If your tires have too much air (overinflation),
you can get the following:
D Unusual wear

D Bad handling

D Rough ride

D Needless damage from road hazards.

Check your tires once a month or more. Also, check the
tire pressure of the spare tire.

Use a good quality pocket

-

type gage to check tire

pressure. You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.

Be sure to put the valve caps back on the valve 
stems. They help prevent leaks by keeping out dirt 
and moisture.

Tires should be rotated every 6,000 to 8,000 miles 
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later in this section for more
information. Make sure the spare tire is stored securely.
Push, pull, and then try to rotate or turn the tire. If it
moves, use the ratchet to tighten the cable. See “Storing
a Flat or Spare Tire and Tools” in the Index. If your
vehicle has dual rear wheels, also see “Dual Tire
Operation” later in this section.

The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.
