■

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 with 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.

■

Maximum load of tire

Check that the number given by dividing

the maximum load by 1.10 of the replace-

ment 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. (

P.544)

■

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. (



P.372)

■

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 damage to

parts of the drive train 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.

467

6-3. Do-it-yourself maintenance

Maintenance and

care

Rotate the tires in the order shown.

To equalize tire wear and extend tire life,
Lexus recommends that tire rotation is car-
ried out at the same interval as tire inspec-
tion.

Do not fail to initialize the tire pressure
warning system after tire rotation.

■

When rotating the tires

Make sure that the engine switch is OFF. If

the tires are rotated while the engine switch

is in ON, the tire position information will

not be updated.
If this accidentally occurs, either turn the

engine switch to OFF and then to ON, or

initialize the system after checking that the

tire pressure is properly adjusted.

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



When “Adjust Pressure” is dis-
played (Normal Warning)

The tire pressure warning light comes on
and a buzzer sounds when the tire inflation
pressure becomes low due to natural air
leakage or outside temperature. (Ways of
coping:



P.502, 540)



When “Immediately Check Tire
when Safe” is displayed (Emergency
Warning)

The tire pressure warning light comes on
and a buzzer sounds when the tire inflation
pressure becomes low suddenly due to a
blowout. (Ways of coping:



P.502, 511)

However, the system may not be able to
detect sudden tire ruptures (bursting, etc.).



The tire pressure detected by the
tire pressure warning system can be
displayed on the multi-information

WARNING

●

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.

■

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.

■

Tire inflation pressure

●

It may take a few minutes to display the

tire inflation pressure after the engine

switch is turned to ON. It may also take a

few minutes to display the tire inflation

pressure after inflation pressure has been

adjusted.

●

Tire inflation pressure changes with tem-

perature. The displayed values may also

be different from the values measured

using a tire pressure gauge.

■

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 run-flat 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 wheels 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.

●

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 pres-
sure warning computer and the tire pres-
sure warning system must be initialized.

If the tire inflation pressure settings for the

installed tires change, initialization opera-

tions are required, but if the tire inflation

pressure settings are the same, initializa-

tion is not required.

Drive straight (with occasional left
and right turns) at approximately
25 mph (40 km/h) or more for
approximately 10 to 30 minutes.

Changing a second wheel set is complete

when the tire pressure warning light turns

off and the inflation pressure of each tire is

displayed on the multi-information display.

The recommended cold tire inflation
pressure and tire size are displayed on
the tire and loading information label.

Maintenance and

care

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 drive train

If a tire needs frequent refilling, 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.)

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. (

P.469)

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.

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.
