Maximum (permissible) inflation pressure means the maximum cold inflation pressure to
which a tire may be inflated. Also called "max imum inflation pressure."
Normal occupant weight
means
150 lbs. (68 kilograms) times the number
of occupants seated in the vehicle up to the total seating capacity of your vehicle.
Outer diameter
means the overall diameter of an inflated new
tire.
Overall width means the linear distance between the exteriors
of the sidewalls of an inflated tire, including ele
vations due to labeling, decorations, or protec tive bands or ribs.
Ply
means a layer of rubber-coated parallel cords.
Radial ply tire
means a pneumatic tire in which the ply cords
that extend to the beads are laid at substantially
90 degrees to the centerline of the tread.
Recommended inflation pressure
see
52, "Cold tire inflation pressure".
Rim
means a metal support for a tire or a tire and
tube assembly upon which the tire beads are
seated.
Rim diameter
means nominal diameter of the bead seat . If you
change your wheel size, you will have to pur
chase new tires to match the new rim diameter.
Rim size designation
means rim diameter and width.
Rim width
means nominal distance between rim flanges.
Sidewall
means that portion of a tire between the tread

Booklet 3.2 Tips and Advice
Speed rating (letter code) means the speed at which a tire is designed to be
driven for extended periods of time. The ratings range from 93 mph (150 km/h) to 186 mph
(298 km/h). These ratings are listed in the table
below 62. You may not find this informa
tion on all tires because it is not required by law.
The speed rating letter code, where applicable, is molded on the tire sidewall and indicates the
maximum permissible road speeds.
Tire pressure monitoring system
1 )
means a system that detects when one or more
of a vehicle's tires are underinflated and illumi nates a low tire pressure warning telltale.
Tread means that portion of a tire that comes into con
tact with the road.
Tread separation means pulling away of the tread from the tire
carcass.
Tread wear indicators (TWI) means the projections within the principal
grooves designed to give a visual indication of
the degrees of wear of the tread. See
59, "Tread Wear Indicator (TWI)" for more informa
tion on measuring tire wear.
Uniform Tire Quality Grading
is a tire information system developed by the United States National Highway Traffic Safety
Administration (NHTSA) that is designed to help buyers make relative comparisons among tires.
The UTQG is not a safety rating and not a guar antee that a tire
will last for a prescribed number
of miles or perform in a certain way. It simply
gives tire buyers additional information to com bine with other considerations, such as price,
brand loyalty and dealer recommendations .
Under UTQG, tires are graded by the tire manu
facturers in three areas: tread wear, traction and temperature resistance. The UTQG information
on the tires, molded into the sidewalls.
