Tire Pressure

Tires need the correct amount of
air pressure to operate
effectively.

Notice:

Neither tire

underinflation nor
overinflation is good.
Underinflated tires, or tires
that do not have enough air,
can result in:

.

Tire overloading and
overheating which could
lead to a blowout.

.

Premature or
irregular wear.

.

Poor handling.

.

Reduced fuel economy.

Overinflated tires, or tires that
have too much air, can
result in:

.

Unusual wear.

.

Poor handling.

.

Rough ride.

.

Needless damage from
road hazards.

The Tire and Loading
Information label on the vehicle
indicates the original equipment
tires and the correct cold tire
inflation pressures. The
recommended pressure is the
minimum air pressure needed to
support the vehicle's maximum
load carrying capacity.

For additional information
regarding how much weight
the vehicle can carry, and an
example of the Tire and Loading
Information label, see

Vehicle

Load Limits on page 9

. How

the vehicle is loaded affects

vehicle handling and ride
comfort. Never load the vehicle
with more weight than it was
designed to carry.

When to Check

Check the tires once a month or
more. Do not forget the compact
spare tire, if the vehicle has one.
The compact spare should be at
420 kPa (60 psi). For additional
information regarding the
compact spare tire, see

Compact Spare Tire on
page 10

.

How to Check

Use a good quality pocket-type
gauge to check tire pressure.
Proper tire inflation cannot be
determined by looking at the tire.
Check the tire inflation pressure
when the tires are cold, meaning
the vehicle has not been driven
for at least three hours or no
more than 1.6 km (1 mi).
