Check Pressure Once a Month

It’s possible for a passenger tire initially inflated to 35 psi (pounds per square inch) to lose 1 psi each month.

Be sure to properly check all four tires cold once a month and before a long trip.

Whether you have a full-size or mini spare, make sure that it is properly inflated as well.

Recommended Pressure

If you don’t know the proper inflation air pressure for your tires, what do you do?

Easy. Check at one of the following places on your vehicle:

• In the vehicle owners manual.
• On the vehicle’s door jamb. (Often, a vehicle information placard is located on the door jamb along with the recommended tire inflation pressure.)
• Inside the fuel hatch filler flap. (In some vehicles.)
• The glove compartment door. (In some vehicles.) But NOT on the tire. The inflation pressure shown on the tire sidewall is only the maximum tire inflation pressure.

How to Properly Check Tire Pressure

• Beware of public pressure gauges at gas stations. They are often abused and unreliable.
• Purchase a good pressure gauge and check it for accuracy with your Michelin retailer.
• Check your tires cold – before you’ve driven even one mile or at least three hours after the vehicle has been stopped.

Inflation Tips

• Air expands when it’s hot and contracts when it’s cold
• It’s best to inflate your tires in the morning before the day’s heat.
