Tread Wear, Traction and Temperature
Grades
Tr ea d w ea r : The tread wear grade is a
comparative rating based on the wear
rate of the tire when tested under
controlled conditions 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.
Traction: The traction grades, from
highest to lowest are AA, A, B, and C.
The grades represent 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.
Temperature: The temperature grades
are A (the highest), B and C,
representing the tire's resistance to the
generation of heat and its ability to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local
governments may require true snow
tires, those with very deeply cut tread.
These tires should only be used in pairs
or placed on all four wheels. Make
sure you purchase snow tires that are
the same size and construction type as
the other tires on your vehicle.
SAFETY WARNING
The following safety warning appears
on the tire's sidewall.

T115/70D16 90M is an example of a
tire size and load index rating. Here is
an explanation of the various
components of that tire size and load
index rating. Note that the tire size and
load index rating may be different from
the example.
T
Indicates a tire that may be installed on
cars, SUVs, minivans and light trucks as
designated by the Tire and Rim
Association (T&RA).
115
“115” is the nominal width of the tire
in millimeters. This three-digit number
gives the width in millimeters of the
tire from sidewall edge to sidewall
edge. In general, the larger the
number, the wider the tire.
70
“70” is the aspect ratio. This two-digit
number indicates the tire's ratio of
height to width.
D
“D” is the tire construction symbol. D
indicates “diagonal ply construction”.
16
“16” is the wheel rim diameter in
inches.
90
“90” is the Load Index. This two-or
three-digit number indicates how
much weight each tire can support.
M
“M” is the speed rating. The speed
rating denotes the maximum speed for
which the use of the tire is rated.
Letter Rating Speed Rating
M 81 mph
