Inflation
--
Tire Pressure
The Tire-Loading Information label, which is on the
driver's door edge, above the door latch, 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. I f your tires
don't have enough air (underinflation), you can
get
the following:
0
Too much flexing
0
Too much heat
0
Tire overloading
0
Bad wear
0
Bad handling
0
Bad fuel economy.

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.
