With a well inflated tire, you may pick up a few MPG but going too far up reduces traction and ride comfort. With these tires (Michelin), at 35 pounds of nitrogen, I get the traction that was missing on the Dunlops and all the other features that 29-30 pounds of air would give me with the Dunlops, but better.If you over inflate, you will wear the center of the tires out faster.

At 29 pounds of air you should get a better ride and better traction but tire life will go down.On the original Dunlops, with 35-38 pounds, I got 60K miles and could have gone to 65K before buying the Michelin M/S 2's. Toyota wants to give you a compromise between a good ride, traction, hauling capacity, safety, gas mileage and tire life (maybe). The new tires (Hankook Dynapro ATm) have a 44 psi max. Click to expand.The door jam info is for the stock tires (BFG Rugged Trails or whatever).They are a 35 psi max tire, and the Toyota recommended 29 front/ 32 rear is perfect for that tire.When I change to both a different tire (and a different size), that door jam suggestion has no more use.
