A strong trailer wheel choice pairs the correct bolt pattern and rim size with a tire load rating that meets your trailer’s needs, making these assemblies useful for owners replacing complete tire-and-wheel sets. This roundup covers 10 options from 12 to 15 inches, including bias-ply and radial tires, several lug patterns, and load ratings from 990 to 2,860 pounds per tire where specified. The eCustomRim 15-inch assemblies lead for buyers seeking a ready-to-fit, two-wheel set with a stated 1,820-pound tire rating and a 5-lug, 4.5-inch pattern.
Other picks suit smaller wheels, 6-lug hubs, or a higher stated load rating. Match the measurements and capacity to your trailer before ordering; wheel diameter alone does not establish compatibility.
The eCustomRim 15-inch black assemblies are the best overall choice in this group for many trailers that use a 5-lug, 4.5-inch pattern. Each ST205/75D15 bias-ply tire is rated for 1,820 pounds at 50 PSI, and the 15-by-5-inch rims have a 3.19-inch center bore. The two-pack includes pre-mounted assemblies with valve stems, according to the verified product details.
Choose another option if your trailer requires a different wheel diameter, bolt pattern, or tire construction.

Detailed Reviews: Best Wheels For A Trailer

#1 · Best Overall
1. eCustomRim 15-Inch Black Assembly
- Material Type: Alloy Steel
- Wheel Size: 15 in
- Rim Size: 15 in
Best for: Black five-lug 15-inch replacements.
Why it ranks #1: The two-pack includes pre-mounted assemblies with valve stems; each ST205/75D15 tire is rated for 1,820 pounds and fits a 5-lug, 4.5-inch pattern.
A black mod rim pairs with ST205/75D15 bias-ply tires rated for 1,820 pounds each, giving compatible trailers a matched two-assembly replacement set. The 15-by-5-inch rims use a five-on-4.5-inch bolt pattern, and the tires have a 27.2-inch overall diameter with a 50 PSI maximum.
The Load Range C tires and 1,820-pound maximum rating provide a defined capacity reference for comparing with trailer requirements. A 50 PSI maximum pressure states the inflation ceiling, while the 15-by-5-inch rim, 3.19-inch center bore, and five-on-4.5-inch pattern clarify wheel fitment. The 27.2-inch diameter helps with clearance comparisons. Two pre-mounted assemblies with valve stems are included, making this a combined tire-and-wheel replacement package.
- Two pre-mounted assemblies with valve stems
- 1,820-pound maximum load per tire
- 15-by-5-inch rim and five-on-4.5-inch pattern
- 27.2-inch diameter and 50 PSI maximum specified
- Bias-ply construction is not the right match for buyers requiring radial tires.
Skip it if you require radial tires; the eCustomRim ST225/75R15 Load E assembly is radial and uses a six-lug pattern.
A sensible option for trailer owners replacing two compatible 15-inch, five-lug assemblies and preferring black mod wheels. Compare the 4.5-inch bolt pattern, 3.19-inch center bore, and bias-ply construction with your needs.

#2 · White Wheel Option
2. eCustomRim 15-Inch White Assembly
- Material Type: Metal
- Wheel Size: 15 in
- Rim Size: 15 in
Best for: 15-inch five-lug trailer setups.
Why it ranks #2: This two-pack shares the 1,820-pound rating and 5-lug, 4.5-inch fitment, with 15-by-5-inch rims and a stated two-year warranty.
A 1,820-pound-per-tire rating pairs with a 15-inch wheel, giving compatible trailer owners a pre-matched two-wheel set for replacing worn assemblies. Its Load Range C bias-ply tires operate at up to 50 PSI, while the stated five-lug, 4.5-inch pattern identifies the hub arrangement this package is intended to fit.
The 27.2-inch overall diameter and ST205/75D15 size give you concrete dimensions to compare with your trailer’s existing setup before ordering. Each tire is rated for 1,820 pounds, and the 50 PSI maximum provides a clear inflation ceiling to follow. The 15-by-5-inch rim, 3.19-inch center bore, and five-on-4.5-inch bolt pattern help identify compatible hubs. Because this is a two-pack of tire assemblies, it can replace two wheels in one purchase.
- Two tire assemblies included
- 1,820-pound maximum load per tire
- 15-by-5-inch rim with five-on-4.5-inch pattern
- 27.2-inch overall diameter specified
- Bias-ply construction may not suit buyers specifically seeking radial tires.
Skip it if you need radial construction or a different bolt pattern; the eCustomRim ST225/75R15 radial assembly is a better match for radial, six-lug setups.
A practical choice for trailer owners replacing two compatible 15-inch, five-lug assemblies who need the listed 1,820-pound tire rating. Check the 4.5-inch bolt pattern, center bore, and overall diameter against the existing wheel setup.

