Maximum tire load
Maximum tire load is the maximum permissible
weight for which the tire is approved.
Locate the maximum tire load on the tire side‐
wall and the Gross Axle Weight Rating – GAWR –
on the certification label on the driver’s door
pillar. Divide the tire load by 1.1. It must be
greater than one-half of the vehicle’s Gross
Axle Weight Rating – GAWR. Note, front vs. rear
GAWR and tire loads, respectively.
Speed letter
Q = up to 100 mph/160 km/h
R = 106 mph/170 km/h
S = up to 112 mph/180 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Tire Identification Number
DOT code: DOT xxxx xxx 3817

Recommendation
Regardless of the tire tread, replace tires at
least every 6 years.

Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
E.g.: Treadwear 200; Traction AA; Temperature
A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger vehicle tires must conform to
Federal Safety Requirements in addition to
these grades.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. E.g., a tire graded 150
would wear one and one-half, 1 g, 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
variations in driving habits, service practices
and differences in road characteristics and cli‐
mate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under control‐
led conditions on specified government test
surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.
The traction grade assigned to this tire is based
on straight-ahead braking traction tests, and
does not include acceleration, cornering, hy‐
droplaning, or peak traction characteristics.
