Tire inflation
Check tire inflation pressure regularly.
A table listing the recommended inflation
pressure for your vehicle can be found on page
83. Tire inflation pressure placards are also
located on the rear edge of the drivers door
(U.S. models), or on the rear edge of the
passenger's door (Canadian models). These
placards indicate the designation of the
factory-mounted tires on your vehicle, as well
as load limits and inflation pressure.
NOTE: The placards shown only indicate
inflation pressure for the tires installed on the
car at the factory.
Use a tire gauge to check the tire inflation
pressure, including the spare, at least once a
month and before long trips. You are
strongly urged to buy a reliable tire pressure
gauge, as automatic service station gauges
may be inaccurate.
Use the recommended cold inflation
pressure for optimum tire performance and
wear.
Under-inflation or over-inflation may cause
uneven treadwear patterns.
When weather temperature changes occur, tire
inflation pressures also change. A 10-degree
temperature drop causes a corresponding drop
of 1 psi (7 kPa) in inflation pressure. Check
your tire pressures frequently and adjust them
to the proper pressure, which can be found on
the vehicles tire information placard or
certification label.
Checking tire pressure
Cold tires
Inflation pressure should be checked when the
tires are cold.
The tires are considered to be cold when
they have the same temperature as the
surrounding (ambient) air.
This temperature is normally reached after the
car has been parked for at least 3 hours.
After driving a distance of approximately 1
mile (1.6 km), the tires are considered to be
hot. If you have to drive farther than this
distance to pump your tire(s), check and record
the tire pressure first and add the appropriate
air pressure when you get to the pump.
WARNING!
- Under-inflation is the most common cause
of tire failure and may result in severe tire
cracking, tread separation, or blowout,
with unexpected loss of vehicle control and
increased risk of injury.
- Under-inflated tires reduce the load
carrying capacity of your vehicle.
