Chafer 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 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 performance of tires depends 
upon the actual conditions of their use, 
however, and may depart significantly from 
the norm due to variatio ns in driving habits, 
service practices and differences in road 
characteristics and climate.