#3 · Highest Rated Load
3. eCustomRim 15-Inch Radial Assembly
- Material Type: Alloy Steel
- Wheel Size: 15 in
- Rim Size: 15 in
Best for: Six-lug radial high-load trailers.
Why it ranks #3: Its radial ST225/75R15 tire is rated for 2,860 pounds at 80 PSI, with a 6-lug, 5.5-inch pattern for compatible hubs.
A 2,860-pound maximum load rating per tire makes this radial two-pack a clearly specified option for compatible higher-load trailer setups. The ST225/75R15 tires are Load Range E and rated to 80 PSI, while the 15-by-6-inch rims use a six-lug, 5.5-inch pattern.
The radial construction and 28.1-inch overall diameter give buyers useful details for comparing tire behavior and clearance with an existing trailer setup. Each tire’s 2,860-pound maximum rating and 80 PSI limit specify load and inflation boundaries. The 15-by-6-inch rim, 4.25-inch center bore, and six-on-5.5-inch pattern clarify the wheel interface. Since the package includes two assemblies, owners replacing a pair can source matching tires and rims together.
- Radial tires rated to 2,860 pounds each
- Load Range E and 80 PSI maximum
- 15-by-6-inch rims with six-on-5.5-inch pattern
- 28.1-inch overall diameter specified
- The six-lug, 5.5-inch pattern will not suit trailers with a different hub pattern.
Skip it if you have a five-lug, 4.5-inch hub; the eCustomRim ST205/75D15 assembly uses that pattern instead.
A strong specification match for owners of compatible six-lug trailers needing two radial Load Range E assemblies. Check the 5.5-inch bolt pattern, center bore, and 28.1-inch diameter against the existing setup.

#4 · 13-Inch Fit
4. eCustomRim 13-Inch Assembly
- Material Type: Alloy Steel
- Wheel Size: 13 in
- Rim Size: 13 in
Best for: 13-inch utility trailer replacements.
Why it ranks #4: The two pre-mounted ST175/80D13 assemblies include valve stems and use a 5-lug, 4.5-inch pattern, with a 1,360-pound tire rating.
This two-assembly package combines ST175/80D13 bias-ply tires with 13-inch rims, giving owners of compatible smaller-wheel trailers a matched replacement set. The tires carry a 1,360-pound maximum load rating at up to 50 PSI, and the five-lug, 4.5-inch pattern specifies the hub layout.
The 24.4-inch overall diameter and ST175/80D13 size give buyers specific measurements for comparing against the trailer’s current tires. Each tire is rated for up to 1,360 pounds, with 50 PSI as the maximum pressure. The 13-by-4.5-inch rim and five-on-4.5-inch bolt pattern clarify wheel and hub compatibility. Two assemblies arrive pre-mounted with valve stems, so the package combines the tire and wheel rather than requiring separate mounting before installation.
- Two pre-mounted assemblies with valve stems
- 1,360-pound maximum load per tire
- 13-inch rim and five-on-4.5-inch bolt pattern
- 24.4-inch overall diameter specified
- The 1,360-pound tire rating is lower than higher-capacity trailer tire options.
Skip it if you need radial tires or a higher per-tire rating; the eCustomRim ST225/75R15 Load E assembly is rated for up to 2,860 pounds.
This set suits owners of compatible utility or recreational trailers using 13-inch, five-lug wheels who want two pre-mounted assemblies. Its 1,360-pound rating and 24.4-inch diameter are key boundaries to compare with existing requirements.

