Tires and Wheels
Tire Condition
Inspect tires often-every 2,000 miles or so-for visible signs
of underinflation and uneven wear, which may indicate need
for front-end alignment, tire rotation, or wheel balancing. Tire
pressure should be checked and adjusted, if necessary at
least once a month.
Tread Still Good Tread Worn Out
Wide-Tread and Radial-Ply Tires
These types of tires must be installed on the vehicle In com­
plete sets, and be used only when there is adequate clear­
ance. (Wagoneer and Cherokee vehicles with radial tires
require front sway bar.)
WARNING: Radial or wide-tread tires must not be mixed
with conventional bias-ply tires, or the fiberglass belted "78"
ser,es t,res
as
this could result in dangerous steering prob-
fems. Application of special tires may result in different com­
pound stresses and thus m reduced gross toad ratings.
Mud and Snow Tires
All Jeep vehicles and especially tho•• with Quadra-Trac
dnve, must be equipped with the same size tires of equal
circumference on all four wheels Therefore, should mud and
snow tires be required-they must be installed on all four
wheels.
Sustained speeds over 75 mph for one hour or more are not
recommended for mud and snow tires.

Aftermarket Wheels and Tires
Certain combinations of aftermarket replacement wheels and
ttres can increase the tread measurement and change steer­
ing and suspension geometry. This can result 1n a dangerous
deterioration of vehicle steering capab11tty and possibly in­
duce overloading and unnecessary wear and tear of steering
and suspension components. Therefore, use only those
wheel and tire combinations approved by Jeep Corporation
as standard or optional equipment.
WARNING:
A// Jeep vehicles must be equipped with the
same size t,res of equal circumference on all four wheels.
