Trailer tires such as the Loadstar ST175/80D13 Bias Trailer Tire # AM1ST77 are actually designed to over-inflate somewhat from their cold PSI rating, which is given to the tire to ensure it performs optimally.

You always want to inflate the tire to the maximum cold PSI, which on this tire is 65. Doing this will give you the best performance, allowing the tire to wear more slowly and give you optimum gas mileage; it will not damage the tire.

We do recommend using radial tires like the Karrier ST175/80R13 Radial Trailer Tire # AM10210 on roadways because they flex more than bias tires and also run cooler overall. I have attached a link to a help article on trailer tires for you to take a look at as well.
