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 cannot be

properly repaired due to the size or loca-

tion of a cut or other damage

If you are not sure, consult your Lexus

dealer.

■

Tire life

Any tire over 6 years old must be checked

by a qualified technician even if it has sel-

dom or never been used or damage is not

obvious.

■

Low profile tires (21-inch tires)

Generally, low profile tires will wear more

rapidly and tire grip performance will be

reduced on snowy and/or icy roads when

compared to standard tires. Be sure to use

snow tires 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, which-

ever 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 driv-

ing under dry conditions. Since summer

tires do not have the same traction per-

formance as snow tires, summer tires are

inadequate for driving on snow-covered

or icy roads. For driving on snow-cov-

ered roads or icy roads, the use of snow

tires is recommended. When installing

snow tires, be sure to replace all four

tires.

●

All season tires

All season tires are designed to provide

better traction in snow and to be ade-

quate for driving in most winter condi-

tions as well as for use year-round. All

season tires, however, do not have ade-

quate 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, construction and load capacity

as the originally installed tires. Since your

vehicle has radial tires as original equip-

ment, 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. (

Tires cannot be rotated.

Your vehicle is equipped with a tire
pressure warning system that uses tire
pressure warning valves and transmit-
ters to detect low tire inflation pressure
before serious problems arise.



If the tire pressure drops below a
predetermined level, the driver is
warned by a screen display and a
warning light. (



The tire pressure detected by the
tire pressure warning system can be

WARNING

■

When inspecting or replacing tires

Observe the following precautions to

prevent accidents.

Failure to do so may cause damage to

parts of the drivetrain as well as danger-

ous handling characteristics, which may

lead to an accident resulting in death or

serious injury.

●

Do not mix tires of different makes,

models or tread patterns.

Also, do not mix tires of remarkably

different treadwear.

●

Do not use tire sizes other than those

recommended by Lexus.

●

Do not mix differently constructed

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 previously.

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 cushion-

ing ability of the tires. In addition, driving

on rough roads may cause damage to

the tires themselves, as well as the vehi-

cle’s wheels and body.

■

Low profile tires (21-inch tires)

Low profile tires may cause greater dam-

age 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 inflation

pressure. If tires are under-inflated,

they may be damaged more severely.

●

Avoid potholes, uneven pavement,

curbs and other road hazards. Failure

to do so may lead to severe tire and

wheel damage.

■

If tire inflation pressure of each tire

becomes low while driving

Do not continue driving, or your tires

and/or wheels may be ruined.

checks. Make sure to check tire inflation

pressure as part of your routine of daily

vehicle checks.

■

Situations in which the tire pressure

warning system may not operate prop-

erly

●

In the following cases, the tire pressure

warning system may not operate prop-

erly.

• If non-genuine Lexus 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 tire is equipped.

• If a window tint that affects the radio wave

signals is installed.

• If there is a lot of snow or ice on the vehi-

cle, particularly around the wheels or

wheel housings.

• If the tire inflation pressure is extremely

higher than the specified level.

• If wheel without tire pressure warning

valves and transmitters are used.

• If the ID code on the tire pressure warn-

ing valves and transmitters is not regis-

tered in the tire pressure warning

computer.

●

Performance may be affected in the fol-

lowing situations.

• Near a TV tower, electric power plant,

gas station, radio station, large display,

airport or other facility 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 conditions.

●

When the vehicle is parked, the time

taken for the warning to start or go off

could be extended.

●

When tire inflation pressure declines rap-

idly for example when a tire has burst, the

warning may not function.

When replacing tires or wheels, tire
pressure warning valves and transmit-
ters 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. (

warning system determines the position.

Drive the vehicle at approximately
25mph (40 km/h) or more for
approximately 10 to 30 minutes.

When initialization is complete, the infla-

tion pressure of each tire will be displayed

on the multi-information display.
Depending on the vehicle and driving con-

ditions, initialization may take up to

approximately 1 hour to complete.

■

The initialization operation

●

Make sure to carry out initialization after

adjusting the tire inflation pressure.

Also, make sure the tires are cold before

carrying out initialization or tire inflation

pressure adjustment.

●

If you have accidentally turned the engine

switch <power switch> off during initial-

ization, it is not necessary to manually

restart the initialization again, as initializa-

tion will restart automatically the next

time the engine switch <power switch> is

turned to ON.

●

If you accidentally perform initialization

when initialization is not necessary, adjust

the tire inflation pressure to the specified

level when the tires are cold, and conduct

initialization again.

●

While the position of each tire is being

determined and the inflation pressures

are not being displayed on the multi-

information display, if the inflation pres-

sure of a tire drops, the tire pressure

warning light will come on.

■

When initialization of the tire pressure

warning system has failed

Initialization may take longer to complete if

the vehicle is driven on an unpaved road.

When performing initialization, drive on a

paved road if possible. Depending on the

driving environment and condition of the

tires, initialization will be completed in

approximately 10 to 30 minutes. If initializa-

tion is not complete after driving approxi-

mately 10 to 30 minutes, continue driving

for a while. If the inflation 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. Per-
form initialization again.

●

When performing initialization, the tire

pressure warning light does not blink 3

times. (Initialization will not occur while

driving)

●

After performing initialization, the tire

pressure warning light blinks for 1 minute

then stays on after driving for about 20

minutes.

If the inflation pressure of each tire is still not
displayed, have the vehicle inspected by
your Lexus dealer.

Replacing a 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.

●

When removing or installing a tire,

make sure to use the guide pin. Also,

the guide pin is made of resin. It may

be damaged if the wheel is placed any-
where other than

or if a large

amount of force is applied to the guide

pin.

