Fuel Saving Tips
Inflate More Than You Think
You can safely inflate your tires, in most cases, to a higher pressure. For example, my minivan manual says to inflate to 35psi, but the max pressure on the tire sidewall is 44 psi. I find I can run at 40psi without making the ride too harsh, and I've picked up a couple of MPG. Your mileage (and comfort level) may vary. Never exceed the cold inflation pressure embossed on your tire sidewall.