#5 · 4-Lug Fit
5. eCustomRim 12-Inch 4-Lug Assembly
- Material Type: Steel
- Wheel Size: 12 in
- Rim Size: 12 in
Best for: Four-lug 12-inch trailer wheels.
Why it ranks #5: This assembled 4.80-12 tire-and-wheel set suits compatible 4-lug hubs, with a stated 990-pound rating and 12-by-4-inch rim.
A four-lug, 4-inch bolt pattern sets this 4.80-12 two-pack apart for compatible small trailer hubs. The white steel rims arrive assembled with DOT-approved bias-ply tires and valve stems, and each Load Range C tire is rated for 990 pounds at up to 90 PSI.
The 20.5-inch overall diameter and 4.80-12 size give owners concrete dimensions to compare with current tires and available clearance. A 2.83-inch center bore and four-on-4-inch pattern specify the rim’s hub interface, while the 990-pound maximum load and 90 PSI limit define tire operating figures. Because the tire, wheel, and valve stem come assembled, buyers receive a ready-to-install pair rather than separate components requiring mounting.
- Two assembled tire, wheel, and valve-stem units
- DOT-approved bias-ply tires
- 990-pound maximum load and 90 PSI limit
- Four-on-4-inch pattern and 2.83-inch center bore
- The 990-pound maximum load per tire is limiting for heavier trailer requirements.
Skip it if you need a five-lug 12-inch assembly; the GarveeTech 4.80-12 set uses five-on-4.5-inch wheels.
This suits owners of compatible utility or cargo trailers with four-lug, 4-inch hubs seeking two assembled 12-inch wheels. The 990-pound rating and 20.5-inch diameter remain key load and clearance checks.

6. GarveeTech 12-Inch Assembly
- Material Type: Alloy Steel
- Wheel Size: 12 in
- Rim Size: 12 in
Best for: Compact utility and boat trailers.
Why it ranks #6: The two-pack provides 4.80-12 bias-ply tires rated for 990 pounds at 90 PSI, mounted on white 12-inch wheels with a 5-lug pattern.
A 4.80-12 tire and wheel pairing comes as a two-pack on white spoke rims, giving compatible compact trailers two matching assemblies. Each bias-ply, Load Range C tire has a 990-pound maximum load rating at 90 PSI, while the five-lug, 4.5-inch pattern specifies its wheel attachment layout.
The 12-inch wheels and 4.80-12 tire size offer a defined small-wheel configuration for utility and boat trailer applications listed by the manufacturer. Nylon cord layers and double steel belts are specified as part of the tire construction, while the Load Range C, 6PR designation and 990-pound maximum load provide useful load-matching details. The 90 PSI maximum is the stated pressure limit. Two assemblies are included, with white spoke wheels and a five-on-4.5-inch pattern.
- Two 4.80-12 assemblies included
- 990-pound maximum load per tire
- Nylon cord layers and double steel belts
- Five-lug, 4.5-inch pattern on 12-inch wheels
- The 990-pound maximum load per tire limits suitability for heavier trailer loads.
Skip it if you need a four-lug 4.80-12 wheel; the eCustomRim 4.80-12 assembly uses a four-on-4-inch pattern.
A match for owners of compatible utility, boat, camper, or farm trailers using 12-inch five-lug wheels. Compare the 4.5-inch bolt pattern and 990-pound tire rating with your trailer’s hub and load needs.