●

Failure to follow these precautions

could cause the wheel bolts to loosen

and the tire to fall off, resulting in death

or serious injury.

• The contact surfaces of the wheel bolt

and wheel are designed specifically to

fit together. When using wheels that

were installed when the vehicle was

shipped from the factory, use special-

ized Lexus genuine wheel bolts. Do

not use wheel bolts designed for other

models, model years or types even if

they are Lexus genuine parts. If the

vehicle does not have wheels that

were installed to the vehicle when it

was shipped from the factory, the fac-

tory-installed wheel bolts may not be

appropriate for the wheel. Contact

either the retailer where the wheels

were purchased or the manufacturer

of the wheels for proper installation

advice.

addition, the oil or grease can cause

the wheel bolts to loosen and the

wheel may fall off, causing a serious

accident. Remove any oil or grease

from the wheel bolts.

●

Have the wheel bolts tightened with a

torque wrench to 103.3 ft•lbf (140

N•m, 14.3 kgf•m) soon as possible

after changing wheels.

●

Do not attach a heavily damaged

wheel ornament, as it may fly off the

wheel while the vehicle is moving.

●

When installing a tire, only use wheel

bolts that have been specifically

designed for that wheel.

●

If there are any cracks or deformations

in the bolt screws, bolt threads or bolt

holes of the wheel, have the vehicle

inspected by your Lexus dealer.

■

After using the tools

Before driving, make sure all the tools

are stored securely in place. Failure to do

so may cause injury in case of a collision

or sudden braking.

Tire pressure gauge

Remove the tire valve cap.

Press the tip of the tire pressure
gauge onto the tire valve.

Read the pressure using the gauge
gradations.

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.

After completing the tire inflation
pressure measurement and adjust-
ment, apply soapy water to the
valve and check for leakage.

Put the tire valve cap back on.

■

Tire inflation pressure check interval

You should check tire inflation pressure

every two weeks, or at least once a month.

Do not forget to check the spare.

■

Effects of incorrect tire inflation pres-

sure

Driving with incorrect tire inflation pressure

may result in the following:

●

Reduced fuel economy

●

Reduced driving comfort and poor han-

dling

●

Reduced tire life due to wear

●

Reduced safety

●

Damage to the drivetrain

If a tire needs frequent inflating, have it

checked by your Lexus dealer.

■

Instructions for checking tire inflation

pressure

When checking tire inflation pressure,

observe the following:

●

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 read-

ing.

●

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 gener-

ated in the tire. Do not reduce tire infla-

tion pressure after driving.

●

Never exceed the vehicle capacity

weight.

Passengers and luggage weight should

be placed so that the vehicle is balanced.

WARNING

■

Proper inflation is critical to save tire

performance

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 serious injury:

●

Excessive wear

●

Uneven wear

●

Poor handling

●

Possibility of blowouts resulting from

overheated tires

●

Air leaking from between tire and

wheel

●

Wheel deformation and/or tire dam-

age

●

Greater possibility of tire damage

while driving (due to road hazards,

expansion joints, sharp edges in the

road, etc.)

NOTICE

■

When inspecting and adjusting tire

inflation pressure

Be sure to put the tire valve caps back

on.

If a valve cap is not installed, dirt or mois-

ture may get into the valve and cause an

air leak, resulting in decreased tire infla-

tion pressure.

When replacing wheels, care should
be taken to ensure that they are equiv-
alent to those removed in load capac-
ity, diameter, rim width and inset

Replacement wheels are available at
your Lexus dealer.

: Conventionally referred to as offset.

Lexus does not recommend using the
following:



Wheels of different sizes or types



Used wheels



Bent wheels that have been
straightened

■

When replacing wheels

The wheels of your vehicle are equipped

with tire pressure warning valves and trans-

mitters that allow the tire pressure warning

system to provide advance warning in the

event of a loss in tire inflation pressure.

Whenever wheels are replaced, tire pres-

sure warning valves and transmitters must

be installed. (

Wheels

If a wheel is bent, cracked or heav-
ily corroded, it should be replaced.
Otherwise, the tire may separate
from the wheel or cause a loss of
handling control.

WARNING

■

When replacing wheels

●

Do not use wheels that are a different

size from those recommended in the

Owner’s Manual, as this may result in a

loss of handling control.

●

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.

●

Use the correct wheel bolts for the

wheels to be installed. For details, con-

tact your Lexus dealer.

■

Wheel bolts

●

Do not over tighten.

●

Never use oil or grease on the wheel

bolts. Oil and grease may cause the

wheel bolts to be excessively tight-

ened, leading to bolt or disc wheel

damage. In addition, the oil or grease

can cause the wheel bolts to loosen

and the wheel may fall off, causing a

serious accident. Remove any oil or

grease from the wheel bolts.

●

If there are any cracks or deformations

in the wheel bolts, or if the surface

treatment becomes worn, have the

wheel bolts replaced at your Lexus

dealer. Failure to follow these precau-

tions could cause the wheel bolts to

loosen and the tire to fall off, resulting

in death or serious injury.

■

Use of defective wheels prohibited

Do not use cracked or deformed wheels.

Doing so could cause the tire to leak air

during driving, possibly causing an acci-

dent.

NOTICE

■

Replacing tire pressure warning

valves and transmitters

●

Because tire repair or replacement

may affect the tire pressure warning

valves and transmitters, make sure to

have tires serviced by your Lexus

dealer or other qualified service shop.

In addition, make sure to purchase

your tire pressure warning valves and

transmitters at your Lexus dealer.
