Tires

For reasons of proper performance, safety, and better fuel econ-

omy, always maintain recommended tire inflation pressures and

stay within the recommended load limits and weight distribu-

tion.

WARNING

■Using Different Tire Types

Driving your vehicle with different types of tires is dangerous. It could

cause poor handling and poor braking; leading to loss of control.

Except for the limited use of the temporary spare tire, use only the same

type tires (radial, bias-belted, bias-type) on all four wheels.

■Using Wrong-Sized Tires

Using any other tire size than what is specified for the vehicle (P. 553)

is dangerous. It could seriously affect ride, handling, ground clearance,

tire clearance, and speedometer calibration. This could cause you to

have an accident. Use only tires that are the correct size specified for

the vehicle.

Tire Inflation Pressure

Inspect all tire pressures monthly (including the spare) when the tires

are cold. Maintain recommended pressures for the best ride, han-

dling, and minimum tire wear.

Refer to the specification charts (P. 553).

With tire pressure monitoring system:

After adjusting the tire pressure, initialization of the tire pressure mon-

itoring system is necessary to make the system operate normally.

Refer to Tire Pressure Monitoring System Initialization on P. 244.

5-3. Owner Maintenance

●Always check tire pressure when tires are cold.

●Warm tires normally exceed recommended pressures. Do not release

air from warm tires to adjust the pressure.

●Underinflation can cause reduced fuel economy, uneven and acceler-

ated tire wear, and poor sealing of the tire bead, which will deform the

wheel and cause separation of tire from rim.

●Overinflation can produce a harsh ride, uneven and accelerated tire

wear, and a greater possibility of damage from road hazards.

Keep your tire pressure at the correct levels. If one frequently needs

inflating, have it inspected.

WARNING

■Always inflate the tires to the correct pressure

Overinflation or underinflation of tires is dangerous. Adverse handling or

unexpected tire failure could result in a serious accident.

Refer to Tires on (P. 553).

■Use only a Toyota-genuine tire valve cap

Use of a non-genuine part is dangerous as the correct tire air pressure

cannot be maintained if the tire valve becomes damaged. If the vehicle

is driven under this condition, the tire air pressure will decrease which

could result in a serious accident. Do not use any part for the tire valve

cap that is not a Toyota-genuine part.

Tire Rotation

During rotation, inspect them for

correct balance.

spare tire in rotation.

5-3. Owner Maintenance

Also, inspect them for uneven wear and damage. Abnormal wear is

usually caused by one or a combination of the following:

• Incorrect tire pressure

• Improper wheel alignment

• Out-of-balance wheel

• Severe braking

After rotation, inflate all tire pressures to specification (P. 553) and

inspect the lug nuts for tightness.

With tire pressure monitoring system:

After adjusting the tire pressure, initialization of the tire pressure mon-

itoring system is necessary to make the system operate normally.

Refer to Tire Pressure Monitoring System Initialization on P. 244.

WARNING

■Rotate tires periodically

Irregular tire wear is dangerous. To equalize tire wear and extend tire

life, Toyota recommends that tire rotation is carried out at the same

interval as tire inspection.

5

For scheduled maintenance information, please refer to the “Owner’s

Manual Supplement/Scheduled Maintenance Guide”.

NOTICE

Rotate unidirectional tires and radial tires that have an asymmetrical

tread pattern or studs only from front to rear, not from side to side. Tire

performance will be reduced if rotated from side to side.

Replacing a Tire

5-3. Owner Maintenance

If a tire wears evenly, a wear indicator will appear as a solid band

across the tread.

Replace the tire when this happens.

Worn tread

Tread wear indicator

You should replace the tire before the band crosses the entire tread.

With tire pressure monitoring system:

After adjusting the tire pressure, initialization of the tire pressure mon-

itoring system is necessary to make the system operate normally.

Refer to Tire Pressure Monitoring System Initialization on P. 244.

Tires degrade over time, even when they are not being used on the road.

It is recommended that tires generally be replaced when they are 6 years

or older. Heat caused by hot climates or frequent high loading conditions

can accelerate the aging process. You should replace the spare tire when

you replace the other road tires due to the aging of the spare tire. The

period in which the tire was manufactured (both week and year) is indi-

cated by a 4-digit number.

Refer to Tire Labeling on P. 522.

WARNING

■Always use tires that are in good condition

Driving with worn tires is dangerous. Reduced braking, steering, and

traction could result in an accident.

■Replace all four tires at the same time

Replacing just one tire is dangerous. It could cause poor handling and

poor braking resulting in loss of vehicle control. Toyota strongly recom-

mends that you replace all four tires at the same time. If you replace

only two tires, the new tires should be installed on the rear of the vehi-

cle.

Temporary Spare Tire

Inspect the temporary spare tire at least monthly to make sure it is

properly inflated and stored.

The temporary spare tire is easier to handle because of its construc-

tion which is lighter and smaller than a conventional tire. This tire

should be used only for an emergency and only for a short distance.

Use the temporary spare tire only until the conventional tire is

repaired, which should be as soon as possible.

Refer to Tires on P. 553.

●The temporary spare tire condition gradually deteriorates even if it has

not been used.

●Tires degrade over time, even when they are not being used on the

road. It is recommended that tires generally be replaced when they are

6 years or older. Heat caused by hot climates or frequent high loading

conditions can accelerate the aging process. You should replace the

spare tire when you replace the other road tires due to the aging of the

spare tire. The period in which the tire was manufactured (both week

and year) is indicated by a 4-digit number.

5

Refer to Tire Labeling on P. 522.

NOTICE

●Do not use your temporary spare tire rim with a snow tire or a conven-

tional tire. Neither will properly fit and could damage both tire and rim.

●The temporary spare tire has a tread life of less than 3,000 miles

(5,000 km). The tread life may be shorter depending on driving condi-

tions.

●The temporary spare tire is for limited use, however, if the tread wear

solid-band indicator appears, replace the tire with the same type of

temporary spare (P. 417).

Replacing a Wheel

Proper tire balancing provides the best riding comfort and helps

reduce tread wear. Out-of-balance tires can cause vibration and

uneven wear, such as cupping and flat spots.

When replacing a wheel, make sure the new one is the same as the orig-

inal factory wheel in diameter, rim width, and offset (inset/outset).

For details, contact your Toyota dealer.

WARNING

■Always use wheels of the correct size on your vehicle

Using a wrong-sized wheel is dangerous. Braking and handling could

be affected, leading to loss of control and an accident.

NOTICE

A wrong-sized wheel may adversely affect:

●Tire fit

●Wheel and bearing life

●Ground clearance

●Snow-chain clearance

●Speedometer calibration

●Headlight aim
