roads, we recommend using snow tires. If
you need snow tires, select tires of the
same size, construction and load capacity
as the originally installed tires. Since your
vehicle has radial tires as original equip-
ment, make sure your snow tires also have
radial construction. Do not install studded
tires without first checking local regula-
tions for possible restrictions. Snow tires
should be installed on all wheels.
(P.283)
If the tread on snow tires wears down
■
below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is
lost.
WARNING
When inspecting or replacing tires
■
Observe the following precautions to
prevent accidents.
Failure to do so may cause damage to
parts of the drive train as well as danger-
ous handling characteristics, which may
lead to an accident resulting in death or
serious injury.
Do not mix tires of different makes,
●
models or tread patterns.
Also, do not mix tires of remarkably
different treadwear.
Do not use tire sizes other than those
●
recommended by Lexus.
● Do not mix differently constructed
tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and
snow tires.
● Do not use tires that have been used
on another vehicle.
Do not use tires if you do not know
how they were used previously.
Do not tow if your vehicle has a com-
●
pact spare tire installed.

NOTICE
Driving on rough roads
■
Take particular care when driving on
roads with loose surfaces or potholes.
These conditions may cause losses in tire
inflation pressure, reducing the cushion-
ing ability of the tires. In addition, driving
on rough roads may cause damage to
the tires themselves, as well as the vehi-
cle's wheels and body.
If tire inflation pressure of each tire
■
becomes low while driving
Do not continue driving, or your tires
and/or wheels may be ruined.
Tire rotation
Rotate the tires in the order shown.
To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.
Do not fail to initialize the tire pressure
warning system after tire rotation.
Tire pressure warning system
Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.
