Maintenance and care ■
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 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. ( → P.459)
■
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 recom-
mended. 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 accelerati on and handling per-
formance compared 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 instal led 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 regula-
tions for possible restrictions. Snow tires
should be installed on all wheels.
( → P.299) ■
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.

392 6-3. Do-it-yourself maintenance
LS500_OM_OM50F54U_(U) When replacing the tires or wheels, the
tire pressure warning valve and trans-
mitters must be installed to the wheels
which will be installed to the vehicle.
When new tire pressure warning
valves and transmitte rs are installed,
new ID codes must be registered in the
tire pressure warning computer and
the tire pressure warning system must
be initialized. ( → P.394)■
Replacing tires and wheels
If the ID codes of the tire pressure warning
valve and transmitters are not registered,
the tire pressure warning system will not
work properly. In this case, after driving for
about 20 minutes, the tire pressure warning
light will blink for ap proximately 1 minute
and then illuminate to indicate a system
malfunction. ■
The tire pressure warning system
must be initialized in the following
circumstances:
 When the tire inflation pressure is
changed such as when changing
traveling speed or load weight.
 When the tire inflation pressure is
changed such as when the tire size
is changed.
 When rotating the tires.
 After performing the transmitter ID
code registration procedure.
( → P.394)
When the tire pressure warning system
is initialized, the current tire inflation
pressure is set as the benchmark pres-
sure. ■
How to initialize the tire pressure
warning system
1 Park the vehicle in a safe place and
turn the engine switch off. The initialization pr ocedure cannot be
started while the vehicle is moving.
2 Adjust the tire inflation pressure to
the specified cold tire inflation pres-
sure level. Make sure to adjust the tire pressure to the
specified cold tire infl ation pressure level.
The tire pressure warning system will oper-
ate based on this pressure level.
3 Turn the engine switch to IGNI-
TION ON mode.
4 Press or of the meter con-
trol switch to select .Installing tire pressure warning
valves and transmitters
NOTICE■
Repairing or replacing tires, wheels,
tire pressure warning valves, trans-
mitters and tire valve caps●
When removing or fitting the wheels,
tires or the tire pressure warning
valves and transmitters, contact your
Lexus dealer as the tire pressure warn-
ing valves and transmitters may be
damaged if not handled correctly.
●
Make sure to install the tire valve caps.
If the tire valve caps are not installed,
water may enter the valves of the tire
pressure warning valve and transmit-
ters and the valves may become stuck.
●
When replacing tire valve caps, do not
use tire valve caps other than those
specified. The cap may become stuck. Initializing the tire pressure
warning system

400 6-3. Do-it-yourself maintenance
LS500_OM_OM50F54U_(U) 1 Remove the tire valve cap.
2 Press the tip of the tire pressure
gauge onto the tire valve.
3 Read the pressure using the gauge
gradations.
4 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.
5 After completing the tire inflation
pressure measurem ent and adjust-
ment, apply soapy water to the
valve and check for leakage.
6 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 ti re 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 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 in flation 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 ti re inflation pressure
to be higher after driving as heat is gen-
erated 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 on 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.

Maintenance and care 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 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 valv es and transmitters
must be installed. ( → P.392)  Use only Lexus wheel nuts and
wheel nut wrenches designed for
use with your aluminum wheels.
 When rotating, repairing or chang-
ing your tires, check that the wheel
nuts are still tight after driving 1000
miles (1600 km).
 Be careful not to damage the alumi-
num wheels when using tire chains.
 Use only Lexus genuine balance
weights or equivalent and a plastic
or rubber hammer when balancing
your 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 your Lexus
dealer or other qua lified 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 trans-
mitters may not work properly with
non-genuine wheels.

Traction AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C, and they
represent the tire’s ability to stop on
wet pavement as measured under con-
trolled conditions on specified govern-
ment test surfaces of asphalt and
concrete. A tire marked C may have poor traction
performance.
Warning: The traction grade assigned to
this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction. ■
Temperature A, B, C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temperature
can lead to sudd en tire failure.
Grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Fede ral Motor Vehicle
Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades of a tire
assume that it is prop erly inflated and not
overloaded.
Excessive speed, unde rinflation, or exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
