2015 Toyota Land Cruiser Owners Manual - Tires

Tires

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 inflation pressure if not rotated.

• Tire rotation

   

Rotate the tires in the order shown.

To equalize tire wear and extend tire life, Toyota 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.

• The tire pressure warning system

   

Your Toyota 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 tire pressure warning system must be initialized. Have tire pressure warning valve and transmitter ID codes registered by your Toyota dealer.

Initializing the tire pressure warning system

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

   

•  When rotating the tires on vehicles differing with front and rear tire inflation pressures.
•  When changing the tire inflation pressure by changing traveling speed or load weight, etc.
•  When changing the tire size.

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

• How to initialize the tire pressure warning system

   

STEP 1

Park the vehicle in safe place and turn the “ENGINE START STOP” switch to OFF.

While the vehicle is moving, initialization is not performed.

STEP 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.

STEP 3

Turn the “ENGINE START STOP” switch to IGNITION ON mode.

Press and hold the tire pressure warning reset switch until the tire pressure warning light blinks slowly 3 times and the message “TIRE PRESSURE RESET PROCEEDING” appears on the multi-information display.

STEP 5

Wait for a few minutes with the IGNITION ON mode, and then turn the “ENGINE START STOP” switch to 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 of tire pressure warning valve and transmitter. Have the ID code registered by your Toyota 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 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 Toyota 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 comes on after blinking for 1 minute to indicate 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 below 0.16 in. (4 mm) 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 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 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 press the tire pressure reset switch accidental

  ly

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 Toyota dealer.

• When operating the tire pressure warning reset switch, the tire pressure warning light does not blink 3 times and the setting message does not appear on the multi-information display.
• After carrying out the initialization procedure, the tire pressure warning light blinks for 1 minute then stays on after driving for about 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.

• Tire pressure warning system certification

Tire inflation pressure

• Tire inflation pressure

   

The recommended cold tire inflation pressure and tire size is displayed on the tire and loading information label.

• Inspection and adjustment procedure

   

1. Tire valve
2. Tire pressure gauge

STEP 1

Remove the tire valve cap.

STEP 2

Press the tip of the tire pressure gauge onto the tire valve.

STEP 3

Read the pressure using the graduations of the gauge.

STEP 4

If the tire inflation pressure is not within the recommended levels, adjust tire pressure.

If you add too much air, press the center of the valve to lower.

STEP 5

After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage.

STEP 6

Reinstall the tire valve cap.

Make sure to maintain the proper tire inflation pressure. Tire inflation pressure should be checked at least once per month. However, Toyota recommends that tire inflation pressure be checked once every two weeks.

• Tire inflation pressure check interval

   

You should check tire inflation pressure every 2 weeks, or at least once a month.

Do not forget to check the spare.

• Effects of incorrect tire inflation pressure

   

Driving with incorrect tire inflation pressure may result in the following:

• Reduced fuel efficiency
• Reduced driving comfort and tire life
• Reduced safety
• Damage to the drive train

If a tire needs frequent refilling, have it checked by your Toyota dealer.

• Instructions for checking tire inflation pressure

   

When checking tire inflation pressure, observe the following:

• Check only when the tires are cold.

  If your vehicle has been parked for at least 3 hours and has not been driven for more than 1 mile or 1.5 km, you will get an accurate cold tire inflation pressure reading.

• Always use a tire pressure gauge.

  The appearance of the tire can be misleading. In addition, tire inflation pressures that are even just a few pounds off can degrade ride and handling.

• Do not bleed or reduce tire inflation pressure after driving. It is normal for the tire inflation pressure to be higher after driving.
• Never exceed the vehicle capacity weight.

  Passengers and luggage weight should be placed so that the vehicle is balanced.
