Tire inflation placard

Check tire inflation pressure regularly.

Tables listing the recommended inflation pres- sure for your vehicle can be found on pages 177 and 178. 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- 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.

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
