Tire inflation

Tire inflation placards on U.S. models
Check tire inflation pressure regularly.
Tables listing the recommended inflation pres-
sure for your vehicle can be found on pages
170 and 171. A tire inflation pressure placard
is also located on the driver's side B-pillar (the
structural member at the side of the vehicle, at
the rear of the driver's door opening). This plac-
ard indicates the designation of the factory-
07
mounted 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.
