A 225/75-15 trailer tire will fit on a few different size 15" wheels. The most common size wheel for the above tire size is a 15" x 6" wheel like the Lionshead Steel Modular Trailer Wheel part # LHHA312. The Lionshead Steel Trailer Wheel has a 6 on 5-1/2" bolt pattern with a 2,850 lbs capacity. The valve stem and cap are included with the wheel.

I have also included a list of all our 15" x 6" wheels with a 6 on 5-1/2" bolt pattern for you.
