Tire inflation placard
Check tire inflation pressure regularly.
A table listing the recommended inflation pres-
sure for your vehicle can be found on page
177. A tire inflation pressure placard is also
located on the driver's side B-pillar (the struc-
tural member at the side of the vehicle, at the
rear of the driver's door opening). This placard
indicates the designation of the factory-moun-
ted tires on your vehicle, as well as load limits
and inflation pressure.
NOTE
The placards shown indicate inflation pres-
sure for the tires installed on the vehicle at
the factory only.
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 pres-
sure gauge, as automatic service station
gauges may be inaccurate.
Use the recommended cold inflation pres-
sure for optimum tire performance and
wear.
Under-inflation or over-inflation may cause
uneven treadwear patterns.
WARNING
Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation,
or "blow-out," with unexpected loss of
vehicle control and increased risk of
injury.
Under-inflated tires reduce the load car-
rying capacity of your vehicle.
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 vehicle's tire information placard or certifi-
cation label.
Checking tire pressure
A certain amount of air seepage from the tires
occurs naturally and tire pressure fluctuates
with seasonal changes in temperature. Always
check tire pressure regularly.
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 sur-
rounding (ambient) air.
This temperature is normally reached after the
vehicle 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 pres-
sure when you get to the pump.
If checking tire pressure when the tire is hot,
never "bleed" or reduce air pressure. The tires
are hot from driving and it is normal for pres-
sures to increase above recommended cold
