WHEELS AND TYRES
12.4.1 Inspection and Adjustment Procedure
The tire pressure should be checked and adjusted, as well as
inspected for signs of tire wear or visible damage, at least once a
month. Use a good quality pressure gauge to check tire pressure.
Do not make a visual judgement when determining proper inflation.
Radial tires may look properly inflated even when they are
underinflated. At the same time, each tire should be inspected for
signs of tire wear or visible damage.
Inflation pressures specified on the placard are always cold tire
inflation pressures. Cold tire inflation pressure is defined as the tire
pressure after the vehicle has not been driven for at least three
hours, or driven less than 1 km after a three-hour period. Check tire
pressures more often if subject to a wide range of outdoor
temperatures, as tire pressures vary with temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per 7°C of air
temperature change. Keep this in mind when checking tire
pressure inside a garage, especially in the winter.
When it was new, the spare tire in your vehicle was fully inflated.
However, a spare tire can lose pressure over time. In order to avoid
being stranded, check the spare tire air pressure frequently.
12.4.2 Inflating Your Tires
Safe operation of your vehicle requires that your tires are properly
inflated. Remember that a tire can lose up to half of its air pressure
without appearing flat.
12-4
At least once a month or before long trips, inspect each tire and
check the tire pressure with a tire gauge (including spare tire).
Inflate all tires to the recommended inflation pressure.
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.
Always inflate your tires to the recommended pressure even if it is
less than the maximum inflation pressure information found on the
tire. The recommended tire inflation pressure is found on the Tire
Label which is located on the front passenger side inner B-pillar.
Failure to follow the tire pressure recommendations can cause
uneven tread wear patterns and adversely affect the way your
vehicle handles.
If you overfill the tire, release air by pushing the metal stem in
the center of the valve. Then recheck the pressure.
