3E-2 WHEELS AND TIRES

GENERAL DESCRIPTION

Replaced wheels or tires must be equivalent to the orig-
inal one in load capacity, specified dimension and
mounting configuration. Improper size or type may af-
fect bearing life, brake performance, speedometer/
odometer calibration, vehicle ground clearance and tire
clearance to the body and chassis.
All models are equipped with metric sized steel belted
radial tires. Correction of tire pressures and driving hab-
its have an important influence on tire life. Heavy corner-
ing, excessively rapid acceleration and unnecessary
sharp braking increase premature and uneven wear.
