10-44 Vehicle Care
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 9‑10.
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 cold
compact spare should be at
420 kPa (60 psi). For additional
information regarding the
compact spare tire, see
Compact Spare Tire on
page 10‑77.
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
