Where Do You Find the Proper Tire Pressure?
Every new vehicle will have a placard located on the driver-side door jamb behind the seat. It lists the proper inflation pressure for each tire, including the spare tire if your car has one. The numbers on the doorpost are the recommendations from the vehicle’s manufacturer. Please insist your vulcaniser never exceeds 35psi.
If your car does not have a placard, the correct tire pressure information may be found in your owner’s manual or from a dealer’s service department.
The numbers shown represent the correct tire pressure when measured first thing in the morning, when the tires are cold. As you drive, the tires warm up, and pressure will naturally rise a few psi (pounds per square inch).
