■

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.

■

Proper storage of the spare tire

As an improperly stored spare tire

may cause damage to the wire

cable that holds it, check that the

spare tire is stored properly on a

daily basis.

●

If the stored spare tire appears to

be slanted or rattles while driving,

the spare tire may not be properly

stored. Store the spare tire again

by performing the following tire

change procedure correctly:

If the spare tire is slanted, the

hoist assembly may be stuck in

the wheel opening. If the spare

tire rattles while driving, it may

not be fully raised. Lower the

spare tire to the ground and

make sure that the hoist assem-

bly is perpendicular to the wheel

opening.

Raise the tire slowly and steadily

until a click is heard and the jack

handle skips.

If the spare tire cannot be lowered,

the wire cable may be severed.

Have the vehicle inspected at your

Toyota dealer.

■

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. (

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

395

6-3. Do-it-yourself maintenance

Maintena

a

nd ca

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.314)

■

If the tread on snow tires wears

down below 0.16 in. (4 mm)

The effectiveness of the tires as

snow tires is lost.

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.

●

Vehicles with a compact spare

tire: Do not tow if your vehicle

has a compact spare tire

installed.

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.

■

Warning performance of the tire

pressure warning system

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 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. (

tires, initialization will be completed

in approximately 10 to 30 minutes. If

initialization is not complete after

driving approximately 10 to 30 min-

utes, continue driving for a while.
If the inflation pressure of each tire

is not displayed after driving for

approximately 1 hour, perform the

following procedure.

●

Park the vehicle in a safe place for

approximately 20 minutes. Then

drive straight (with occasional left

and right turns) at approximately

25 mph (40 km/h) or more for

approximately 10 to 30 minutes.

However, in the following situations,

the tire inflation pressure will not be

recorded and the system will not

operate properly. Perform initializa-

tion again.

●

If the vehicle is reversed during

initialization, the data up to that

point is reset, so perform the ini-

tialization procedure again from

the beginning.

●

When operating the tire pressure

warning reset switch, the tire pres-

sure warning light does not blink 3

times.

●

After performing initialization, the

tire pressure warning light blinks

for 1 minute then stays on while

driving.

If the inflation pressure of each tire

is still not displayed, have the vehi-

cle inspected by your Toyota dealer.
