CHECKING TIRE PRESSURE
The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label inside the
glovebox lid.
You should check the tire pressures every two weeks or, at
least once a month. And don’t forget the spare! The pressure
for the spare tire should be 220 kPa (2.2 kg / cm
2 or bar, 32 psi).
Incorrect tire pressure can reduce tire life and make your
vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling,
reduced fuel economy, and the possibility of blowouts from
overheated tires. Also, low tire pressure can cause poor
sealing of the tire bead. If the tire pressure is excessively low,
there is the possibility of wheel deformation and / or tire
separation. So keep your tire pressures at the proper level. If
a tire frequently needs refilling, have it checked by your Lexus
dealer.High tire pressure produces a harsh ride, handling problems,
excessive wear at the center of the tire tread, and a greater
possibility of tire damage from road hazards.
The following instructions for checking tire pressure should be
observed:
The pressure should be checked only when the tires are
cold. If your vehicle has been parked for at least 3 hours and
has not been driven for more than 1.5 km or 1 mile since, you
will get an accurate cold tire pressure reading.
Always use a tire pressure gauge. The appearance of the
tire can be misleading. Besides, tire pressures that are even
just a few pounds off can degrade handling and ride.
Do not bleed or reduce tire pressure after driving. It is
normal for the tire pressure to be higher after driving.
Never exceed the vehicle capacity weight. The
passengers and luggage weight should be located so that
the vehicle is balanced.
Be sure to reinstall the tire inflation valve caps. Without
the valve caps, dirt or moisture could get into the valve core
and cause air leakage. If the caps have been lost, have new
ones put on as soon as possible.

CHASSIS
213 The tires on your Lexus have built-in tread wear indicators to
help you know when the tires need replacement. When the
tread depth wears to 1.6 mm (0.06 in.) or less, the indicators
will appear. If you can see the indicators in two or more
adjacent grooves, the tire should be replaced.
The effectiveness of snow tires is lost if the tread wears
down below 4 mm (0.16 in.).
If you have tire damage such as cuts, splits, cracks deep
enough to expose the fabric, or bulges indicating internal
damage, the tire should be replaced.
If a tire often goes flat or cannot be properly repaired due to the
size or location of a cut or other damage, it should be replaced.
If you are not sure, consult with your Lexus dealer.
If an air loss occurs while driving, do not continue driving with
a deflated tire. Driving even a short distance can damage a tire
beyond repair.
Any tires which are over 6 years old must be checked by
a qualified technician even if damage is not obvious.
Tires deteriorate with age even if they have never or seldom
been used.
This also applies to the spare tire and tires stored for future
use.
Uniform tire quality grading
This information has been prepared in accordance with
regulations issued by the National Highway Traffic Safety
Administration of the U.S Department of Transportation.
It provides the purchasers and / or prospective
purchasers of Lexus vehicles with information on uniform
tire quality grading.
Your Lexus dealer will help answer any questions you may
have as you read this information.
DOT quality grades − All passenger vehicle tires must
conform to Federal Safety Requirements in addition to
these grades. These quality grades are molded on the
sidewall.
Treadwear − The treadwear grade is a comparative rating
based on the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and a half (1-1 / 2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly
from the norm due to variations in driving habits, service
practices and differences in road characteristics and climate.
Traction A, B, C − The traction grades, from highest to lowest,
are A, B and C, and they represent the tire’s ability to stop on
wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt and concrete. A
tire marked C may have poor traction performance.

CHASSIS
214Warning: 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 conditions 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 sudden tire failure. The grade C
corresponds to a level of performance which all passenger car
tires must meet under the Federal 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 grade of this tire is established for
a tire that is properly inflated and not overloaded. Excessive
speed, underinflation, or excessive loading, either separately
or in combination, can cause heat buildup and possible tire
failure.
Tire selection
When replacing a tire, use only the same size and
construction as originally installed and with the same or
greater load capacity.
Using any other size or type of tire may seriously affect
handling, ride, speedometer / odometer calibration, ground
clearance, and clearance between the body and tires or snow
chains.Do not mix radial, belted, or conventional tires on your
vehicle.
It can cause dangerous handling characteristics, resulting in
loss of control. If you need to change from conventional tires
to radial tires or vice versa, replace them as a set.
INSTALLING SNOW TIRES AND
CHAINS
When to use snow tires or chains
Snow tires or chains are recommended when driving on
snow or ice.
On wet or dry roads, conventional or radial tires provide better
traction than snow or studded tires.
Snow tire selection
If you need snow tires, select the same size, construction
and load capacity as the original tires on your Lexus.
Do not use tires other than stated above. 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.

CHASSIS
216Correct replacement wheels are available at your Lexus
dealer.
A wheel of a different size or type may adversely affect
handling, wheel and bearing life, brake cooling,
speedometer / odometer calibration, stopping ability, headlight
aim, bumper height, vehicle ground clearance, and tire or snow
chain clearance to the body and chassis.
ALUMINUM WHEEL
PRECAUTIONS
After driving your vehicle the first 1600 km (1000 miles),
check that the wheel nuts are tight.
If you have rotated, repaired, or changed your tires, check
that the wheel nuts are still tight after driving 1600 km (1000
miles).
When using tire chains, be careful not to damage the
aluminum wheels.
Use only the Lexus wheel nuts and wrench designed for
your aluminum wheels.
When balancing your wheels, use only Lexus balance
weights or equivalent and a plastic or rubber hammer.
As with any wheel, periodically check your aluminum
wheels for damage. If damaged, replace immediately.
