Does overinflation cause the same problems as underinflation of tires?
Overinflated tires can create a harsher ride on rough roads and when encountering bumps, cause a distortion in the tread and lead to increased wear in the center of the tread, reducing the contact area with the road. Increased wear due to overinflation will result in replacing your tires sooner than normally expected. Tires should always be properly inflated to the pressure indicated on the door placard and should never be inflated beyond the maximum pressure indicated on the sidewall of the tire.
