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, including the spare, should be removed from service after
10 years from the date of manufacture, regardless of their condition or state of
wear.
Checking Tires
High speed driving
We recommend that you do not drive faster than
the posted speed limits and conditions allow. If you
drive at sustained high speeds (over 118 mph or
190 km/h), adjust the tire pressures as shown below
to avoid excessive heat build up and sudden tire
failure.
6-cylinder models
Tire Size P235/45R18 94V
Pressure 35 psi (240 kPa, 2.4 kgf/cm 2 )
4-cylinder models
Tire Size P225/50R17 93V
Pressure 35 psi (240 kPa, 2.4 kgf/cm 2 )
If you do not, excessive heat can build up and cause
sudden tire failure.
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.
