REPLACING WHEELS
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, a tire may slip off
a wheel or they may cause loss of handling control.
Replacement with used wheels is not recommended as
they may have been subjected to rough treatment or
high mileage and could fail without warning. Also, bent
wheels which have been straightened may have hidden
structural damage and therefore should not be used.
Never use an inner tube in a leaking wheel which is
designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to
ensure that they are equivalent to those removed in
load capacity, diameter, rim width, and offset.
Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing 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.
ALUMINUM WHEEL PRECAUTIONS
After driving your vehicle the first 1600 km (1000
miles), check that the wheel nuts are tight.
If you have rotated, repaired, or changed your tires,
check that the wheel nuts are still tight after driving
1600 km (1000 miles).
When using tire chains, be careful not to damage the
aluminum wheels.
Use only the Lexus wheel nuts and wrench designed
for your aluminum wheels.
When balancing your wheels, use only Lexus
balance weights or equivalent and a plastic or rubber
hammer.
As with any wheel, periodically check your aluminum
wheels for damage. If damaged, replace
immediately.
