TIRE CHAINS AND TRACTION DEVICES —
SRT
Due to limited clearance, tire chains or traction
devices are not recommended.
TIRE ROTATION RECOMMENDATIONS —
N
ON-SRT
Tires on the front and rear axles of vehicles
operate at different loads and perform different
steering, driving, and braking functions. For
these reasons, they wear at unequal rates.
These effects can be reduced by timely rotation
of tires. The benefits of rotation are especially
worthwhile with aggressive tread designs such
as those on all season type tires. Rotation will
increase tread life, help to maintain mud, snow
and wet traction levels, and contribute to a
smooth, quiet ride.
Refer to “Scheduled Servicing” in “Servicing
And Maintenance” for the proper maintenance
intervals. The reasons for any rapid or unusual wear
should be corrected prior to rotation being
performed.
The suggested rotation method is the “rearward
cross” shown in the following diagram. This
rotation pattern does not apply to some
directional tires that must not be reversed.

Tire Rotation — Same Tire Size On Front And
Rear Axle
The suggested rotation method for vehicles
equipped with non directional three season and
all season tires is the “forward cross” as shown
in the following diagram.

CAUTION!
Damage to the vehicle may result if tire

TIRE ROTATION—DIFFERENT TIRE SIZE

N FRONT AND REAR AXLE
The suggested rotation method is the
“side-to-side” as shown in the following
diagram. This method is required due to
different size tires on the front and rear of the
vehicle.

DEPARTMENT OF TRANSPORTATION
UNIFORM TIRE QUALITY GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by the
tire's manufacturer in each category is
shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform
to Federal safety requirements in
addition to these grades.
TREADWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one and one-half times as well on
the government course as a tire graded
100. The relative performance of tires
depends upon the actual conditions of
their use, however, and may depart significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
TRACTION GRADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These grades
represent the tire's ability to stop on wet
pavement, as measured under
controlled conditions on specified
government test surfaces of asphalt and
concrete. A tire marked C may have poor
traction performance.
WARNING!
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.

**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway).
NOTE:
If in doubt about the correct tightness, have
them checked with a torque wrench by an
authorized dealer or service station.
After 25 miles (40 km), check the lug nut/bolt torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.

WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully
until the vehicle has been lowered. Failure to
follow this warning may result in personal
injury.
