I feel like I've asked a 1000 questions, but why stop at 1000 so here is 1001. I know there have been some posts on tire pressure and the pros/cons of deviating from the recommended tire pressure. My question is one of practicality, gas milage, and safety. How much tire pressure can I safely put in my tires to possibly help out with gas milage? Every time I look at the tires they look "squishy". I've had no problems with how the truck rides so far after just over 1000 miles on it now. So I thought I would bump up the tire pressure a bit for giggles. Any thoughts or suggestions other then, don't deviate from recommended tire pressures?
