uuChecking and Maintaining TiresuWear Indicators
Maintenance
Wear Indicators
The groove where the wear indicator is
located is 1/16 inch (1.6 mm) shallower than
elsewhere on the tire. If the tread has worn so
that the indicator is exposed, replace the tire.
Worn out tires have poor traction on wet
roads.
Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pressure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).
In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires should be removed from service after 10 years from the date of
manufacture, regardless of their condition or state of wear.
1Checking Tires
High speed driving
We recommend that you do not drive on public roads
faster than the posted speed limits and conditions
allow. If you intend to drive at sustained high speeds
(over 168 mph or 270 km/h), such as at a track or
other closed course venue, adjust the cold tire
pressures as shown below to avoid excessive heat
build up and sudden tire failure.
