avoid scratching the wheel surface.

Remove any dirt or foreign matter
from the wheel contact surface.

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.

Install the tire and loosely tighten
each wheel nut by hand by approxi-
mately the same amount.

Turn the wheel nuts until the washers come

into contact with the disc wheel.

WARNING

■

When installing the tire

Failure to follow these precautions 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, lead-

ing to bolt or disc wheel damage. In

addition, the oil or grease can cause

the wheel nuts to loosen and the wheel

may fall off, causing a serious accident.

Remove any oil or grease from the

wheel bolts or wheel nuts.

●

Have the wheel nuts tightened with a

torque wrench to 140 N•m (14.3

kgf•m, 103 ft•lbf) as 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

nuts that have been specifically

designed for that wheel.

●

If there are any cracks or deformations

in the bolt screws, nut threads or bolt

holes of the wheel, have the vehicle

inspected by any authorized Lexus

retailer or Lexus authorized repairer,

or any reliable repairer.

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 inflating, have it

checked by any authorized Lexus retailer or

Lexus authorized repairer, or any reliable

repairer.

■

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 1.5 km or 1 mile, 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 gen-

erated in the tire. Do not reduce tire infla-

tion pressure after driving.

●

Passengers and luggage weight should

be placed so that the vehicle is balanced.

Tire inflation pressure

Make sure to maintain proper tire
inflation pressure. Tire inflation
pressure should be checked at least
once per month. However, Lexus
recommends that tire inflation
pressure be checked once every
two weeks.

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.

6-3. Do-it-yourself maintenance

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

: 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 straight-
ened

■

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, the tire

pressure warning valves and transmitters

must be installed. (



P.406)



Use only Lexus wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.

Wheels

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

Wheel selection

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 accident,

causing 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 any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer or

other qualified service shop. In addi-

tion, make sure to purchase your tire

pressure warning valves and transmit-

ters at any authorized Lexus retailer or

Lexus authorized repairer, or any relia-

ble repairer.

●

Ensure that only genuine Lexus wheels

are used on your vehicle.

Tire pressure warning valves and trans-

mitters may not work properly with

non-genuine wheels.
