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 specified 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 installed 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 steeri ng, 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.■

Maintenance and care
LX570_OM_OM60L21U_(U) ■
When to replace your vehicle’s tires
Tires should be replaced if: ●
You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric or bulges indicating internal damage ●
A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with your Lexus dealer. ■
Replacing tires and wheels
If the ID code of the tire pressure warn ing valve and transmitter is not registered,
the tire pressure warning system will not work properly. After driving for about 20
minutes, the tire pressure warning light comes on after blinking for 1 minute to indi-
cate a system malfunction. ■
Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been used or damage is not obvious. ■
If the tread wears down 0.16 in. (4 mm) or more on snow tires
The effectiveness of snow tires is lost.

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-covered roads or icy roads, the use of snow tires
is recommended. When installing 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 loos e 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 ic y roads, we recommend using snow tires.
If you need snow tires, select tires of the same size, construction and load capac-
ity 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 loca l regulations for possible restriction.
Snow tires should be installed on all wheels. (  P. 3 74 )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.

Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a tire
bursts or if sudden air leakage occurs. ■
When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause da mage to parts of the drive tr ain, as well as dangerous
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 th an 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. ■
When initializing the tire pressure warning system
Do not push the tire pressure warning reset switch without first adjusting the tire
inflation pressure to the specified level. Otherwise, the tire pressure warning light
may not come on even if the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.
