GENERAL
Jeep vehicles are equipped with American and metric
size, tubeless-type, pneumatic tires available in load
ranges SL, B, C, and D. Standard equipment tires are of
bias-ply or bias-belted construction. Radial-ply tires are
available as an option on most models.
Standard equipment wheels are safety rim, drop cen
ter-types constructed entirely of steel. Optional wheels,
which are available on most models, consist of forged
aluminum wheels, wide rim spoke-type sport wheels,
and chrome-plated styled steel wheels.
Original equipment wheels and tires are tested and
selected to provide the best all around performance for
normal operation. To obtain optimum wheel/tire per
formance, tire inflation pressures must be maintained
at recommended levels and wheel/tire condition should
be checked regularly. This is especially important on
vehicles equipped with the Quadra-Trac full-time four-
wheel drive transfer case.
TIRE CONSTRUCTION
Three types of tire construction are currently in use.
They are referred to as bias-ply, bias-belted, and radial-
ply construction. The description for each construction-
type is derived from the method used to position the tire
cord plies in relation to the tread centerline.
Bias-Ply Construction
Bias-ply tires are constructed with the body cord plies
extending from bead-to-bead and at an angle to the

Bias-Belted Construction
Bias-belted tires are constructed basically the sa:
bias-ply tires. However, in addition to the angled
cord plies, they also have belts that encircle the
These belts are located under the tire tread and e?
from tread shoulder to tread shoulder (fig. 2H-1).
Radial-Ply Construction
Radial-ply tires, like bias-belted tires, also have
under the tread which encircle the tire and extend
tread shoulder to tread shoulder. However, these
