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.

IWhen to replace your vehicle’s

tires

Tires should be replaced if:

GThe treadwear indicators are

showing on a tire.

GYou have tire damage such as

cuts, splits, cracks deep enough

to expose the fabric, and bulges

indicating internal damage

GA 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.

GAll 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.

ITire 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.

IMaximum 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.

GSnow 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.349)

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.513)

WARNING

NOTICE

IWhen inspecting or replacing

tires

IDriving on rough roads

Take particular care when driving

on roads with loose surfaces or

potholes.

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.

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.

GDo not mix tires of different

makes, models or tread pat-

terns.

Also, do not mix tires of remark-

ably different treadwear.

IIf tire inflation pressure of

each tire becomes low while

driving

Do not continue driving, or your

tires and/or wheels may be

ruined.

GDo not use tire sizes other than

those recommended by Toyota.

GDo not mix differently con-

structed tires (radial, bias-belted

or bias-ply tires).

Tire rotation

Rotate the tires in the order

shown.

GDo not mix summer, all season

and snow tires.

GDo 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.

GDo not tow anything if a tire that

has been repaired using the

emergency tire puncture repair

kit is installed. The load on the

tire may cause unexpected

damage to the tire.

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 foreign matter is on the wheel

contact surface, the wheel nuts

may loosen while the vehicle is in

motion, causing the tire to come off.

GFailure to follow these precau-

tions could cause the wheel

nuts to loosen and the tire to fall

off, resulting in death or serious

injury.

• Never use oil or grease on the

wheel bolts or wheel nuts.

Oil and grease may cause the

wheel nuts to be excessively

tightened, leading to bolt or disc

wheel damage. Remove any oil

or grease that has adhered

when installing the wheel nuts.

2 Install the tire and loosely

tighten each wheel nut by

hand by approximately the

same amount.

Turn the wheel nuts until the wash-
