service interval PONTIAC FIREBIRD 1998 Owners Manual

When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be
at
60 psi (420 Pa).
How to Check
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.
Tire Inspection and Rotation
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.
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.
