They will run cooler. In fact, trailer tires should always be inflated to the maximum psi indicated on the tire. This is because trailer tires are built with a thicker sidewall compared to passenger vehicle tires. If a trailer tire is under inflated that thicker sidewall will generate excessive heat and cause tire failure. I have included a link to our informational article on trailer tires for you.
