Wheel Alignment and Tire Balance

The wheels on your vehicle were aligned at the factory
to give you the longest tire life and best overall
performance.

Proper front wheel alignment must be maintained in
order to ensure efficient steering, good directional
stability, and prevent abnormal tire wear. If you notice
unusual tire wear or your vehicle is pulling one way or
the other, the alignment may need to be reset. If you
notice your vehicle vibrating when driving on a smooth
road, your wheels may need to be balanced.

Tightening the Wheel Nuts

CAUTION:

Wheel nuts that are not tight can work loose. If
all the nuts on a wheel come off, the wheel can
come off the vehicle, causing a crash. All wheel
nuts must be properly tightened. Follow the rules
in this section to be sure they are.

This section lets you know how often to check the
tightness of the wheel nuts on your vehicle and how
tight they must be.

First, use these pictures to decide what kind of wheels
you have.
