Use the recommended cold inflation pressure for optimum tire

performance and wear. Under-inflation or over-inflation may cause

uneven treadwear patterns.

Under-inflation is the most common cause of tire failures and

may result in severe tire cracking, tread separation or ⬙blowout⬙,

with unexpected loss of vehicle control and increased risk of injury.

Under-inflation increases sidewall flexing and rolling resistance,

resulting in heat buildup and internal damage to the tire. It also may

result in unnecessary tire stress, irregular wear, loss of vehicle control

and accidents. A tire can lose up to half of its air pressure and not

appear to be flat!

When weather temperature changes occur, tire inflation pressures also

change. A 6° C (10° F) temperature change can cause a corresponding

drop of 7 kPa (1 psi) in inflation pressure. Check your tire pressures

frequently and adjust them to the proper pressure which can be found

on the tire label or certification label.

If you are checking tire pressure when the tire is hot, (i.e. driven more

than 1.6 km [1mile]), never “bleed” or reduce air pressure. The tires are

hot from driving and it is normal for pressures to increase above

recommended cold pressures. A hot tire at or below recommended cold

inflation pressure could be significantly under-inflated.

To check the pressure in your tire(s):

1. Make sure the tires are cool, meaning they are not hot from driving

even a mile.

Note: If you have to drive a distance to get air for your tire(s), check

and record the tire pressure first and add the appropriate air pressure

when you get to the pump. It is normal for tires to heat up and the air

pressure inside to go up as you drive. Never “bleed” or reduce air

pressure when tires are hot.

2. Remove the cap from the valve on one tire, then firmly press the tire

gauge onto the valve.

3. Add air to reach the recommended air pressure

Note: If you overfill the tire, release air by pushing on the metal stem in

the center of the valve. Then recheck the pressure with your tire gauge.

4. Replace the valve cap.

5. Repeat this procedure for each tire, including the spare.

Note: Some spare tires require higher inflation pressure than the other

tires. Check the tire label on the B pillar or the driver’s door for the

recommended spare tire pressure.
