ST205/75R15 Trailer Tire and Wheel Assemblies

Every assembly here is an ST205/75R15 trailer tire mounted, balanced and inflated on a 15-inch wheel with a 5 on 4.5 bolt pattern. This is the most common trailer tire and rim combination sold in the U.S., found on single and tandem-axle boat trailers, utility trailers, car haulers and smaller campers.

Choose the load range your trailer needs: C (6-ply), D (8-ply), E (10-ply) or G (14-ply), and a wheel finish from galvanized spoke, white spoke, black or silver modular, or HPD Canyon and HDT aluminum. The tire and wheel are the same parts we sell separately; you skip the mounting and balancing. Lug nuts are sold separately. Orders ship from the U.S. with tracking.

Common questions

Is 205/75R15 with rim the same as ST205/75R15 on a wheel?
Yes. Rim and wheel mean the same part here. Every listing on this page is a tire already mounted on the wheel.

Which load range?
Divide the loaded trailer weight by the number of tires. Under about 1,800 lbs per tire use C, up to about 2,100 use D, up to about 2,400 use E. The 14-ply G version is for heavy single-axle equipment trailers and goes on a wheel rated for its pressure.

How do I confirm 5 on 4.5?
Count five lugs and measure center to center across two studs, skipping one. If it reads 4.5 inches, you are set. See our bolt pattern guide. For a 6-lug trailer, see ST225/75R15 on 6 on 5.5.
