Tire inflation placard
Tire inflation
Check tire inflation pressure regularly.
See the tire inflation table on page 299. 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 placard indicates the des-
ignation of the factory-mounted tires on your
vehicle, as well as load limits and inflation pres-
sure.
NOTE
• The placards shown indicate inflation
pressure for the tires installed on the
vehicle at the factory only.
• A certain amount of air seepage from
the tires occurs naturally and tire pres-
sure fluctuates with seasonal changes
in temperature. Always check tire pres-
sure regularly.
• 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
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.
