Inflation
--
Tire Pressure
The Tire-Loading Information label, which is
on the
inside of the trunk lid 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 1 mile (1.6
km).
NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not. If your tires
don't have enough
air
(underinflation), you can
get the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued)
NOTICE: (Continued)
If
your tires have too much
air
(overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
0
Needless damage from road hazards.
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 Wa).
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.
