The Kenda/Loadstar ST205/75D14 Bias Trailer Tire # AM1ST86 is rated for 65 miles per hour. You would not want to exceed the speed rating on a trailer tire because of heat. Trailer tires are built with a thicker sidewall to handle more vertical load. The thicker sidewall generates more heat compared to passenger vehicle tires, especially if under inflated. That is also why trailer tires should always be inflated to the maximum psi indicated on the tire.

Radial tires run cooler and track better than bias ply tires. For a radial tire in the same size and load range use # AM10234. I have also included a link to our help article on trailer tires for you.
