Article: You can find this in the owner's manual, on a sticker inside the driver-side door jamb, or in the glove compartment. It may be the same for all four tires, or the front and rear tires may be differentit differs by model. Normally, it will be in the range of 28 to 36 psi (pounds per square inch) or 195 to 250 kPa (kilopascals). You can also find the maximum tire pressure on the tires themselves, but use this only if you can't find the vehicle's recommended numbers. "Maximum" doesn't necessarily translate to "best." A good rule of thumb is to set the tires to 32 psi. Then find the proper pressure and correct as needed. Warm air expands, and will give you a false reading of greater pressure.

Find the recommended pressure. Check the tires when cool.
