A radial tire is going to be better for highways. They run cooler and track better than bias ply tires. You can use tire # AM10130. This is a 145/R12 tire, load range D, rated for 1,220 pounds at 65 psi. The tires have a speed rating of 65 miles per hour.

Trailer tires should always be inflated to the maximum psi indicated on the tire sidewall. This is because trailer tires are built with a thicker sidewall than passenger vehicle tires to handle more vertical load. If under inflated the thicker sidewall generates excessive heat and can lead to failure.
