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.

New tread

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 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.

■

Low profile tires

Generally, low profile tires will wear

more rapidly and tire grip perfor-

mance will be reduced on snowy

and/or icy roads when compared to

standard tires. Be sure to use snow

tires or tire chains on snowy and/or

icy roads and drive carefully at a

speed appropriate for road and

weather conditions.

■

Maximum load of tire

Check that the maximum load 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. (

Tire types

●

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.

●

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.

●

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

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.210)

■

If the tread on snow tires wears

down below 0.16 in. (4 mm)

The effectiveness of the tires as

snow tires is lost.

■

Checking the tire valves

When replacing the tires, check the

tire valves for deformation, cracks,

and other damage.

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.

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.

Rotate the tires in the order
shown.

Front

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 pres-
sure warning system after tire rota-
tion.

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.
The tire pressure warning sys-
tem of this vehicle adopts a
2-type warning system.

NOTICE

■

Low profile tires

Low profile tires may cause

greater damage than usual to the

tire wheel when sustaining impact

from the road surface. Therefore,

pay attention to the following:

●

Be sure to use proper tire infla-

tion pressure. If tires are

under-inflated, they may be

damaged more severely.

●

Avoid potholes, uneven pave-

ment, curbs and other road haz-

ards. Failure to do so may lead

to severe tire and wheel dam-

age.

■

If tire inflation pressure of

each tire becomes low while

driving

Do not continue driving, or your

tires and/or wheels may be

ruined.

■

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.

play the tire inflation pressure

after the engine 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.

●

Tire inflation pressure changes

with temperature.

The displayed values may also be

different from the values mea-

sured using a tire pressure gauge.

■

Situations in which the tire

pressure warning system may

not operate properly

●

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

plant, gas station, radio station,

large display, airport or other facil-

ity that generates strong radio

waves or electrical noise.

• 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 condi-

tions.

●

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.

■

Warning performance of the tire

pressure warning system

The warning of the tire pressure

warning system will change in

accordance with driving conditions.

For this reason, the system may

give a warning even if the tire pres-

sure 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 replacing tires or wheels,
tire pressure warning valves and
transmitters must also be
installed.
When new tire pressure warning
valves 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. Have tire pressure
warning valves and transmitter
ID codes registered by your Toy-
ota dealer. (
