WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion,
the wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or they may cause loss of handling control. WHEEL SELECTION
When replacing wheels, care should
be taken to ensure that the wheels are
replaced by ones with the same load
capacity, diameter, rim width, and off-set.
This m
ust be observed on compact spare
tires, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may ad-
versely affect handling, wheel and bear-
ing life, brake cooling, speedometer/
odometer calibration, stopping ability,
headlight aim, bumper height, vehicle
ground clearance, and tire or snow chain clearance to the body and chassis. Replacement
with used wheels is not rec-
ommended as they may have been sub- jected to rough treatment or high mileageand could fail without warning. Also, bent
wheels which have been straightened
may have structural damage and there-
fore should not be used. Never use an in-
ner tube in a leaking wheel which is de-
signed for a tubeless tire.
After driving your vehicle the first 1600
km (1000 miles), check that the wheel
nuts are tight.
If you have repaired or changed your
tires, check that the wheel nuts are still
tight after driving 1600 km (1000miles).
When using tire chains, be careful not
to damage the aluminum wheels.
Use only the Toyota wheel nuts and
wrench designed for your aluminumwheels.
When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.
As with any wheel, periodically checkyour aluminum wheels for damage. If
damaged, replace immediately.

162This
information has been prepared in ac-
cordance with regulations issued by the
National Highway Traffic Safety Adminis-
tration of the U.S. Department of Trans-
portation. It provides the purchasers and/
or prospective purchasers of Toyota
vehicles with information on uniform tire
quality grading.
Your Toyota dealer will help answer any
questions you may have as you read this information.
DOT quality gradesÐAll passenger
vehicle tires must conform to Federal
Safety Requirements in addition to these grades. These quality grades are
molded on the sidewall.
Treadwear ÐThe treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under con-
trolled conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the governmentcourse as a tire graded 100. The relative
performance of tires depends upon the
actual conditions of their use, however,
and may depart significantly from the norm due to variations in driving habits,
service practices and differences in roadcharacteristics and climate. Traction A, B, C
ÐThe traction grades,
from highest to lowest, are A, B, and C,
and they represent the tire's ability to stop
on wet pavement as measured under
controlled conditions on specified govern-
ment test surfaces of asphalt and con-
crete. A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned to this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction.
Temperature A, B, C ÐThe temperature
grades are A (the highest), B, and C, rep-
resenting the tire's resistance to the gen-
eration of heat and its ability to dissipate heat when tested under controlled condi- tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause the material of the tire to degener- ate and reduce tire life, and excessive
temperature can lead to sudden tire fail-
ure. The grade C corresponds to a level of
performance which all passenger car tires
must meet under the Federal Motor Ve-
hicle Safety Standard No. 109. Grades B
and A represent higher levels of perfor-mance on the laboratory test wheel than
the minimum required by law. Warning: The temperature grade for this
tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed, underinflation, or excessive load- ing, either separately or in combination, can cause heat buildup and possible tirefailure.
