June 28, 2009What PSI do you all generally run in your tires. I have a 01 250 Ext Cab with the 7.3 and 38 in PJ's. Driving to IN in a week and am trying to button everything up and get the best wear out of my tires as possible. The fronts appear to be wearing on the inside of the tire but it looks overinflated. Right now i'm sitting at i believe 20 psi all around. Thanks for the help. And i know it's probably different for everyone.
