Maintenance and care
Wheels
If your wheel is bent, cracked or heavily corroded, the wheel should be
replaced.

Otherwise, the tire may separate from t
he wheel or cause loss of handling
control.
■ Wheel selection
When replacing wheels, care should be tak
en to ensure that they are
equivalent to those removed in lo ad capacity, diameter, rim width,
and offset.
Replacement wheels are available at your Lexus dealer.
Lexus does not recommend using:
• A wheel of a different size or type;
• Used wheels; or
• Bent wheels that have been straightened.
■ Aluminum wheel precautions
●Use only Lexus wheel nuts and a wrench designed for your alumi-
num wheels if you have rotated, repaired or changed your tires.
●Check that the wheel nuts are st ill tight after driving 1000 miles
(1600 km).
●Be careful not to damage the aluminum wheels when using tire
chains.
●Use only Lexus balance weights or equivalent and a plastic or rub-
ber hammer when balancing your wheels.
