8-5. Tire maintenance
Wheels
If a wheel is bent, cracked or heavily
corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel, causing a loss of
handling control.
Wheel selection
When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset
Replacement wheels are available at
your Lexus dealer.

Lexus does not recommend using the
following:
Wheels of different sizes or types
Used wheels
Bent wheels that have been straight-
ened
When replacing wheels
■
The wheels of your vehicle are equipped
with tire pressure warning valves and trans-
mitters 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 pres-
sure warning valves and transmitters must
be installed. (P.448)
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 acci-
dent, causing death or serious injury.
Use the correct wheel bolts for the
●
wheels to be installed.
For details, contact your Lexus dealer.
■
Wheel bolts
*
.
Observe the following precautions to
reduce the risk of death or serious injury:
Do not over tighten.
●
Never use oil or grease on the wheel
●
bolts. Oil and grease may cause the
wheel bolts to be excessively tight-
ened, leading to bolt or disc wheel
damage. In addition, the oil or grease
can cause the wheel bolts to loosen
and the wheel may fall off, causing a
serious accident. Remove any oil or
grease from the wheel bolts.
●
If there are any cracks or deformations
in the wheel bolts, or if the surface
treatment becomes worn, have the
wheel bolts replaced at your Lexus
dealer. Failure to follow these precau-
tions could cause the wheel bolts to
loosen and the tire to fall off, 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 acci-
dent.
