mum air pressure information is
specified on a tire side wall.
Maximum Load Rating: The load-
ing capacity for a tire, which is inflat-
ed to the maximum.
Maximum Loaded Vehicle Weight:
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight: The mul-

ously considered in curb weight or
accessory weight, including heavy
duty brakes, ride levelers, roof rack,
heavy duty battery, and special trim.
Recommended Inflation Pressure:
Vehicle manufacturer's recommend-
ed pressure to inflate a tire. This is
specified on a tire placard.
Radial Ply Tire: A pneumatic tire in
which the ply cords that extend to the

ed.
Sidewall: The portion of a tire
between the tread and the bead.
Speed Rating: An alphanumeric
code to indicate the maximum speed
to which a tire can operate.
Traction: The friction between a tire
and a road surface. The amount of
grip provided.
Tread: The contacting portion of a
tire with the road.
Treadwear Indicators: This is a nar-
row band, sometimes called "wear
bars." This appears across the tread,
when only 2/32 inch of tread
remains.
UTQGS: The Uniform Tire Quality
Grading Standards is the information
of traction, temperature and tread
abrasion. A rating is measured by a
tire manufacturer in accordance with
the government-specified testing
procedure. The rating information is
specified on the tire side wall.
