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
●Use only Lexus wheel nuts and wren ches designed for use with your
aluminum 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 alum inum wheels when using tire chains.
●Use only Lexus genuine balance wei ghts or equivalent and a plastic or
rubber hammer when balancing your wheels.
If a wheel is bent, cracked or heav ily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause a loss of han-
dling control.

Maintenance and care
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warnin g system to provide advance warning in the
event of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure
warning valves and transmitte rs must be installed. (P. 695)
CAUTION
■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.
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 wh eels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-
genuine wheels.

Gasoline vehicles: If a tow truck is
not available in an emergency, your
vehicle may be temporarily towed
using a cable or chain secured to
the emergency towing eyelet. This
should only be attempted on hard
surfaced roads for short distances
at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The vehi-
cle’s wheels, drive train, axles, steeri ng and brakes must be in good condi-
tion.
Hybrid vehicles: If a tow truck is not available in an emergency, your vehi-
cle may be temporarily towed using a cable or chain secured to the emer-
gency towing eyelet. This should only be attempted on hard surfaced
roads for short distances at under 18 mph (30 km/h).
A driver must be in the vehicle to steer and operate the brakes. The vehi-
cle’s wheels, drive train, axles, steeri ng and brakes must be in good condi-
tion.
