Replace or rotate tires in accordance with maintenance schedules and treadwear.

Checking tires

1. New tread.

2. Treadwear indicator.

3. Worn tread.

The location of treadwear indicators is shown by the “TWI” or “Δ” marks, etc., molded on the sidewall of each tire.

Check spare tire condition and pressure if not rotated.

Tire rotation

- Vehicles with a compact spare tire

Rotate the tires in the order shown.

To equalize tire wear and extend tire life, Lexus recommends that tire rotation is carried out at the same interval as tire inspection.

- Vehicles with a full-size spare tire

Rotate the tires in the order shown.

To equalize tire wear and extend tire life, Lexus recommends that tire rotation is carried out at the same interval as tire inspection.

The tire pressure warning system

Your Lexus is equipped with a tire pressure warning system that uses tire pressure warning valves and transmitters to detect low tire inflation pressure before serious problems arise.

Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and transmitters must also be installed.

When new tire pressure warning valves and transmitters are installed, new tire pressure warning valve and transmitter ID codes must be registered in the tire pressure warning computer and the tire pressure warning system must be initialized. Have tire pressure warning valve and transmitter ID codes registered by your Lexus dealer.

Initializing the tire pressure warning system

The tire pressure warning system must be initialized in the following circumstances:

When tire inflation pressure is changed such as when changing travelling speed or load weight
When changing the tire size.

When the tire pressure warning system is initialized, the current tire inflation pressure is set as the benchmark pressure.

How to initialize the tire pressure warning system

1. Park the vehicle in safe place and turn the “POWER” switch off.

Initialization cannot be performed while the vehicle is moving.

2. Adjust the tire inflation pressure to the specified cold tire inflation pressure level.

Make sure to adjust the tire pressure to the specified cold tire inflation pressure level. The tire pressure warning system will operate based on this pressure level.

3. Turn the “POWER” switch to ON mode.

4. Press and hold the tire pressure warning reset button until the tire pressure warning light flashes slowly 3 times.

Wait for a few minutes with the “POWER” switch on and then turn the “POWER” switch off.

Registering ID codes

The tire pressure warning valve and transmitter is equipped with a unique ID code. When replacing a tire pressure warning valve and transmitter, it is necessary to register the ID code. Have the ID code registered by your Lexus dealer.

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, and 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 warning 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 flashes for 1 minute and stays on to indicate a
system malfunction.

Tire life

Any tire over 6 years old must be checked by a qualified technician even if it has seldom
or never been used or damage is not obvious.

If the tread on snow tires wears down below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is lost.

Maximum load of tire

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

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 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 performance
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 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 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 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.

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 warning 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 button, the tire pressure warning
light does not flash 3 times.

After carrying out the initialization procedure, the tire pressure warning light
flashes for 1 minute then stays on after driving for 20 minutes.

Routine tire inflation pressure checks

The tire pressure warning system does not replace routine tire inflation pressure
checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.

CAUTION:
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
damage to parts of the drive train, 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 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.

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.

NOTICE:
Repairing or replacing tires, wheels and tire pressure warning valves and transmitters
When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitter, contact your Lexus dealer as the tire pressure warning valves and transmitters
may be damaged if not handled correctly.

To avoid damaging the tire pressure warning valves and transmitters Do not use liquid sealants on flat tires.

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 cushioning
ability of the tires. In addition, driving on rough roads may cause damage to the
tires themselves, as well as the vehicle’s wheels and body.

If tire inflation pressure of each tire becomes low while driving Do not continue driving, or your tires and/or wheels may be ruined.
