Thanks for the opinions. The tires are 225/75r15 load range D with a max pressure of 65 psi. My question about over pressurizing the tires came from the shop that mounted the Goodyear. My wheels are also made in China and have a max pressure of 65 psi. Today I ordered some Dexstar made in America steel wheels with max pressure of 80 psi. The local tire warehouse we use at work has load range E Maxxis tires in stock and I will buy some on Monday. Hopefully this will solve my problem. I do not tow over 65, usually right at 60.
