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 any authorized Toyota dealer or repairer, or

another duly qualified and equipped professional.

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 4 mm (0.16 in.)

The effectiveness of the tires as snow tires is lost.

CAUTION

4

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 dan-

gerous 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.

273

4-3. Do-it-yourself maintenance

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.

274

4-3. Do-it-yourself maintenance

Tire inflation pressure

Make sure to maintain 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. (P. 355)

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 inflating, have it checked by any authorized Toyota

dealer or repairer, or another duly qualified and equipped professional.

Instructions for checking tire inflation pressure

4

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 1.5 km or 1 mile, 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

pressure that is even just a few pounds off can affect ride quality and

handling.

 Do not reduce tire inflation pressure after driving. It is normal for tire infla-

tion 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.

275

4-3. Do-it-yourself maintenance

CAUTION

Proper inflation is critical to save tire performance

Keep your tires properly inflated. Otherwise, the following conditions may

occur and result in an accident causing death or serious injury:

 Excessive wear

 Uneven wear

 Poor handling

 Possibility of blowouts resulting from overheated tires

 Poor sealing of the tire bead

 Wheel deformation and/or tire separation

 A greater possibility of tire damage from road hazards

NOTICE

When inspecting and adjusting tire inflation pressure

Be sure to put the tire valve caps back on.

Without the valve caps, dirt or moisture could get into the valve and cause

air leakage, which could result in an accident. If the caps are lost, replace

them as soon as possible.

276

4-3. Do-it-yourself maintenance

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 any authorized Toyota

dealer or repairer, or another duly qualified and equipped profes-

sional.

*: Conventionally referred to as “offset”.

Toyota does not recommend using the following:

 Wheels of different sizes or types

 Used wheels

4

 Bent wheels that have been straightened

 Aluminum wheel precautions (if equipped)

 Use only Toyota wheel bolts and wrenches designed for use

with your aluminum wheels.

 When rotating, repairing or changing your tires, check that the

wheel bolts are still tight after driving 1600 km (1000 miles).

 Be careful not to damage the aluminum wheels when using

tire chains.

 Use only Toyota genuine balance weights or equivalent and

use a plastic or rubber hammer when balancing your wheels.

277

4-3. Do-it-yourself maintenance

CAUTION

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 tube-

less tire. Doing so may result in an accident, causing death or serious

injury.