7. Garvee 15-Inch Assembly
- Material Type: Rubber
- Wheel Size: 68.4 centimeters
- Rim Size: 14 in
Best for: 15-inch heavy-load trailer pairs.
Why it ranks #7: This two-pack lists ST205/75D15 tires rated for 1,820 pounds at 50 PSI and black 15-by-6-inch rims with a 5-lug, 4.5-inch pattern.
Each ST205/75D15 tire is rated for up to 1,820 pounds, providing a stated load figure for buyers replacing trailer wheels in pairs. Garvee includes black 15-by-6-inch steel rims with a five-on-4.5-inch pattern, alongside 6-ply, Load Range C bias-ply tires rated to 50 PSI.
The two-pack combines the tires and rims, avoiding the need to source those components separately. Its 15-inch rim and five-on-4.5-inch bolt pattern help buyers check the wheel configuration against their trailer, while the ST205/75D15 size and bias-ply construction clarify the tire type. The 1,820-pound maximum load and 50 PSI limit provide specific operating figures. The listing describes the rims as 15 by 6 inches, while the specifications separately give a 14-inch rim size, so the stated dimensions conflict.
- Two tires and rims included
- 1,820-pound maximum load per tire
- 6-ply, Load Range C bias-ply tires
- Five-on-4.5-inch bolt pattern
- The listing conflicts on rim size, stating both 15 inches and 14 inches.
Skip it if you need an unambiguous rim diameter; the eCustomRim ST205/75D15 assembly states a 15-by-5-inch rim.
A potential match for utility, boat, camper, or cargo trailer owners needing two ST205/75D15 Load Range C assemblies. Resolve the conflicting rim-size information and compare the bolt pattern before choosing it.

8. Free Country 14-Inch Assembly
- Material Type: Alloy Steel
- Wheel Size: 14 in
- Rim Size: 14 in
Best for: 14-inch white spoke replacements.
Why it ranks #8: The two-pack offers ST205/75R14 tires with 8-ply construction and white spoke wheels; verify the missing load rating and rim fitment details.
The ST205/75R14 size and white spoke wheel give trailer owners a clearly identified 14-inch radial tire-and-wheel option. Its 8PR and 105N markings help distinguish the tire’s stated construction and service designation when comparing replacements, while the listed 5-by-4.5-inch pattern identifies the intended hub layout.
A two-piece package provides matching assemblies in the ST205/75R14 size, so buyers can consider it when replacing a pair of trailer wheels. The 14-inch wheel size sets the rim diameter, and the listed 5-by-4.5-inch pattern gives a concrete hub reference for compatibility checks. The 8PR and 105N markings are included for specification comparison. The supplied information does not state a load capacity or inflation pressure, so buyers cannot use this listing alone to verify those figures.
- Two assemblies indicated by Pk2
- ST205/75R14 tire size
- 14-inch white spoke wheel
- 5-by-4.5-inch pattern and 8PR/105N markings
- The supplied specifications do not state load capacity or inflation pressure.
Skip it if you require published load and pressure figures; the eCustomRim ST225/75R15 Load E assembly specifies both.
This package may suit a trailer owner seeking two 14-inch white spoke assemblies with the stated five-on-4.5-inch pattern. Its listed specifications leave load capacity and inflation pressure unresolved, an important limit for load-sensitive replacements.

9. Free Country 15-Inch 6-Lug Assembly
- Material Type: Alloy Steel
- Wheel Size: 15 in
- Rim Size: 15 in
Best for: Six-lug black mod wheel setups.
Why it ranks #9: The ST225/75R15 10-ply tire and 6-by-5.5-inch pattern suit a different hub setup, but the supplied data omits a load rating.
A 10PR, Load Range E ST225/75R15 tire paired with a black mod wheel identifies this set for buyers comparing higher load-range trailer assemblies. Its listed 6-by-5.5-inch pattern distinguishes it from five-lug options, while the 15-inch wheel size narrows the fit comparison to compatible trailer setups.
The ST225/75R15 size and 15-inch wheel give a specific tire and rim diameter reference for comparing against a trailer’s current equipment. A 10PR, Load Range E designation differentiates this tire from lower-load-range choices, while the 6-by-5.5-inch pattern identifies the hub arrangement required. The black mod wheel supplies a defined style. The listing provides no load capacity or inflation pressure, however, so those operating figures cannot be checked from the supplied specifications alone.
- ST225/75R15 tire size
- 10PR, Load Range E designation
- Six-by-5.5-inch bolt pattern
- Black mod wheel
- The supplied specifications do not state load capacity or inflation pressure.
Skip it if you want published load and pressure figures; the eCustomRim ST225/75R15 Load E assembly lists a 2,860-pound rating and 80 PSI limit.
Consider this for a trailer owner needing a 15-inch, six-lug black mod wheel and Load Range E tire. Its missing load and pressure figures are a material boundary when matching the assembly to trailer demands.

