The best 15-inch tire and wheel package depends on your trailer’s required tire size, load rating, and wheel bolt pattern. For a radial setup, the eCustomRim ST205/75R15 package offers Load Range D capacity; for a bias-ply option, consider the eCustomRim ST205/75D15 assembly. Garvee and GarveeTech provide two-pack Load Range C assemblies, while ROCKMAN is an option for buyers seeking an 8-ply ST205/75R15 tire. Compare the specifications below and confirm fitment before ordering.

eCustomRim Radial Trailer Tire Package
This two-pack pairs ST205/75R15 radial tires with 15 x 6-inch rims. The listed tire rating is Load Range D, with a maximum load of 2,150 pounds and maximum pressure of 65 PSI. The assembly has a 5-lug, 4.5-inch bolt pattern and a 3.19-inch center bore. The listing describes the tire, wheel, and valve stem as DOT-approved and states that the package includes a six-year manufacturer’s warranty with roadside assistance.
Best for: Trailer owners whose specifications call for this radial size, Load Range D, and bolt pattern. Its stated capacity is higher than the Load Range C assemblies in this guide. Check first: Confirm the trailer’s approved tire size, wheel dimensions, and pressure requirements; do not select it by load rating alone.
eCustomRim Bias-Ply Trailer Assembly
This two-pack is built around ST205/75D15 bias-ply tires with Load Range C. Each tire is listed with a maximum load of 1,820 pounds and maximum pressure of 50 PSI. The black 15 x 5-inch rims have a 5-lug, 4.5-inch bolt pattern and a 3.19-inch center bore. The listed overall tire diameter is 27.2 inches. The product description says the tire, wheel, and valve stem are DOT-approved and mentions a two-year manufacturer’s warranty with roadside assistance.
Best for: Buyers who need a bias-ply ST205/75D15 assembly and whose trailer accepts the narrower 15 x 5-inch rim. Check first: Its Load Range C rating and 50 PSI maximum may not meet every trailer’s requirements.
Garvee ST205/75D15 Two-Pack
Garvee’s package includes two ST205/75D15 bias-ply tires and black steel rims measuring 15 x 6 inches. The tires are described as 6-ply, Load Range C, with a maximum load of 1,820 pounds and maximum pressure of 50 PSI. The wheels use a 5-lug, 4.5-inch bolt pattern. Garvee describes the bias-ply construction as nylon cords in a crisscross pattern, intended to provide flexible sidewalls and stable traction on uneven terrain.
Best for: Owners of compatible utility, boat, or camping trailers who want two assemblies with 15 x 6-inch rims. Check first: The product’s stated capacity is 1,820 pounds per tire, and its maximum pressure is 50 PSI; match both to your trailer’s specifications.
GarveeTech White-Spoke Wheel Set
This set of two includes ST205/75D15 bias-ply tires with Load Range C and 6-ply construction. The listing specifies a maximum load of 1,820 pounds at 50 PSI. The tires come mounted on 15-inch white spoke wheels with a 5-lug, 4.5-inch bolt pattern. The product description also lists nylon cord layers and double steel belts and describes the assemblies as ready to install.
Best for: Buyers who need this tire size and bolt pattern and prefer white spoke wheels over black or silver mod-style rims. Check first: The listed wheel diameter and bolt pattern do not replace the need to verify rim width, center bore, and load requirements for your trailer.
ROCKMAN Load Range D Assembly
ROCKMAN’s ST205/75R15 package is listed as an 8-ply, Load Range D assembly on a silver mod rim. The listed specifications include a 107 load index, M speed rating, and 5 x 4.5-inch PCD. The manufacturer describes a full nylon cap ply overlay across the tread and an 8 mm tread depth. These details distinguish it from the Load Range C bias-ply options, but the listing does not provide the same complete wheel measurements as some other packages here.
Best for: Buyers seeking an ST205/75R15 Load Range D option with a 5 x 4.5-inch pattern. Check first: Confirm the rim width, center bore, and tire load capacity with the seller or product documentation before purchase, since those details are not included in the supplied specifications.
Buying Guide: How To Choose A 15-Inch Tire And Wheel Package
Does the tire size match your current setup?
Read the full tire marking, not just the 15-inch wheel diameter. ST205/75D15 identifies a bias-ply trailer tire, while ST205/75R15 identifies a radial trailer tire. Do not assume the two designs are interchangeable. Check the trailer placard, owner’s manual, or existing tire specifications before choosing.
What load range and pressure do you need?
Compare the tire’s stated load capacity and maximum pressure with the trailer maker’s requirements and the load each tire will carry. The options listed here include Load Range C tires rated up to 1,820 pounds at 50 PSI and Load Range D choices, including one listed at 2,150 pounds and 65 PSI. Never exceed the tire’s stated limits, and use the recommended operating pressure.
Will the wheel fit the hub?
Verify the bolt pattern, rim diameter and width, and center bore. Several packages list a 5-lug, 4.5-inch pattern, but that does not establish that every wheel will fit your trailer. Also check clearance around brakes, suspension parts, and the fender.
Should you choose radial or bias ply?
Choose the construction specified for your trailer or recommended by its manufacturer. These product listings describe bias-ply options as suitable for their intended trailer use and emphasize radial construction on other assemblies. Compare the complete tire designation and avoid mixing types unless your trailer manufacturer allows it.
Frequently Asked Questions
Are 15-inch trailer tires all the same size?
No. The 15-inch figure refers to the wheel diameter. Tire width, aspect ratio, construction, load range, and overall diameter also matter for fit and safe operation.
Can I use a 15-inch tire with any 15-inch rim?
No. Tire and rim width must be compatible, and the wheel must match the trailer’s bolt pattern, center bore, and clearance requirements.
What does ST205/75R15 mean?
It identifies a special trailer tire with a 205 mm nominal section width, a 75 aspect ratio, radial construction, and a 15-inch rim diameter. The D in ST205/75D15 indicates bias-ply construction.
Is Load Range D always better than Load Range C?
Not automatically. Select the load range that meets the trailer manufacturer’s requirements. A higher rating does not correct an incorrect tire size, pressure, or wheel fitment.
Should I replace trailer tires in pairs?
Replacing tires in pairs on the same axle can help maintain consistent size and construction. Follow the trailer manufacturer’s guidance and inspect all tires for condition and matching specifications.
