(Continued)
• The use of any other tire size or
type may seriously affect ride,
handling, ground clearance, tire
clearance, and speedometer
calibration.
• Driving on worn-out tires is very
hazardous and will reduce braking
effectiveness, steering accuracy,
and raction.
• It is best to replace all four tires on
your vehicle at the same time. If
that is not possible, then replace the
two front or two rear tires as a pair.
Replacing just one tire can
seriously affect vehicle handling.

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.
CAUTION:
A wheel that is not the correct size
may adversely affect wheel and
bearing life, braking and stopping
abilities, handling characteristics,
ground clearance, body-to-tire
clearance, snow chain clearance,
speedometer calibration, headlight
aim and bumper height.
