LX570_OM_OM60L96U_(U) Selecting tire chains
Use the correct tire chain size wh en mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(0.20 in. [5 mm] in diameter)
Cross chain
(0.25 in. [6.3 mm] in diameter)
Regulations on the use of tire chains
● Regulations regarding the use of tire chains vary acco rding to location
and type of road. Always check local regulations before installing
chains.
● Retighten the chains after driving 1/4 - 1/2 mile (0.5 - 1.0 km). ■
Tire chains
Observe the following precautions when installing and removing chains. ●
Install and remove tire chains in a safe location. ●
Install tire chains on the rear tires only. Do not install the chai ns on the front tires.●
Install tire chains following the instruct ions provided in the accompanying man-
ual.

When driving
LX570_OM_OM60L96U_(U) CAUTION■
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in a loss of vehicle control and cause death or serious
injury. ●
Use tires of the size sp ecified for your vehicle.●
Maintain the recommended level of tire inflation pressure. ●
Do not drive in excess of 75 mph (120 km/h ), regardless of the type of snow tires
being used. ●
Snow tires should be in stalled on all wheels.■
Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failing to do so may result in the vehicle being unable to be driven safely, and may
cause death or serious injury. ●
Do not drive in excess of the speed limit specified for the tire chains being used or
30 mph (50 km/h), whichever is lower. ●
Avoid driving on bumpy road surfaces or over potholes. ●
Avoid sudden acceleration, abrupt steering, sudden braking and shifting opera-
tions that cause sudden engine braking. ●
Slow down sufficiently before entering a curve to ensure that vehicle control is
maintained.■
When installing tire chains
Turn off the vehicle height control.
The vehicle height may change due to the automatic leveling function and you may
catch part of your body in the vehi cle, resulting in an accident. (  P. 320)

Maximum load of tire
Check that the number given by dividing the maximum load by 1.10 of the replace-
ment tire is greater than 1/2 of the Gr oss Axle Weight Ratings (GAWR) of either
the front axle or the rear axle, whichever is greater.

Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway driving
under dry conditions. Since summer tires do not have the same traction perfor-
mance as snow tires, summer tires are inadequate for driving on snow-covered
or icy roads. For driving on snow-cover ed roads or icy roads, the use of snow
tires is recommended. When inst alling snow tires, be sure to replace all four tires.
2 All season tires
All season tires are designed to provide better traction 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, all season tires fall short in acceleration
and handling performance compared with summer tires in highway driving.
3Snow tires
For driving on snow-covered roads or icy roads, we recommend using snow
tires. If you need snow tires, select ti res of the same size, construction and load
capacity as the originally installed tires. Si nce your vehicle has radial tires as orig-
inal equipment, make sure your snow tire s also have radial construction. Do not
install studded tires without first checking local regulations for possible restric-
tion. Snow tires should be installed on all wheels. (  P. 376)For the GAWR, see the Certification Label.
For the maximum load of the tire, see the load
limit at maximum cold tire inflation pressure
mentioned on the sidewall of the tire.

Maintenance and care
LX570_OM_OM60L96U_(U) Wheels If a wheel is bent, cracked or heavil y corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of handling
control.
■ Wheel selection
When replacing wheels, care shoul d be taken to ensure that they
are equivalent to those removed in load capacity, diameter, rim
width, and inset
* .
Replacement wheels are available at your Lexus dealer.
* : Conventionally referr ed to as “offset”.
Lexus does not recommend using:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions
● Use only Lexus wheel nuts and wrenches designed for use with
your aluminum wheels.
● When rotating, repairing or chan ging your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
● Be careful not to damage the aluminum wheels when using tire
chains.
● Use only Lexus genuine balanc e weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

8345-2. Steps to take in an emergency
LX570_OM_OM60L96U_(U) ■
When a tire is replaced with a spare tire
The spare tire is also equipped with the tire pressure warning valve and transmitter.
The tire pressure warning light will turn on if the tire inflation pressure of the spare
tire is low. If a tire goes flat, even though the flat tire is replaced with the spare tire,
the tire pressure warning li ght does not turn off. Repl ace the spare tire with the
repaired tire and adjust the proper tire in flation pressure. The ti re pressure warning
light will turn off after a few minutes. ■
If the tire pressure warning system is inoperative
The tire pressure warning system will become inoperative in the following condi-
tions: (When the condition becomes norm al, the system will work properly.)●
If tires not equipped with ti re pressure warning valves and transmitters are used.●
If the ID code on the tire pressure warn ing valves and transmitters is not regis-
tered in the tire pressure warning computer. ●
If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm 2
or bar) or higher.
The tire pressure warning system may be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.) ●
If electronic devices or facilities using similar radio wave frequencies are
nearby. ●
If a radio set at similar frequencies is in use in the vehicle. ●
If a window tint that affects the radio wave signals is installed. ●
If there is a lot of snow or ice on the ve hicle, in particular around the wheels or
wheel housings. ●
If non-genuine Lexus wheels are used. (Even if you use Lexus wheels, the tire
pressure warning system may not work properly with some types of tires.)●
If tire chains are used. ●
If the spare tire is in a location subject to poor radio wave signal reception. ●
If a large metallic object which can interfere with signal reception is put in the
luggage compartment.
