Kenda K353 Bias Trailer Tire - 4.80-12 - Load Range B # AM10060 is rated for a maximum of 65 miles per hour. Provided you stay under 65 you would be at a safe cruising speed.

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.
