1Tire size: For details, see Tire sizeº on page
563.
2DOT and Tire Identification Number (TIN): For
details, see DOT and Tire Identification Number
(TIN)º on page 563.
3Location of the tread wear indicators: For
details, see Checking and replacing tiresº on
page 571.
4Tire ply composition and materials: Plies mean
a layer of rubber-coated parallel cords. Cords
mean the strands forming the plies in the tire.
5Radial tires or bias-ply tires: A radial tire has
RADIALº o the sidewall. The tire not marked
with RADIALº is a bias-ply tire.
6TUBELESSº or TUBE TYPEº: 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.
7Load limit at maximum cold tire inflation
pressure: For details, see Checking and
replacing tiresº on page 571.
8Maximum cold tire inflation pressure: This
means the pressure to which a tire may be
inflated. For details about recommended cold tire
inflation pressure, see Specificationsº on page
553.
9Uniform tire quality grading: For details, see
Uniform tire quality gradingº that follows.
10Summer tire or all season tire: An all season
tire has M+Sº on the sidewall. The tire not
marked with M+Sº is a summer tire. For details,
see Types of tiresº on page 569.

ROTATING TIRES
To equalize tire wear and help extend tire life,
Lexus recommends that you rotate your tires
according to the maintenance schedule. (For
scheduled maintenance information, please refer
to the Owner's Manual Supplement/Scheduled
Maintenanceº.) However, the most appropriate
timing for tire rotation may vary according to your
driving habits and road surface conditions.
The wheel assemblies must be rotated as illustrated
above.
When rotating tires, check for uneven wear and
damage. Abnormal wear is usually caused by
incorrect tire pressure, improper wheel alignment,
out-of-balance wheels, or severe braking.Before storing radial, snow or studded tires, mark the
direction of rotation and be sure to install them in the
same direction when using them again. Tires should
be stored in a cool dry place.

Tire selection
When replacing a tire, use a tire of the same size
and construction, and the same or greater load
capacity as the originally installed tires. Also, all
the tires must be the same brand and have the
same tread patterns.
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.
Check that the maximum load of the replaced 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. As for the maximum load of
the tire, see the load limit at maximum cold tire
inflation pressure mentioned on the sidewall of the tire,
and as for the Gross Axle Weight Ratings (GAWR),
see the Certification Label. For details about
Certification Label and sidewall of the tire, see pages
522 and 561.CAUTION
Observe the following instructions. Otherwise,
an accident may occur resulting in death or
serious injuries.
Do not mix radial, bias belted, or bias-ply tires
on your vehicle, as this may cause dangerous
handling characteristics resulting in loss of
control.
Do not use tires other than the manufacturer's
recommended size, as this may cause
dangerous handling characteristics resulting
in loss of control.
Do not use tires of different brands, sizes,
construction or tread patterns, as this may
cause dangerous handling characteristics
resulting in loss of control.
