The recommended cold tire inflation pressures,
tire sizes and the combined weight of occupants
and cargo (vehicle capacity weight) are described
o n page ccclxv, ccclxvi and cdxiii. They are also described
on the tire and loading information label as
shown.
You should check the tire inflation pressure every two
weeks, or at least once a month. And do not forget
the spare!
The following instructions for checking tire
inflation 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 inflation pressure reading.
Always use a tire pressure gauge. The
appearance of a tire can be misleading. Besides,
tire inflation pressures that are even just a few
pounds off can degrade handling and ride.
Do not bleed or reduce tire inflation pressure
after driving. It is normal for the tire inflation
pressure to be higher after driving.
Never exceed the vehicle capacity weight.
Passengers and luggage weight should be located
so that the vehicle is balanced.

Inspection and adjustment procedure
1Tire valve
2Tire pressure gauge
1. Remove the tire valve cap.
2. Press the tip of the tire pressure gauge to the tire
valve.
3. Read the pressure using the graduations of the
gauge.
4. In case the tire inflation pressure is not within the
prescribed range, insert the compressed air from the
valve. In case of applying too much air, press the
center of the valve and release the air to adjust. 5. After completing the tire inflation pressure
measurement and adjustment, apply soapy water to
the valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not available, have your
vehicle checked by your Lexus dealer.
CAUTION
Be sure to reinstall the tire 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.
Incorrect tire inflation pressure may waste fuel, reduce
the comfort of driving, reduce tire life and make your
vehicle less safe to drive.
If a tire frequently needs refilling, have it checked by
your Lexus dealer.

CAUTION
Keep your tires properly inflated. Otherwise, the
following conditions may occur and cause an
accident resulting in death or serious injuries.
Low tire pressure (underinflation) —
Excessive wear
Uneven wear
Poor handling
Possibility of blowouts from an overheated
tire
Poor sealing of the tire bead
Wheel deformation and/or tire separation
A greater possibility of tire damage from road
hazards
High tire pressure (overinflation) —
Poor handling
Excessive wear
Uneven wear
A greater possibility of tire damage from road
hazards

1Summer tire or all season tire: An all season
tire has “M+S” on the sidewall. The tire not
marked with “M+S” is a summer tire. For details,
see “Types of tires” on page ccclxxxii.
2Tire size: For details, see “Tire size” on page ccclxxv.
3DOT and Tire Identification Number (TIN): For
details, see “DOT and Tire Identification Number
(TIN)” on page ccclxxv.
4Uniform tire quality grading: For details, see
“Uniform tire quality grading” that follows.
5Location of the tread wear indicators: For
details, see “Checking and replacing tires” on
page ccclxxxiv.
6Tire ply composition and materials: Plies mean
a layer of rubber −coated parallel cords. Cords
mean the strands forming the plies in the tire.
7Radial tires or bias ply tires: A radial tire has
“RADIAL” on the sidewall. A tire not marked with
“RADIAL” is a bias−ply tire.
8“TUBELESS” or “TUBE TYPE”: A tubeless tire
does not have a tube inside the tire. A tube type
tire has a tube inside the tire and the tube
maintains the air pressure.
9Load limit at maximum cold tire inflation
pressure: For details, see “Checking and
replacing tires” on page ccclxxxiv.
10Maximum cold tire inflation pressure: This
means the pressure to which a tire may be
inflated. For details about recommended cold tire
inflation pressure, see “Specifications” on page
ccclxiii.

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 for this tire
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.
