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 any autho-
rized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.

■

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.

■

If the tread on snow tires wears down

below 4 mm (0.16 in.)

The effectiveness of the tires as snow tires is

lost.

Tire inflation pressure

●

It may take a few minutes to display the

tire inflation pressure after the power

switch is turned to ON.

It may also take a few minutes to display the
tire inflation pressure after inflation pres-
sure 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.

• 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 tires not equipped with 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 changing

the location of the vehicle as the radio
wave conditions may change.

●

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 operate.

use tire valve caps other than those

specified. The cap may become stuck.

■

To avoid damage to the tire pressure

warning valves and transmitters

When a tire is repaired with liquid seal-

ants, the tire pressure warning valve and

transmitter may not operate properly. If a

liquid sealant is used, contact any author-

ized Lexus retailer or Lexus authorized

repairer, or any reliable repairer or other

qualified service shop as soon as possi-

ble. Make sure to replace the tire pres-

sure warning valve and transmitter when

pressure should be checked at least
once per month. However, Lexus
recommends that tire inflation
pressure be checked once every
two weeks.

WARNING

In order to ensure the performance of

the tires, maintain proper tire inflation

pressure.

If the tires are not properly inflated, the

following may occur:

●

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

After inspecting and adjusting tire infla-

tion pressure, make sure to install the tire

valve caps.

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 accu-
rate cold tire inflation pressure reading.

●

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.

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

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, contact any authorized Lexus
retailer or Lexus authorized repairer, or
any reliable repairer.

■

Wheel bolts

Observe the following precautions to

reduce the risk of death or serious injury:

●

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 any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer. Fail-

ure to follow these precautions 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.
