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
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 Vehicle
Load Limits
on page 8‑12
.
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. Do not forget to check
the compact spare tire, if the
vehicle has one. The compact
spare should be at 60 psi
(420 kPa). For additional
information regarding the
compact spare tire, see
