Whats a good tire pressure for a 2000 Ford Ranger 3.0l Flex Fuel Extended Cab with stock tires? The door panel says 30psi and Ford had that big recall years back on the tires. I don't have Firestones anymore but I feel the truck would run with optimal performance and optimal tire life with a few more pounds like 32psi. What does Ford recommend now in there Rangers? Is that what Ford says to do any way is put a few more pounds in the tire anyway?
