Inflation
--
Tire Pressure
The Tie-Loading Information label, which is on the
rear edge of the driver's door, 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
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 P a ) .
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 d i r t and moisture.
