Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are im-
properly inflated or on slippery road
surfaces. Tires should be replaced
when tread wear indicators appear.
To reduce the possibility of losing
control, slow down whenever there is
rain, snow or ice on the road.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn un-
evenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should al-
ways be rebalanced if it is removed
from the wheel.
Tire sidewall labeling
This information identifies and de-
scribes the fundamental characteris-
tics of the tire and also provides the
tire identification number (TIN) for
safety standard certification. The TIN
can be used to identify the tire in case
of a recall.
