Wheels
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:
●
Wheels of different sizes or types
●
Used wheels
●
Bent wheels that have been straightened
●
Steel wheels (2WD F SPORT models only)
●
Use only Lexus wheel nuts and wrenches designed for use with your alumi-
num wheels.
●
When rotating, repairing or changing your tires, check that the wheel nuts are
still tight after driving 1000 miles (1600 km).
●
Be careful not to damage the aluminum wheels when using tire chains.
●
Use only Lexus genuine balance weights or equivalent and a plastic or rubber
hammer when balancing your wheels.
■
When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and transmit-
ters that allow the tire pressure warning system to provide advance warning in the event
of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning
valves and transmitters must be installed. (
If a wheel is bent, cracked or heavily corroded, it should be replaced. Other-
wise, the tire may separate from the wheel or cause a loss of handling control.

WARNING
■
When replacing wheels
●
Do not use wheels that are a different size from those recommended in the Owner’s
Manual, as this may result in a loss of handling control.
●
Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing
so may result in an accident, causing death or serious injury.
●
2WD F SPORT models: Do not install steel wheels.
The wheel contact surface could be damaged, and the wheel could come off while
driving, which could lead to an accident resulting in death or serious injury.
■
Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an accident.
NOTICE
■
Replacing tire pressure warning valves and transmitters
●
Because tire repair or replacement may affect the tire pressure warning valves and
transmitters, make sure to have tires serviced by your Lexus dealer or other qualified
service shop. In addition, make sure to purchase your tire pressure warning valves
and transmitters at your Lexus dealer.
●
Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-genu-
ine wheels.
