Tire care and maintenance

Warning!
Regularly check the tires for damage. Dam-
aged tires can cause tire inflation pressure
loss. As a result, you could lose control of
your vehicle.
Worn, old tires can cause accidents. If the
tire tread is badly worn, or if the tires have
sustained damage, replace them.
Regularly check the tire inflation pressure
at least once a month. For more informa-
tion on checking tire inflation pressure,
see "Recommended tire inflation pres-
sure" ( page 558).
Tire inspection
Every time you check the tire inflation
G pressure, you should also inspect your
tires for the following:
excessive treadwear ( page 552)
cord or fabric showing through the
tire's rubber
bumps, bulges, cuts, cracks or splits in
the tread or side of the tire
Replace the tire if you find any of the above
conditions.
Make sure you also inspect the spare tire
periodically for condition and inflation.
Spare tires will age and degrade over time
even if never used, and thus should be in-
spected and replaced when necessary.
Tires and wheels
Life of tire
The service life of a tire is dependent upon
varying factors including but not limited to:
Driving style
Tire inflation pressure
Distance driven
Warning!
Tires and spare tire should be replaced after
6 years, regardless of the remaining tread.
