WARNING

■

When inspecting or replacing the tires

Observe the following precautions.
Failure to do so may lead to damage to the drivetrain or unstable handling.

●

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.

●

Vehicles with an emergency tire puncture repair kit: Do 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.

NOTICE

If tire inflation pressure becomes low while driving, do not continue driving. Otherwise
the tire or wheel may be damaged.

Check if the treadwear indicators are showing on the tires. Also check the tires for
uneven wear, such as excessive wear on one side of the tread.
Check the spare tire condition and pressure if not rotated.

574

INFORMATION

■

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 location 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 seldom
or never been used or damage is not obvious.

■

Maximum load of tire

Check that the number given by dividing the maxi-
mum 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.
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 performance 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 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 adequate
for driving in most winter conditions as well as for use year-round. All season tires,
however, do not have adequate traction performance compared with snow tires in
heavy or loose snow. Also, all season tires fall short in acceleration and handling
performance compared with summer tires in highway driving.

●

Snow tires

8-5. Tire maintenance

575

Maintenance and car

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 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.

■

If the tread on snow tires wears down below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is lost.

576

Run-flat tire features

When run-flat tires are installed, the vehicle can be driven for a maximum of
50 miles (80 km) at a speed below 50 mph (80 km/h) after any tire goes
flat. (However, the vehicle speed may not increase to near 50 mph [80 km/h]
depending on weather or driving conditions.)
Make sure to replace the flat tire before the vehicle has been driven for near 50
miles (80 km). Also, do not use a repaired tire.

A run-flat tire has a

mark on the side wall.

INFORMATION

■

Precautions for run-flat tires

●

The run-flat tires are for only this vehicle. Do not use the tires on other vehicles.

●

Do not mix run-flat tires and normal tires.

●

If non-genuine Lexus wheels are used, it may be impossible to sufficiently demonstrate
the performance of run-flat tires.

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
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
generated in the tire. Do not reduce tire inflation pressure after driving.

●

Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle is balanced.

Checking the specified tire inflation pressure

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

Tire inflation pressure inspection and adjustment procedure

Tire valve

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 recom-
mended 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 adjustment, apply
soapy water to the valve and check for leakage.

Put the tire valve cap back on.

Wheels

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

Wheel selection

When replacing wheels, care should be taken to ensure that they are equivalent to
those removed in load capacity, diameter, rim width and inset

Replacement wheels are available at your Lexus dealer.
Lexus does not recommend using the following:

●

Wheels of different sizes or types

●

Used wheels

●

Bent wheels that have been straightened

INFORMATION

■

When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valves and transmit-
ters 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 pressure warning valves and transmitters must be
installed.

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 the correct wheel bolts for the wheels to be installed.
For details, contact your Lexus dealer.

■

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 tightened, leading to bolt or disc wheel damage. In addition, the oil

WARNING

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 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 accident.

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.

●

Ensure that only genuine Lexus wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with non-genuine
wheels.

Aluminum wheel precautions

Observe the following precautions when handling the aluminum wheels.

●

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

●

When rotating, repairing or changing your tires, check that the wheel bolts are
still tight after driving 621 miles (1000 km).

●

Be careful not to damage the aluminum wheels when using tire chains.

●

Use only Lexus genuine balance weights or equivalent and a plastic or rubber
hammer when balancing your wheels.
