Tire rotation means moving the wheels
to a different position, with respect to
the vehicle. During rotation, inspect tires
for correct balance.
The single wheel will therefore operate
on a different axle and, where possible,
on the opposite side of the vehicle.
Note:
Rotate tires periodically. Irregular tire
wear is dangerous. To equalize tread
wear for maintaining good
performance in handling and braking,
rotate the tires every 6,200 miles
(10,000 km), or sooner if irregular wear
develops.
To equalize tread wear, rotate the
tires every 7,500 miles (12,000 km) at
the latest or sooner if irregular wear
develops. FCA recommends to rotate
every 5,000 miles (8,000 km) to help
increase tire life and distribute wear
more evenly.
Because your vehicle is not
equipped with a spare tire, you cannot
do a tire rotation safely with the jack
that may come with your vehicle if so
equipped. Contact an authorized
dealer for tire rotation.
Also, inspect them for uneven wear and
damage. Abnormal wear is usually
caused by one or a combination of the
following:
Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, inflate all tire pressures to
specification and inspect the wheel nuts
for tightness.
With Tire Pressure Monitor System
(TPMS)
The TPM system must be initialized
after adjusting the tire pressure, to
make the system operate normally.
Refer to “Tire Pressure Monitoring
System” in “Safety” for further
information.
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern only from front to rear, not from
side to side. Tire performance will be
reduced if rotated from side to side.

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
