Uniform Tire Quality Grading
The U.S. National Highway Traffic
Safety Administration has developed a
grading system for evaluating the per-
formance of passenger car tires. The
following information will help you
understand the grading system, which
applies to vehicles sold in the U.S.
Consult your SUZUKI dealer or tire
retailer for help in choosing the correct
replacement tires for your vehicle.
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA Tempera-
ture A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All Passenger Car 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 condi-
tions on a specified government test
course. For example, a tire graded 150
would wear one and one-half (1 1/2)
times as well on the government course
as a tire graded 100. The relative per-
formance 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 climate.
Traction – AA, A, B, C
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 controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING
Replacing the wheels and tires
equipped on your vehicle with
certain combinations of aftermar-
ket wheels and tires can signifi-
cantly change the steering and
handling characteristics of your
vehicle. Oversized tires may also
rub against the fender over
bumps, causing vehicle damage
or tire failure. Therefore, use only
those wheel and tire combina-
tions approved by SUZUKI Motor
Corporation as standard or
optional equipment for your vehi-
cle. For information regarding the
specified tires, refer to the Tire
Information Label located on the
driver’s side door pillar or the
“SPECIFICATIONS” section.
CAUTION
Replacing the original tires with
tires of a different size may result
in false speedometer or odometer
readings. Check with your
SUZUKI dealer before purchas-
ing replacement tires that differ in
size from the original tires.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests, and
does not include acceleration,
cornering, hydroplaning or peak
traction characteristics.
