6-3. Do-it-yourself maintenance

Tires

is shown by a “TWI” or “ ” mark,

etc., molded into the sidewall of

each tire.

Replace or rotate tires in

accordance with mainte-

nance schedules and tread-

wear.

Replace the tires if the treadwear

indicators are showing on a tire.

■When to replace your vehicle’s

tires

Checking tires

Tires should be replaced if:

●The treadwear indicators are

showing on a tire.

Check if the treadwear indica-

tors are showing on the tires.

Also check the tires for uneven

wear, such as excessive wear

on one side of the tread.

●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 can-

not be properly repaired due to the

size or location of a cut or other

damage

Check the spare tire condition

and pressure if not rotated.

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.

6

■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. (P.626)

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.

(P.448)

■If the tread on snow tires wears

down below 0.16 in. (4 mm)

■Tire types

The effectiveness of the tires as

snow tires is lost.

●Summer tires

Summer tires are high-speed perfor-

mance 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 install-

ing snow tires, be sure to replace all

four tires.

WARNING

■When inspecting or replacing

tires

Observe the following precautions

to prevent accidents.

Failure to do so may cause dam-

age to parts of the drive train as

well as dangerous handling char-

acteristics, which may lead to an

accident resulting in death or seri-

ous injury.

●Do not mix tires of different

makes, models or tread pat-

terns.

●All season tires

All season tires are designed to pro-

vide better traction in snow and to

be adequate for driving in most win-

ter conditions as well as for use

year-round. All season tires, how-

ever, do not have adequate traction

performance compared with snow

tires in heavy or loose snow. Also,

all season tires fall short in accelera-

tion and handling performance com-

pared with summer tires in highway

driving.

Also, do not mix tires of remark-

ably different treadwear.

●Do not use tire sizes other than

those recommended by Toyota.

●Do not mix differently con-

structed 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 previ-

ously.

●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, con-

struction and load capacity as the

originally installed tires. Since your

vehicle has radial tires as original

equipment, make sure your snow

●Do not use tires with different

load rating and/ or speed sym-

bol than what is specified on tire

pressure label or in owner’s

manual.

 Vehicles with a spare tire of

the same wheel type as the

installed tires

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.

Tire rotation

Tire pressure warning

system

To equalize tire wear and extend

tire life, Toyota recommends that

tire rotation is carried out at the

same interval as tire inspection.

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.

Do not fail to initialize the tire pres-

sure warning system after tire rota-

tion.

not operate properly

■Warning performance of the tire

pressure warning system

●In the following cases, the tire

pressure warning system may not

operate properly.

• If non-genuine Toyota wheels are

used.

• A tire has been replaced with a

tire that is not an OE (Original

Equipment) tire.

• A tire has been replaced with a

tire that is not of the specified size.

• Tire chains, etc., are equipped.

• An auxiliary-supported run-flat tire

is equipped.

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 rotating the tires

It is necessary to register the

position of each wheel after per-

forming a tire rotation.

■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.

Wheel position registration can

be performed by oneself. Wheel

position registration is per-

formed by driving forward with

moderate left and right turns.

However, depending on the driv-

inflation pressure

Tire pressure gauge

1 Remove the tire valve cap.

When checking tire inflation pres-

sure, observe the following:

2 Press the tip of the tire pres-

sure gauge onto the tire

valve.

●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.

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.

●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.

5 After completing the tire infla-

tion pressure measurement

and adjustment, apply soapy

water to the valve and check

for leakage.

●Never exceed the vehicle capacity

weight.

Passengers and luggage weight

should be placed so that the vehi-

cle is balanced.

once a month. Do not forget to

check the spare.

■Effects of incorrect tire inflation

pressure

●Excessive wear

●Uneven wear

●Poor handling

Driving with incorrect tire inflation

pressure may result in the following:

●Reduced fuel economy

●Reduced driving comfort and poor

handling

●Possibility of blowouts resulting

from overheated tires

●Reduced tire life due to wear

●Reduced safety

●Air leaking from between tire

■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 pres-

WARNING

NOTICE

■When replacing wheels

■Replacing tire pressure warn-

ing valves and transmitters

●Do not use wheels that are a dif-

ferent size from those recom-

mended in the Owner’s Manual

or certification label, as this may

result in a loss of handling con-

trol.

●Because tire repair or replace-

ment may affect the tire pres-

sure warning valves and

transmitters, make sure to have

tires serviced by your Toyota

dealer or other qualified service

shop. In addition, make sure to

purchase your tire pressure

warning valves and transmit-

ters at your Toyota dealer.

●Never use an inner tube in a

leaking wheel which is designed

for a tubeless tire.

Doing so may result in an acci-

dent, causing death or serious

injury.

●Ensure that only genuine Toyota

wheels are used on your vehi-

cle.

Tire pressure warning valves

and transmitters may not work

properly with non-genuine

wheels.

■When installing the wheel

nuts

Never use oil or grease on the

wheel bolts or wheel nuts. Oil and

grease may cause the wheel nuts

to be excessively tightened, lead-

ing to bolt or disc wheel damage.

In addition, the oil or grease can

cause the wheel nuts to loosen

and the wheel may fall off, caus-

ing an accident and resulting in

death or serious injury. Remove

any oil or grease from the wheel

bolts or wheel nuts.

Aluminum wheel precau-

tions

 Use only Toyota wheel nuts

and wheel nut wrenches

designed for use with your

aluminum wheels.

■Use of defective wheels pro-

hibited

 When rotating, repairing or

changing your tires, check

that the wheel nuts are still

tight after driving 1000 miles

(1600 km).

Do not use cracked or deformed

wheels. Doing so could cause the

tire to leak air during driving, pos-

sibly causing an accident.

 Be careful not to damage the

aluminum wheels when using

tire chains.

 Use only Toyota genuine bal-

ance weights or equivalent

and a plastic or rubber ham-

mer when balancing your

wheels.
