Lexus NX: Tires

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

Checking tires

Check if the treadwear indicators are showing on the tires. Also check the tires for uneven wear, such as excessive wear on one side of the tread.

Check the spare tire condition and pressure if not rotated.

  1. New tread
  2. Worn tread
  3. Treadwear indicator

The location of treadwear indicators is shown by a "TWI" or mark, etc., molded into the sidewall of each tire.

Replace the tires if the treadwear indicators are showing on a tire.

■When to replace your vehicle's tires

Tires should be replaced if:

If you are not sure, consult with your Lexus dealer.

■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.

■Maximum load of tire Check that the maximum load 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

■If the tread on snow tires wears down below 0.16 in. (4 mm) The effectiveness of the tires as snow tires is lost.

WARNING

■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.

NOTICE

■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.

Tire rotation

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.

Do not fail to initialize the tire pressure warning system after tire rotation.

Tire pressure warning system

Your vehicle 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.

■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.

■Situations in which the tire pressure warning system may not operate properly

WARNING

■Caution regarding interference with electronic devices

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 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.

■When replacing the 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 blinks for 1 minute and stays on to indicate a system malfunction.

NOTICE

■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps

■To avoid damage to the tire pressure warning valves and transmitters When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Lexus dealer or other qualified service shop as soon as possible. After use of liquid sealant, make sure to replace the tire pressure warning valve and transmitter when repairing or replacing the tire.

Initializing the tire pressure warning system

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

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 a 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 or of the meter control switches and select .

5. Press or of the meter control switches, select the "Vehicle Settings" and then press .

6. Press or of the meter control switches, select the "TPMS" and then press and hold the .

The "Tire Pressure Recalibrating. Please Wait Until Complete" will be displayed on the multi-information display and the tire pressure warning light will blink slowly 3 times.

When the message disappears, initialization is complete.

■Initializing the tire pressure warning system Initialize the system with the tire inflation pressure adjusted to the specified level

■The initialization operation

■Warning performance of the tire pressure warning system The warning of the tire pressure warning system will change in accordance with the conditions under which it was initialized. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized.

■When 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.

WARNING

■When initializing the tire pressure warning system Do not initializing tire inflation pressure 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.

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.
