It provides the purchasers and/or pro-
spective 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 con-
form to Federal Safety Requirements in
addition to these grades. Quality
grades can be found where applicable
on the tire sidewall between tread
shoulder and maximum section width. For example: Treadwear 200 Traction AA
Temperature A ■
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions 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 performa nce of tires depends
upon the actual conditions of their use.
Performance may differ significantly from
the norm due to variatio ns in driving habits,
service practices and differences in road
characteristics and climate.Tire section names A
