Tires

7-3. Do-it-yourself maintenance

Replace the tires if the treadwear

indicators are showing on a tire.

Replace or rotate tires in

accordance with mainte-

nance schedules and tread-

wear.

■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.

Checking tires

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.

●A tire goes flat repeatedly or can-

not 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. (P.556)

New tread

The location of treadwear indicators

is shown by a “TWI” or “ ” mark,

etc., molded into the sidewall of

each tire.

■Tire types

●Summer tires

Owners Manual_USA_M42C01_en

473

7-3. Do-it-yourself maintenance

Summer tires are high-speed perfor-

WARNING

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.

■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.

Also, do not mix tires of remark-

ably different treadwear.

●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.

●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

7

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

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.393)

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 the tread on snow tires wears

down below 0.16 in. (4 mm)

The effectiveness of the tires as

snow tires is lost.

Tire pressure warning

NOTICE

system

■If tire inflation pressure of

each tire becomes low while

driving

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 continue driving, or your

tires and/or wheels may be

ruined.

Tire rotation

The tire pressure warning sys-

tem of this vehicle adopts a 2-

type warning system.

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.

 When “Adjust Pressure” is

displayed (Normal Warning)

A warning with the tire pressure

warning light and warning buzzer

when there is an unknown level of

low tire pressure with the appear-

ance of the tire due to natural air

leakage as well as the pressure

lowering due to changes in the

pressure according to the outside

temperature.

Do not fail to initialize the tire pres-

sure warning system after tire rota-

tion.

 When “Immediately Check

Tire when Safe” is displayed

(Emergency Warning)

A warning with the tire pressure

warning light and warning buzzer

when there is a known level of low

tire pressure with the appearance

of the tire due to pressure suddenly

■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 posi-

tion 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.

However, the system may not be

able to detect sudden tire ruptures

(bursting, etc.).

 The tire pressure detected by

the tire pressure warning sys-

tem can be displayed on the

multi-information display.

■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 inflation pressure

●It may take a few minutes to dis-

play the tire inflation pressure

after the power switch is turned to

ON. It may also take a few min-

utes to display the tire inflation

pressure after inflation pressure

has been adjusted.

■ How to change the unit

1 Park the vehicle in a safe

place and EV system off.

2 Start the EV system.

WARNING

■Replacing a flat tire

●Do not touch the disc wheels or

the area around the brakes

immediately after the vehicle

has been driven.

After the vehicle has been

driven the disc wheels and the

area around the brakes will be

extremely hot. Touching these

areas with hands, feet or other

body parts while changing a tire,

etc. may result in burns.

• If a wheel bolt hole in a wheel or

the threads of a wheel bolt or

the wheel hub are deformed,

cracked, rusty or otherwise

damaged, have the vehicle

inspected by your Toyota

dealer.

Tire inflation pressure

Inspection and adjust-

ment procedure

Make sure to maintain the

proper tire inflation pres-

sure. 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.555)

Checking the specified

tire inflation pressure

Tire pressure gauge

1 Remove the tire valve cap.

The recommended cold tire

inflation pressure and tire size

are displayed on the tire and

loading information label.

(P.555)

2 Press the tip of the tire pres-

sure 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 infla-

tion pressure measurement

and adjustment, apply soapy

water to the valve and check

for leakage.

■Effects of incorrect tire inflation

pressure

WARNING

■Proper inflation is critical to

save tire performance

Driving with incorrect tire inflation

pressure may result in the following:

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 seri-

ous injury:

●Reduced electricity consumption

●Reduced driving comfort and poor

handling

●Reduced tire life due to wear

●Reduced safety

●Excessive wear

●Uneven wear

●Poor handling

●Damage to the drive train

If a tire needs frequent inflating,

have it checked by your Toyota

dealer.

■Instructions for checking tire

inflation pressure

●Possibility of blowouts resulting

from overheated tires

When checking tire inflation pres-

sure, observe the following:

●Air leaking from between tire

and wheel

●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.

●Wheel deformation and/or tire

damage

●Greater possibility of tire dam-

age while driving (due to road

hazards, expansion joints,

sharp edges in the road, etc.)

●Always use a tire pressure gauge.

It is difficult to judge if a tire is

properly inflated based only on its

appearance.

NOTICE

■When inspecting and adjust-

ing tire inflation pressure

●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.

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.

●Never exceed the vehicle capacity

weight. Passengers and luggage

weight should be placed so that

the vehicle is balanced.
