The wheels originally equipped on the vehicle will
provide optimum life up to the maximum load and inflation
pressures shown in the Wheel Code and Limits Chart.
M a x im u m loads, m a x im u m inflation pressures, wheel
identification codes, and wheel sizes are stamped on each
wheel. Service tested and approved wheels are available
from service. W hen obtaining wheels for any reason from
any o ther source, the rep lacem ent wheels should be equal
in load capacity, inflation p re ssu re capacity, diam eter,

A wheel of the wrong size or type may adversely affect
load carrying capacity, wheel and bearing life, brake
cooling, speed om eter/od om eter
ability, h eadlight aim, bum per height, vehicle ground
clearance, and tire clearance to the body and chassis.
Replacement with "used" wheels is not advised: they may
have been subjected to harsh treatm ent or very high mileage
and could fail without warning.
T he use of wheels a n d /o r tires with higher load
carrying limits than originally equipped on the vehicle does
not in itself increase the G A W R or the G V W R of the
vehicle.
