 6-ply, Load Range C tire
- Listed load capacity of 1,820 pounds
- The 5×5-inch bolt pattern excludes hubs requiring a different pattern.
Skip it if you have 5×4.5 hubs; this assembly's 5×5-inch PCD will not match that pattern.
Choose this Free Country assembly when your trailer requires a 15-inch wheel with a 5×5-inch PCD and the listed 1,820-pound capacity suits your needs. The bolt pattern is a firm compatibility boundary.

8. Garvee Bias-Ply Assembly
- Size: ST205/75D15
- Wheel Size: 15 in
- Rim Size: 14 in
- Compatible with Vehicle Type: Trailer
Best for: Quieter-Ride Bias-Ply Set.
Why it ranks #8: The set includes two ST205/75D15 tires rated for 1,820 pounds each, with 15-inch rims and a 5-lug-on-4.5-inch pattern.
A variable-pitch tread is the defining feature of this Garvee trailer tire set, with the stated purpose of minimizing road noise for a quieter ride. The ST205/75D15 tires come on 15-inch rims with a 5-lug, 4.5-inch pattern, giving buyers specific dimensions to check against their trailer.
The 6-ply Load Range C tires are listed with a maximum load of 1,820 pounds and maximum pressure of 50 PSI, helping buyers compare the stated limits with their trailer requirements. Their all-season capability and durable nylon cords are identified in the product details, while the variable-pitch tread is intended to reduce road noise. The 15-inch rims and 5-lug-on-4.5-inch pattern make hub and wheel sizing important compatibility checks before installation.
- Variable-pitch tread intended to minimize road noise
- All-season capability is specified
- Maximum load listed as 1,820 pounds
- 15-inch rims with 5-lug, 4.5-inch pattern
- Load Range C is limited to the listed 1,820-pound maximum load.
Skip it if you need more than 1,820 pounds of listed tire capacity; the Load Range C rating sets that limit.
This set suits trailer owners seeking a 15-inch tire-and-rim assembly with a stated noise-minimizing tread feature. Match the 5-lug, 4.5-inch pattern and ensure the listed load limit meets your trailer's needs.

9. eCustomRim Bias-Ply Assembly
- Size: 205/75D15
- Wheel Size: 15 in
- Rim Size: 15 in
- Compatible with Vehicle Type: Trailer
Best for: Bias-Ply 5×5 Replacement.
Why it ranks #9: This 205/75D15 bias-ply assembly supports 1,820 pounds per tire and lists a 15×5-inch rim with 5-lug-on-5-inch fitment.
A 5-lug-on-5-inch bolt pattern defines this eCustomRim assembly, offering a specific match point for trailer hubs using that configuration. The 205/75D15 bias-ply tire is listed at 1,820 pounds maximum load and 50 PSI, and comes mounted on a 15×5-inch steel rim.
The bias-ply construction and Load Range C rating identify this tire's type and class, while the stated 1,820-pound maximum load and 50 PSI provide operating limits for comparison. Its 15×5-inch rim has a 3.30-inch center bore and a 5-lug-on-5-inch pattern, which lets buyers check several fit dimensions together. As a paired assembly, it combines tire and wheel replacement in one purchase, but its bias-ply construction is a consideration for buyers specifically seeking radial tires.
- Bias-ply 205/75D15 tire
- Maximum load listed as 1,820 pounds
- 15×5-inch alloy-steel rim
- 5-lug-on-5-inch pattern and 3.30-inch center bore
- Bias-ply construction does not suit buyers specifically requiring a radial tire.
Skip it if you require radial construction; this eCustomRim assembly is explicitly a bias-ply tire.
This assembly suits trailer owners who need a bias-ply 205/75D15 tire on a 5×5-pattern wheel and whose requirements fall within its listed capacity. Its construction and hub dimensions define the fit.

