SAFETY WARNING
Driving on damaged tires is dangerous. A damaged tire
can suddenly fail causing serious personal injury or death.
Have your tires regularly inspected by a qualied tire
service professional.
You should visually inspect your tires on a regular basis
throughout their life, and you should have your tires
periodically evaluated by a qualied tire service professional
when your vehicle is serviced such as routine maintenance
intervals, oil changes, and tire rotations. In particular, note the
following tips for spotting tire damage:
•
After striking anything unusual in the roadway, have a quali-
ed tire service professional demount the tire and inspect it
for damage. A damaged tire may not show any visible signs
of harm. Yet, the tire may suddenly fail without warning, a
day, a week, or even months later.
•
Inspect your tires for cuts, cracks, splits or bruises in the
tread and sidewall areas. Bumps or bulges may indicate a
separation within the tire body. If you see damage or unusual
condition, have your tire inspected by a qualied tire service
professional. It may be necessary to have it removed from
the wheel for a complete inspection.
•
Inspect your tires for adequate tread depth. When the tire is
worn to the built-in indicators at 2/32 inch (1.6 mm) or less
tread groove depth, or the tire cord or fabric is exposed, the
tire is dangerously worn and must be replaced immediately.
•
Inspect your tires for uneven wear. Wear on one side of the
tread or flat spots in the tread may indicate a problem with
the tire or vehicle. Consult a qualied tire service professional.
• Inspect your wheels also. If you have a bent or cracked
wheel, it must be replaced.
•
Don’t forget to check the spare tire.
Tire Service Life
Make sure your tires, including the spare, continue to be
regularly inspected after 5 years of service to determine
if they can continue in service. Regardless of the tire’s
condition or tread depth, it is recommended that tires more
than 10 years old be taken out of service and replaced with
new tires. REMEMBER TO CHECK YOUR FULL-SIZE OR
TEMPORARY SPARE, ALSO. A spare tire over 10 years old
may look like a new tire, but it should be replaced. See “Tire
Manufacture Date,” the next section in this manual.
The 10 year period after the date of production is not an
indicator of actual service life for any individual tire. Some
tires will need to be replaced before 10 years due to condi-
tions such as punctures, impact damage, improper in
flation,
overloading, tread wear or other conditions involving use
or misuse of the tire. If a tire is worn out or otherwise