10. ROCKMAN 15-Inch Trailer Wheel
- Material Type: Alloy Steel
- Wheel Size: 15 in
- Rim Size: 15 in
Best for: 15-inch silver mod wheel buyers.
Why it ranks #10: This ST205/75R15 8-ply tire-and-wheel listing specifies a 5-by-4.5-inch pattern, but provides no load capacity or package quantity.
An ST205/75R15 radial tire is paired with a silver mod rim, giving trailer owners a specified 15-inch radial option in a five-on-4.5-inch configuration. The listing identifies an 8-ply, Load Range D tire and 107M marking, useful details when comparing this assembly with a trailer’s existing tire requirements.
The ST205/75R15 size and 15-inch rim identify the basic wheel package dimensions, while the stated 5-by-4.5-inch PCD gives buyers a hub-pattern reference. Its radial construction and 8-ply, Load Range D designation help distinguish it from bias-ply alternatives when matching tire type and load range. The silver mod rim provides a specific wheel style. The listed specifications do not state a load capacity or inflation pressure, so those details remain unclear from this product information.
- Radial ST205/75R15 tire
- 8-ply, Load Range D designation
- 5-by-4.5-inch PCD stated
- Silver mod rim
- The listed specifications omit tire load capacity and inflation pressure.
Skip it if you need a stated load rating and inflation limit; the eCustomRim ST205/75R15 Load C assembly lists both values.
Consider this for a trailer owner seeking a 15-inch radial tire and silver mod rim with a five-on-4.5-inch pattern. The unspecified load capacity and pressure make it a poor match when those figures are essential.

View on AmazonAvoiding trailer wheel fitment mismatches
The most important compatibility trap is matching lug count but not the full bolt pattern and hub dimensions. Several picks use five lugs, yet the eCustomRim 15-inch assemblies specify 5 on 4.5 inches and a 3.19-inch center bore, while the eCustomRim 12-inch four-lug set uses 4 on 4 inches and a 2.83-inch bore. The radial eCustomRim 15-inch assembly instead needs 6 on 5.5 inches and lists a 4.25-inch bore.
Confirm the trailer’s existing pattern, center bore, wheel diameter, and tire size before choosing; a matching lug count alone does not establish fit. Also check the product listing carefully when dimensions appear inconsistent: the Garvee set title describes 15-inch rims, while its specifications list a 14-inch rim size.
Resolve that discrepancy with the seller before ordering.
What tire construction and load figures tell you
The listed load rating is a per-tire figure, not a substitute for checking the trailer’s required capacity and recommended inflation. These options span 990 pounds for the 4.80-12 assemblies, 1,360 pounds for the ST175/80D13 set, and 1,820 pounds for several ST205/75D15 bias-ply tires; the radial eCustomRim ST225/75R15 is listed at 2,860 pounds. Do not infer an unlisted capacity: the Free Country and ROCKMAN listings do not provide one in the supplied data.
Construction also differs: many options are bias ply, while the eCustomRim ST225/75R15 explicitly identifies a radial tire. The data does not establish which construction will suit a particular route or wear longer.
Use your trailer documentation and current tire specifications to determine the required rating and size, then compare only products that meet them.
How to Choose Trailer Wheels
Wheel diameter and tire size
Start by matching the tire size and wheel diameter specified for your trailer. The choices here include 12-inch assemblies in 4.80-12, a 13-inch ST175/80D13, a 14-inch ST205/75R14, and several 15-inch sizes. The smaller 12-inch options suit trailers already set up for that size; buyers replacing a 13- or 14-inch assembly should focus on the corresponding size rather than assuming a larger wheel will fit.
The 15-inch choices vary too, including ST205/75D15 and ST225/75R15. Check clearance and the trailer maker’s specifications before changing tire size, since the listings do not establish that different sizes are interchangeable.
Bolt pattern and center bore
Choose a wheel whose complete bolt pattern and center bore match your trailer hub. Most products here use a 5-lug pattern, but that does not mean they all fit the same hub: several specify 5 on 4.5 inches, while the eCustomRim radial 15-inch set uses 6 on 5.5 inches. The 12-inch eCustomRim four-lug assembly is 4 on 4 inches.
Listed center bores also vary, from 2.83 inches on that four-lug set to 3.19 inches on the eCustomRim five-lug 15-inch assemblies and 4.25 inches on the six-lug radial set. Buyers should measure the existing wheel or consult trailer documentation before ordering.
Load rating and tire construction
Select a tire rating that meets or exceeds your trailer’s requirements, and confirm the specified inflation pressure. Listed per-tire capacities range from 990 pounds at 90 PSI for the 4.80-12 options, through 1,360 pounds at 50 PSI for the 13-inch eCustomRim set, to 1,820 pounds at 50 PSI for several ST205/75D15 options. The radial eCustomRim 15-inch assembly lists 2,860 pounds at 80 PSI.
Buyers needing the highest stated capacity should examine that radial option, but only if its 6-lug pattern and size fit. Several other listings omit a capacity in the supplied details, so they require further verification before selection.
Which Trailer Wheel Set Should You Choose?
Choose the eCustomRim 15-Inch Black Assembly if your trailer takes a 5-lug, 4.5-inch wheel and needs the listed ST205/75D15 size; it leads with a stated 1,820-pound rating and pre-mounted assemblies with valve stems. For the same size and pattern in white, choose the eCustomRim 15-Inch White Assembly. If your compatible trailer needs the highest listed tire capacity, the eCustomRim 15-Inch Radial Assembly is rated for 2,860 pounds, but requires a 6-lug, 5.5-inch hub.
For a smaller 13-inch setup, consider the eCustomRim 13-Inch Assembly; for a 12-inch four-lug hub, choose the eCustomRim 12-Inch 4-Lug Assembly. Confirm fitment and required capacity before buying.

