Haynes Tech Tips - Tire Pressure
How much tire pressure?
Many people think they should inflate their tires to the pressure that’s molded into the side of the tire. This is not the case. Vehicle manufacturers determine proper tire pressure based upon the vehicle’s weight distribution.
As a matter of safety, be sure to always use the manufacturer’s recommended tire pressure, which is listed in the owner’s manual and also on a sticker that’s attached to the driver’s side door jamb.
