tow vehicle tire pressure w/hitch

I have run 10-15 psi over Max sidewall rating on my truck tires for hundreds of thousands of miles. As long as the tires wear even no damage done. Stiffer side wall means less sway, tires last longer and better fuel economy, just have to deal with the stiffer ride.

Buy a good quality tire and you'll be surprised what they can withstand.

#1 cause of tire failure is low pressure.
