Maintenance and care
■Ty p e s o f t i r e s
1. Summer tires: 
Summer tires are high-speed capability tires best suited to highway driving
un
der dry conditions. Since summer tires do not have the same traction perfor-
mance as snow tires, summer tires are in adequate f
or driving on snow-covered
or icy roads. 
For driving on snow-covered roads or icy roads, we recommend using snow
t
ires. If installing snow tires, be sure to replace all four tires.
2. All season tires: 
All season tires are designed to provid e better tr
action in snow and to be ade-
quate for driving in most winter conditions , as
well as for use year round. All sea-
son tires, however, do not have adequa te
traction performance compared with
snow tires in heavy or loose snow. Also, a ll season tires fall short in acceleration
and handling performance compared wi th summer tires in highway driving.
3. Snow tires: 
For driving on snow-covered roads or icy roads, we recommend using snow
tir

es. If you need snow tires, select tire s of the same size, construction and load
capacity as the originally installed tires. Since your vehicle has radial tires as
original equipment, make sure your snow tires also have radial construction. Do
not install studded tires without first checking local regulations for possible
restrictions. Snow tires should be installed on all wheels. (P.149 )

CAUTION
■When inspecting or replacing tires
Observe the following instructions, as failure to do so may cause dangerous han-
dling characteristics resulting in loss of contr
ol and could cause death or serious
injury.
• Do not mix radial, bias belted, or bias-ply tir
es on your vehicle, or use tires other
than the manufacturer’s recommended size.
• Do not mix summer and all season tires on your vehicle.
• Do not use tires other than the manufact ur
er’s designated tires, and never mix
tires or wheels of different size to the originals.
NOTICE
■To prevent malfunction of the tire pressure warning system
Do not push the reset switch without adjusting the tire inflation pressure to the spec-
ified level. Otherwise, the low tire pressure warning may not function correctly.
(  P.334 )
■If tire pressure becomes low while driving
Do not continue driving, your ti r
es and/or wheels may be ruined.

4-3. Do-it-yourself maintenance
CAUTION
■When inspecting and adjusting tire pressure
Be sure to reinstall the tire valve caps. 
Without the valve caps, dirt or moisture c
ould get into the valve and cause air leak-
age, which could result in an accident. If the caps ha
ve been lost, have new ones put
on as soon as possible.
■Check tire pressure regularly
The tire pressure warning system will warn you when one or more of your tires are
si
gnificantly under-inflated. However, ther e are combinations which the system will
not detect (both tires on the same side or same axle). Thus it is important to check
the tire pressure of all tires regularly.
■Proper inflation is critical to safe tire performance
Keep your tires properly inflated. Otherwise, the following conditions may occur
and r

esult in an accident causi ng in death or serious injury.
•Excessive wear
• Uneven wear
• Poor handling
• Possibility of blowouts from an overheated tire
• Poor sealing of the tire bead
• Wheel deformation and/or tire separation
• A greater possibility of tire damage from road hazards

Maintenance and care
Wheels
If your wheel is bent, cracked or heavily corroded, the wheel should be
replaced.

Otherwise, the tire may separate from t
he wheel or cause loss of handling
control.
■ Wheel selection
When replacing wheels, care should be tak
en to ensure that they are
equivalent to those removed in lo ad capacity, diameter, rim width,
and offset.
Replacement wheels are available at your Lexus dealer.
Lexus does not recommend using:
• A wheel of a different size or type;
• Used wheels; or
• Bent wheels that have been straightened.
■ Aluminum wheel precautions
●Use only Lexus wheel nuts and a wrench designed for your alumi-
num wheels if you have rotated, repaired or changed your tires.
●Check that the wheel nuts are st ill tight after driving 1000 miles
(1600 km).
●Be careful not to damage the aluminum wheels when using tire
chains.
●Use only Lexus balance weights or equivalent and a plastic or rub-
ber hammer when balancing your wheels.

4-3. Do-it-yourself maintenance
CAUTION
■When replacing wheels
●Do not use wheels other than the manufacturer’s recommended wheel or wheel
size, as this may result in loss of handling control.
●Never using 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.
