Vehicle specifications
This information has been prepared in accordance with regulations issued by the
National Highway Traffic Safety Administra tion of the U.S. Department of Trans-
portation.
It provides the purchasers and/or prospe ctive purchasers of Lexus vehicles with
information on uniform tire quality grading.
Your Lexus dealer will help answer any ques tions you may have as you read this infor-
mation.
■DOT quality grades
All passenger vehicle tires must conform 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 rati ng based on the wear rate of the tire
when tested under controlled conditio ns 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 actua l conditions of their use.
Performance may differ significantly from the norm due to variations in driving
habits, service practices and difference s in road characteristics and climate.
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C, and they rep-
resent the tire’s ability to stop on wet pavement as measured under controlled
conditions 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 tire is based on braking (straight
ahead) traction tests and does not include cornering (turning) traction.
