Sutong ASR1205 ST225/75R15 Trailer Tire Assembly 8 Ply

Product Description

The SUTONG TIRE RESOURCES INC ASR1205 is a complete trailer tire and wheel assembly built around an ST225/75R15 tire mounted on a 15 inch by 6 inch white steel wheel. The tire is rated 8 ply (Load Range D) and carries a maximum load rating of 2,540 pounds per assembly. The eight-spoke white wheel uses a 6-lug bolt pattern with a 5.5 inch bolt circle, making it a bolt-on solution for boat trailers, utility trailers, and cargo trailers. This assembly ships ready to mount, reducing shop time for trailer service technicians and fleet maintenance crews.

This assembly is suited for single-axle and tandem-axle trailer applications in both residential and light commercial service. It is designed for highway towing use where load stability, tread wear, and water evacuation are priorities. The ST (Special Trailer) tire designation means it is engineered specifically for trailer axles, not tow vehicles. Typical installation scenarios include replacing worn or damaged assemblies on boat trailers, enclosed cargo trailers, and flatbed utility trailers requiring a 6-lug 5.5 inch bolt pattern fitment.

Installation Notes

Installation of trailer wheel assemblies should follow the trailer manufacturer torque sequence and the applicable DOT tire mounting guidelines. Verify the lug nut seat type (conical vs. ball seat) matches the wheel before mounting. Chock the trailer, ensure it is properly supported on stands, and confirm the valve stem and inflation are set to the trailer manufacturer specification before returning to service. Inspect the wheel bearing and hub condition any time a tire assembly is changed.
