Tire types

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 adequate 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.

3 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 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 local regulations for possible restriction.

Snow tires should be installed on all wheels. (

Initializing the tire pressure warning system

Initialize the tire pressure warning system with the tire inflation pressure adjusted to

the specified level.

■

If you push the tire pressure reset switch accidentally

If initialization is performed, adjust the tire inflation pressure to the specified level

and initialize the tire pressure warning system again.

■

When the initialization of the tire pressure warning system has failed

Initialization can be completed in a few minutes. However, in the following cases,

the settings have not been recorded and the system will not operate properly. If

repeated attempts to record tire inflation pressure settings are unsuccessful, have

the vehicle inspected by your Lexus dealer.

●

When operating the tire pressure warning reset switch, the tire pressure warning

light does not flash 3 times.

●

After carrying out the initialization procedure, the tire pressure warning light

blinks for 1 minute then stays on after driving for about 20 minutes.
