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 designed 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 weights 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 pressure. Whenever wheels are replaced, the tire
pressure warning valves and transmitters must be installed. (P. 271)

An exclusive hub socket for the wheel bolts of