10. Free Country 14-Inch Assembly
- Size: ST205/75R14 /8PR /5×4.5
- Wheel Size: 14 in
- Rim Size: 14 in
- Compatible with Vehicle Type: Trailer
Best for: 14-Inch Trailer Wheel Set.
Why it ranks #10: This ST205/75R14 8PR assembly offers a 14-inch white spoke wheel, but its listing provides fewer load and fitment details.
The ST205/75R14 tire size paired with a 14-inch white spoke wheel gives this Free Country set a ready-mounted option for trailers using that wheel format. Its 8-ply rating and 105N marking make the listed tire specification clear, while the 5×4.5 bolt pattern helps buyers check wheel compatibility.
This two-piece set combines the ST205/75R14 tire with a 14-inch alloy-steel wheel, so the tire and wheel arrive as a matched assembly rather than separate components. The 5×4.5 bolt pattern provides a concrete compatibility check for trailer hubs, and the 8PR, 105N markings identify the listed tire construction and speed rating. Its white spoke finish also distinguishes the wheel visually. The key fit boundary is the 14-inch size and 5×4.5 pattern.
- Two tire-and-wheel assemblies in the set
- 14-inch alloy-steel wheels
- 5×4.5 bolt pattern is specified
- 8PR and 105N tire markings
- 14-inch wheels limit use to trailers requiring that wheel size.
Skip it if you need 15-inch wheels or a bolt pattern other than 5×4.5; this set is specifically 14-inch.
A trailer owner replacing 14-inch wheels can consider this paired tire-and-wheel set when the hub uses a 5×4.5 pattern. Check those dimensions before purchase; its 14-inch wheel size is the central fit boundary.

View on AmazonAvoid bolt-pattern and tire-size mismatches
A matching tire size alone does not guarantee that an assembly will fit your fifth-wheel trailer. These products include both 5-lug-on-4.5-inch and 5×5-inch patterns, and their listed wheel sizes include 14 and 15 inches. For example, the eCustomRim Radial Assembly uses a 5-lug-on-4.5-inch pattern, while the ROCKMAN Black Mod Assembly specifies 5×5 fitment.
Ordering by a familiar tire size without checking the hub’s bolt pattern can leave you with a wheel that will not mount. Compare the complete tire designation, wheel diameter, lug count, and bolt-circle measurement against your trailer’s existing equipment or manufacturer requirements.
Also check rim width and center bore when those details are available; the eCustomRim Radial Assembly lists a 15×6-inch rim and 3.19-inch center bore. The listings do not confirm compatibility with every fifth wheel, so treat each assembly as a specific fitment, not a universal replacement.
Understand the radial and bias-ply trade-off
Radial and bias-ply designs are different constructions, and the listings do not establish that either type is best for every towing situation. The radial options include the eCustomRim Radial Assembly, specified at 2,150 pounds per tire, and several ST205/75R15 assemblies. Bias-ply examples include the Garvee Bias-Ply Assembly and eCustomRim Bias-Ply Assembly, both listed at 1,820 pounds per tire.
Do not assume construction alone determines whether a tire is suitable: compare its exact load rating and size with your trailer’s requirements. A buyer replacing an existing bias-ply setup may prefer to match that construction, while someone considering a radial option should verify that the trailer’s specified tire type permits it.
The supplied product details do not include comparative tests, heat performance, or expected service life, so those qualities cannot be ranked here.
How to Choose Fifth-Wheel Trailer Tires
Tire size and wheel diameter
Start by matching the full tire size and wheel diameter required by your trailer. The products include ST205/75R14 and ST205/75R15 radial options, as well as ST205/75D15 bias-ply choices; listed wheel sizes are 14 or 15 inches. The letter differs between R and D, so do not treat those size designations as interchangeable.
The Free Country 14-Inch Assembly is the only listed 14-inch option, while most choices use a 15-inch wheel. Buyers replacing an existing 14-inch assembly should focus on that exact fitment; those whose trailer specifies 15 inches can compare the broader 15-inch selection.
Always follow the trailer maker’s size requirements rather than selecting a size based only on appearance.
Load capacity and ply rating
Choose a tire whose specified load capacity meets the trailer’s requirements, with every tire position accounted for. The eCustomRim Radial Assembly lists 2,150 pounds per tire, while the Garvee Bias-Ply Assembly, Free Country Bias-Ply Assembly, and eCustomRim Bias-Ply Assembly each list 1,820 pounds. Ply ratings also vary: the Free Country 10-Ply Assembly is 10PR, several models specify 8PR, and the Free Country Bias-Ply Assembly lists 6PR.
Higher ply rating does not by itself confirm sufficient capacity for a particular trailer, so check the tire’s rating and your trailer documentation. Buyers needing the listed 2,150-pound capacity can compare the eCustomRim Radial Assembly and ROCKMAN White Spoke Assembly; those matching a lower-rated existing setup have several 1,820-pound options.
Bolt pattern and rim fitment
Match the wheel’s bolt pattern to your trailer hub before choosing among these assemblies. The listings show 5-lug-on-4.5-inch fitment on the eCustomRim Radial Assembly and Garvee Bias-Ply Assembly, while multiple products specify a 5×5-inch pattern. Those measurements are not interchangeable.
Rim details vary as well: the eCustomRim Radial Assembly lists a 15×6-inch rim and 3.19-inch center bore, and the eCustomRim Bias-Ply Assembly lists a 15×5-inch rim and 3.30-inch center bore. Buyers whose hubs require 5×4.5-inch fitment should compare the Free Country 10-Ply Assembly or eCustomRim Radial Assembly; 5×5-inch hubs point toward options such as the ROCKMAN White Spoke Assembly.
Verify all dimensions against the trailer’s specified fitment.
Which fifth-wheel tire assembly should I choose?
Choose the eCustomRim Radial Assembly if your trailer requires ST205/75R15 tires, a 5-lug-on-4.5-inch pattern, and benefits from its listed 2,150-pound capacity per tire. For a 10PR, Load Range E option with a 5×4.5-inch pattern, consider the Free Country 10-Ply Assembly. If your hub uses a 5×5 pattern and you need a listed 2,150-pound capacity, the ROCKMAN White Spoke Assembly is a relevant match; the ROCKMAN Black Mod Assembly offers an 8-ply, Load Range D alternative.
Buyers seeking a listed 1,820-pound bias-ply assembly can compare the Free Country Bias-Ply Assembly and Garvee Bias-Ply Assembly. Confirm tire size, load requirements, and complete wheel fitment against your trailer before ordering.

