6-3. Do-it-yourself maintenance
roads, the use of snow tires is recom-
mended. When installing snow tires, be
sure to replace all four tires.
● All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions as well
as for use year-round. All season tires,
however, do not have adequate traction
performance compared with snow tires in
heavy or loose snow. Also, all season tires
fall short in acceleration and handling per-
formance compared with summer tires in
highway driving.
● Snow tires
For driving on snow-covered roads or icy
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.

Low profile tires
Generally, low profile tires will wear more
rapidly and tire grip performance will be
reduced on snowy and/or icy roads when
compared to standard tires. Be sure to use
snow tires or tire chains* on snowy and/or
icy roads and drive carefully at a speed
appropriate for road and weather condi-
tions.
*
: Vehicles with front and rear tires of dif-
fering sizes: Tire chains cannot be
mounted. Snow tires should be used
instead.
■ 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.
■ Low profile tires
Low profile tires may cause greater dam-
age than usual to the tire wheel when
sustaining impact from the road surface.
Therefore, pay attention to the following:
