Tires

Inflation - Tire Pressure
Tires need the correct amount of air pressure to operate
effectively.
Notice: Do not let anyone tell you that
under-inflation or over-inflation is all right. It is
not. If your tires do not have enough air
(under-inflation), you can get the following:
•
Too much flexing
•
Too much heat
•
Tire overloading
•
Premature or irregular wear
•
Poor handling
•
Reduced fuel economy
If your tires have too much air (over-inflation),
you can get the following:
•
Unusual wear
•
Poor handling
•
Rough ride
•
Needless damage from road hazards
5-24
A vehicle specific Tire and Loading Information label is
attached to your vehicle. This label shows your vehicle's
original equipment tires and the correct inflation
pressures for your tires when they are cold. The
recommended cold tire inflation pressure, shown on the
label, is the minimum amount of air pressure needed to
support your vehicle's maximum load carrying capacity.
For additional information regarding how much weight
your vehicle can carry, and an example of the Tire and
Loading Information label, see "Loading Your Vehicle" in
the Index of the owner manual. How you load your
vehicle affects vehicle handling and ride comfort. Never
load your vehicle with more weight than it was designed
to carry.
When to Check
Check your tires once a month or more.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly inflated
simply by looking at them. Radial tires may look properly
inflated even when they're underinflated. Check the tire's
inflation pressure when the tires are cold. Cold means
your vehicle has been sitting for at least three hours or
driven no more than 1 mile (1.6 km).
