NOTICE
■Do not drive the vehicle with a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the wheel
beyond repair.

●Ensure that there is no object caught between the tire and the vehicle underbody.
●Vehicles with kinetic dynamic suspension: To avoid damaging the suspension sys-
tem, make sure that the spare tire does not interfere with the suspension compo-
nents when stowed.
■When replacing the tires
●When removing or fitting the wheels, tires or the tire pressure warning valve and
transmitter, contact your Lexus dealer as the tire pressure warning valve and
transmitter may be damaged if not handled correctly.
●Replace the grommets for the tire pressure warning valves and transmitters as
well.

Tire inflation pressure
(Recommended cold tire inflation
pressure)
Driving under normal conditions 32 psi (220 kPa, 2.2
kgf/cm2 or bar)
Driving at high speeds above 100 mph (160
km/h) (in countries where such speeds are per-
mitted by law) Add 9 psi (60 kPa, 0.6 kgf/cm
2 or bar) to the
front tires and rear tires. Never exceed the
maximum cold tire inflation pressure indicated
on the tire sidewall.

bias-ply tire.
TUBELESS or TUBE TYPE
A tubeless tire does not have a tube an d air is directly filled in the tire. A
tube type tire has a tube inside the ti re and the tube maintains the air pres-
sure.
Load limit at maximum cold tire inflation pressure ( P. 395)
Maximum cold tire inflation pressure ( P. 395)
