Maintenance and care
Wheels
n When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and
transmitters that allow the tire pressure warning system to provide advanced warn-
ing in the event of a loss in tire inflation pressure. Whenever wheels are replaced,
tire pressure warning valves and transmitters must be installed. (→P. 479)
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause a loss of han-
dling control.
n 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 inset*.
Replacement wheels are available at your Lexus dealer.
*: Conventionally referred to as “offset”.
Lexus does not recommend using the following:
l Wheels of different sizes or types
l Used wheels
l Bent wheels that have been straightened
n Aluminum wheel precautions
l Use only Lexus wheel nuts and wrenches designed for use with
your aluminum wheels.
l When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
l Be careful not to damage the aluminum wheels when using tire
chains.
l Use only Lexus genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.
