Customer Information and Reporting Safety Defects
Tire Information (U.S.A.)
NOTE
Tires degrade over time, even when
they are not being used on the road. It
is recommended that tires generally be
replaced when they are 6 years or
older. Heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process. You
should replace the spare tire when you
replace the other road tires due to the
aging of the spare tire. The period in
which the tire was manufactured (both
week and year) is indicated by a 4-digit
number.
Refer to Tire Labeling on page 8-23.

▼ Safety Practices
The way you drive has a great deal to
do with your tire mileage and safety.
So cultivate good driving habits for
your own benefit.
Observe posted speed limits and

drive at speeds that are safe for the
existing weather conditions
Avoid fast starts, stops and turns

Avoid potholes and objects on the

road
Do not run over curbs or hit the tire

against the curb when parking
CAUTION
If you feel a sudden vibration or ride
disturbance while driving or you
suspect your tire or vehicle has been
damaged, immediately reduce your
speed. Drive with caution until you can
safely pull off the road. Stop and
inspect the tire for damage. If the tire
is under-inflated or damaged, deflate
it, remove the tire and rim and replace
it with your spare tire. If you cannot
detect a cause, have the vehicle towed
to the nearest vehicle or tire dealer to
have the vehicle inspected.
