Only trailers should wear the Power King Towmax STR II, a highway-terrain, all-season trailer tire. Its construction does not suit the weight and driving style of light trucks, so it should never be mounted on one.
The ST225/75R15 light truck size is rated 117/112L for load and speed, load range E. It offers an 80 psi maximum inflation pressure and an overall diameter of about 28.3 inches.
