when i worked for sam's club most passager cars we set at 35 big trucks we runabout 65 then dualies we ran the rear at 80 and the fronts at 65. i was trained by michelin and am certified as a master tire techican though them. i've seen car where people wanted us to run the pressure up to 45 when the car calls for 35 then come back to us and wants to know why there tire only lasted 20,000 miles instaead of the 80,000 it was designed for. only thing we didn;t go by the door panel was the ford explorer which called for 26 psi we set then at 35 psi