Frequently Asked Questions
How can I confirm a tire and wheel assembly fits my fifth-wheel trailer?
Compare the assembly’s tire size, wheel size, bolt pattern, and load capacity with your trailer’s requirements. Check the trailer documentation or existing wheel and tire markings, and verify complete wheel fitment rather than relying on one matching detail. The listed assemblies have different sizes and bolt patterns, so none should be assumed to fit universally.
Should I choose radial or bias-ply trailer tires for my towing use?
Choose the construction specified or approved for your trailer and intended use. The products listed include both radial and bias-ply assemblies, but the titles alone do not establish which is better for your towing conditions. Check your trailer documentation and confirm the selected tire’s size, load capacity, and wheel fitment before ordering.
What tire load capacity should I select for a fifth-wheel trailer?
Select tires whose load capacity meets or exceeds your trailer’s requirements. Check the trailer’s documentation and account for the required capacity at each tire position; do not rely on the assembly’s fit or appearance alone. For example, the editorial pick lists 2,150 pounds per tire, but that capacity is suitable only if it meets your trailer’s needs.
Does a 5×4.5 bolt pattern fit a 5×5 hub?
No; these are different bolt patterns and should not be treated as interchangeable. Match the wheel’s bolt pattern to the trailer hub’s requirements, along with the tire size and other fitment details. The listed products include both patterns, so confirm the exact pattern before ordering rather than relying on the tire size alone.
What details should I compare when choosing between these assemblies?
Compare tire size, radial or bias-ply construction, listed load capacity or load range, rim dimensions, and bolt pattern. These details vary across the assemblies, and a match on one specification does not confirm complete fitment. Verify the full set against your trailer’s requirements before choosing or ordering a replacement.
Final Words
Start with your trailer’s required tire size, wheel bolt pattern, and load capacity, then compare those details across the assemblies. The eCustomRim Radial Assembly is the leading choice when your trailer calls for ST205/75R15 tires, a 5-lug-on-4.5-inch pattern, and at least its listed 2,150-pound capacity per tire. Consider the other listed options only when their specifications match your trailer.
Confirm complete fitment before ordering.
