Tire size(P.377 )
DOT and Tire Identification Number (TIN) ( P.377 )
Location of tread wear indicators ( P.278 )
Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands
which form the plies in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL” is a
bias-ply tire.
“TUBELESS” or “TUBE TYPE”
A tubeless tire does not have a tube and air is directly filled in the tire. A tube
type tire has a tube inside the tire and the tube maintains the air pressure.
Load limit at maximum cold tire inflation pressure ( P.283 )

Uniform tire quality grading
This information has been prepared in accordance with regulations
issued by the National Highway Traffic Safety Ad ministration of the U.S.
Department of Transportation. 
It provides the purchasers and/or prospective purchasers of Lexus vehi -
cles with information on uniform tir
e quality grading.
Your Lexus dealer will help answer any que
stions you may have as you
read this information.
■ DO
T quality grades
All passenger vehicle tires must co nform to F
ederal Safety Require -
ments in addition to these grades. Quality gr
ades can be found where
applicable on the tire sidewall between tread shoulder and maximum
section width.

■Tread wear
The tread wear grade is a comparative rating based on the wear rate of
the tir

e when tested under controll ed conditions on a specified gov -
ernment 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 de pends upon the actual conditions of
their
use, however, and may depart significantly from the norm due to varia -
tions in driving habits, service practices
and differences in road characteris-
tics and climate.
■ Traction AA, A, B, C
The traction grades, from highest to lo
west, are AA, A, B and C, and
they represent the tire’s ability to stop on wet pavement as measured
under controlled condit ions on specified government test surfaces of
asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tir
e is based on braking
(straight ahead) traction tests and does not include cornering (turning) trac-
tion.
