Tire Pressure
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
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:
.
Tire overloading and
over-heating which could
lead to a blowout.
.
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

Load Limits on page 9

. 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
pressure of the spare tire.
