Inflation-Tire Pressure
The Certification/Tire label, which is on the driver's door lock pillar, shows the
correct inflation pressures for your tires, when they're cold. "Cold'' means your
vehicle has been sitting for at least three hours or driven no more than a
mile.

When to Check: Check your tires once a month or more. Don't forget your
compact spare tire (if
so equipped). It should be at
60 psi (420 kPa).
How to Check: Use a good quality pocket-type gage to check tire pressure.
Simply looking at the tires will not tell you the pressure, especially if you
have radial tires-which may l'ook properly inflated even if they're
underinflated.
If your tires have valve caps, be sure to put them back on. They help
prevent leaks by keeping out dirt and moisture.
Ere lnspection and Rotation
To make your tires last longer, have them inspected and rotated at the
mileages recommended in the Maintenance Schedule. See Scheduled
Maintenance Services in the Index.
