Maintenance and care
Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.
The wheel bolts used are exclusive to the LFA. When replacing the wheels or
wheel bolts, consult your Lexus dealer.
■ Aluminum wheel precautions
●Use only Lexus wheel bolts design ed for use with your aluminum
wheels.
● When repairing or changing your tires, check that the wheel bolts
are still tight after driving 1000 miles (1600 km).
● Use only Lexus genuine balance we ights or equivalent when bal-
ancing your wheels.
■When replacing wheels
The wheels of your Lexus are equipped with tire pressure warning valves and trans-
mitters that allow the tire pressure warning system to provide advanced warning in
the event of a loss in tire inflation pres sure. Whenever wheels are replaced, the tire
pressure warning valves and tran smitters must be installed. (P. 2 7 1 )
■Wheel bolt torque
An exclusive hub socket for the wheel bolts of
the LFA is contained in the tool bag. A 1 /2-
inch (12.7 mm) drive extension bar and a
torque wrench are required to tighten the
bolts.

4-3. Do-it-yourself maintenance
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 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.
■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 tightened, 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 treat-
ment becomes worn, have the wheel bolts replaced at your Lexus dealer.
Failure to follow these precautions could cause the wheel bolts to loosen and the
tire to fall off, resulting in death or serious injury.
●If the wheels are frequently removed and installed due to circuit driving etc.,
Lexus recommends periodic changing of the wheel bolts.
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-
genuine wheels.
