High-Speed Operation
{CAUTION:
Driving at high speeds, 100 mph (160 km/h)
or higher, puts an additional strain on tires.
Sustained high-speed driving causes
excessive heat build up and can cause
sudden tire failure. You could have a crash
and you or others could be killed. Some
high-speed rated tires require ination
pressure adjustment for high speed
operation. When speed limits and road
conditions are such that a vehicle can
be driven at high speeds, make sure the
tires are rated for high speed operation,
in excellent condition, and set to the
correct cold tire ination pressure for
the vehicle load.If your vehicle has 215/45R18 size tires, they will
require ination pressure adjustment when driving
your vehicle at speeds of 100 mph (160 km/h) or
higher. Set the cold tire ination pressure to
35 psi (241 kPa) for the front and rear tires, when
operating your vehicle at high-speed conditions.
When you end high-speed driving, return the tires to
the cold ination pressure shown on the Tire and
Loading Information label. SeeLoading Your
Vehicle on page 259andInation - Tire Pressure
on page 347.
Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear, rotate your
tires as soon as possible and check wheel
alignment. Also check for damaged tires or wheels.
SeeWhen It Is Time for New Tires on page 351
andWheel Replacement on page 355for
more information.

Temperature – A, B, C
The temperature grades are A (the highest), B,
and C, representing the tire’s resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specied indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure.
The grade C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel than
the minimum required by law.
Warning:The temperature grade for this tire is
established for a tire that is properly inated and
not overloaded. Excessive speed, underination,
or excessive loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned
and balanced carefully at the factory to give you
the longest tire life and best overall performance.
Adjustments to wheel alignment and tire balancing
will not be necessary on a regular basis. However,
if you notice unusual tire wear or your vehicle
pulling to one side or the other, the alignment may
need to be checked. If you notice your vehicle
vibrating when driving on a smooth road, your tires
and wheels may need to be rebalanced. See your
dealer/retailer for proper diagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly
rusted or corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel nuts
should be replaced. If the wheel leaks air, replace
it (except some aluminum wheels, which can
sometimes be repaired). See your dealer/retailer
if any of these conditions exist.
Your dealer/retailer will know the kind of wheel
you need.
