• Treadwear The treadwear
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 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.
M. Maximum Inflation
Pressure: Indicates the tire
manufacturers' maximum
permissible pressure or the
pressure at which the maximum
load can be carried by the tire. This
pressure is normally higher than
the vehicle manufacturer's
recommended cold inflation
pressure which can be found on
the Safety Compliance
Certification Label (affixed to
either the door hinge pillar,
door-latch post, or the door edge
that meets the door-latch post,
next to the driver's seating
position), or Tire Label which is
located on the B-Pillar or the edge
of the driver’s door. The cold
inflation pressure should never be
set lower than the recommended
pressure on the vehicle label.
The tire suppliers may have
additional markings, notes or
warnings such as standard load
or radial tubeless.