Frequently Asked Questions
How do I measure my trailer’s bolt pattern and center bore before ordering?
Count the wheel’s lug holes and measure the bolt pattern using the correct method for that lug count; compare the result with the product listing. Measure the hub’s center diameter and check that it matches the wheel’s center bore. Confirm both measurements, along with wheel diameter, before ordering.
Should I choose bias-ply or radial trailer tires for my towing conditions?
Choose the construction your trailer and towing conditions call for, and verify that it matches the tire type listed for the replacement. In these options, D identifies bias-ply listings and R identifies radial listings. Do not substitute one construction for another without confirming it is suitable for your trailer.
How much load capacity should my replacement trailer tires have?
Choose tires whose combined capacity meets or exceeds the trailer’s required load, while staying within the trailer and wheel limits. Check the tire’s stated rating and the load on each tire rather than relying only on a size match. For example, the listed 15-inch options have different capacities.
What should I check to confirm a wheel assembly will fit my trailer?
Match the wheel diameter, tire size, lug count, bolt pattern, and center bore to your trailer’s requirements. Also confirm the tire construction and load rating. The listed choices include different diameters and patterns, so a similar-looking assembly is not necessarily compatible with your hub.
Are these listings for complete tire-and-wheel assemblies?
The titles describe tire-and-wheel assemblies, and several specify a two-pack or set of two. The editorially verified details state that the eCustomRim 15-inch black assemblies include pre-mounted tires and rims with valve stems. Check the specific listing details to confirm what is included with any other option.
Final Words
Start by matching your trailer’s wheel diameter, bolt pattern, center bore, tire construction, and required load capacity; then compare the compatible choices. For a 5-lug, 4.5-inch setup that takes ST205/75D15 tires, the eCustomRim 15-inch black assembly is the overall pick, with a stated 1,820-pound rating and pre-mounted assemblies with valve stems. Consider the white version for the same size and pattern, or choose another listed size or construction when your trailer requires it.
Confirm fitment before ordering.
