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.

• New tread
• Worn tread
• 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:

• The treadwear indicators are showing on a tire.
• 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 Toyota 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 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 Regulation 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

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.
• 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.
• 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.
• 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.
• 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 Toyota.
• 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.

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.

NOTICE

• 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, 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.

When rotating the tires

Make sure that the power switch is OFF. If the tires are rotated while the power switch is in ON, the tire position information will not be updated. If this accidentally occurs, either turn the power switch to OFF and then to ON, or initialize the system after checking that the tire pressure is properly adjusted.

• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device If tire position information is not correctly displayed due to the radio wave conditions, the display may be corrected by driving and changing the radio wave conditions.
• When the vehicle is parked, the time taken for the warning to start or go off could be extended.
• When tire inflation pressure declines rapidly for example when a tire has burst, the warning may not function.

Installing tire pressure warning valves and transmitters

When replacing the tires or wheels, the tire pressure warning valve and transmitters must be installed to the wheels which will be installed to the vehicle. When new tire pressure warning valve 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.

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 blinks for 1 minute and stays on to indicate a system malfunction.

NOTICE

NOTICE

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

Installing the tire

• Remove any dirt or foreign matter from the wheel contact surface.
• Install the tire and loosely tighten each wheel bolts by hand by approximately the same amount.
• Lower the vehicle.
• Firmly tighten each wheel bolt two or three times in the order shown in the illustration.

Tire inflation pressure

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.

Checking the specified tire inflation pressure

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

Inspection and adjustment procedure

• A Tire valve
• B Tire pressure gauge

1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge onto the tire valve.
3. Read the pressure using the gauge gradations.
4. If the tire inflation pressure is not at the recommended level, adjust the pressure. If you add too much air, press the center of the valve to deflate.
5. After completing the tire inflation pressure measurement and adjustment, apply soapy water to the valve and check for leakage.
6. Put the tire valve cap back on.

Tire inflation pressure check interval

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

Effects of incorrect tire inflation pressure

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

• Reduced electricity consumption
• Reduced driving comfort and poor handling
• Reduced tire life due to wear
• Reduced safety
• Damage to the drive train If a tire needs frequent inflating, 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 or 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. It is difficult to judge if a tire is properly inflated based only on its appearance.
• It is normal for the tire inflation pressure to be higher after driving as heat is generated in the tire. Do not reduce tire inflation pressure after driving.
• Never exceed the vehicle capacity weight. Passengers and luggage weight should be placed so that the vehicle is balanced

WARNING

Proper inflation is critical to save tire performance

Keep your tires properly inflated. If the tires are not properly inflated, the following conditions may occur which could lead to an accident resulting in death or serious injury

• Excessive wear
• Uneven wear
• Poor handling
• Possibility of blowouts resulting from overheated tires
• Air leaking from between tire and wheel
• Wheel deformation and/or tire damage
• Greater possibility of tire damage while driving (due to road hazards, expansion joints, sharp edges in the road, etc.)

NOTICE

When inspecting and adjusting tire inflation pressure Be sure to put the tire valve caps back on. If a valve cap is not installed, dirt or moisture may get into the valve and cause an air leak, resulting in decreased tire inflation pressure

Wheels

If a wheel is bent, cracked or heavily corroded, it should be replaced. Otherwise, the tire may separate from the wheel or cause a loss of handling control.

Wheel selection

When replacing wheels, care should be taken to ensure that they are equivalent to those removed in load capacity, diameter, rim width and inset*. Replacement wheels are available at your Toyota dealer. *: Conventionally referred to as offset. Toyota does not recommend using the following:

•  Wheels of different sizes or types
•  Used wheels
•  Bent wheels that have been straightened

When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advance warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, tire pressure warning valves and transmitters must be installed

WARNING

 When replacing wheels

• Do not use wheels that are a different size from those recommended in the Owner’s Manual, as this may result in a loss of handling control.
• Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing so may result in an accident, causing death or serious injury.

Wheel bolts

• Observe the following precautions to reduce the risk of death or serious injury:
• Do not over tighten.
• Never use oil or grease on the wheel bolts. Oil and grease may cause the wheel bolts to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel bolts to loosen and the wheel may fall off, causing a serious accident. Remove any oil or grease from the wheel bolts.
• If there are any cracks or deformations in the wheel bolts, or if the surface treatment becomes worn, have the wheel bolts replaced at your Toyota dealer. Failure to follow these precautions could cause the wheel bolts to loosen and the tire to fall off, resulting in death or serious injury.
• Use of defective wheels is prohibited Do not use cracked or deformed wheels. Doing so could cause the tire to leak air during driving, possibly causing an accident.

NOTICE

• Replacing tire pressure warning valves and transmitters
• Because tire repair or replacement may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by your Toyota dealer or another qualified service shop. In addition, make sure to purchase your tire pressure warning valves and transmitters at your Toyota dealer
