on lightweight trucks or multipurpose passenger vehicles.
Load rating - the maximum load that a tire is rated to carry for a given inflation pressure.
Maximum load rating - the load rating for a tire at the maximum permissible inflation
pressure for that tire.
Maximum permissible inflation pressure - the maximum cold inflation pressure to
which a tire may be inflated.
Maximum loaded vehicle weight - the sum of curb weight, accessory weight, vehicle
capacity weight, and production options weight.
Outer diameter - the overall diameter of an inflated new tire.
Overall width - the linear distance between the exteriors of the sidewalls of an inflated
tire, including elevations due to labeling, decorations, or protective bands or ribs.
Ply - a layer of rubber-coated parallel cords.
Ply separation - a parting of rubber compound between adjacent plies.
Pneumatic tire - a mechanical device made of rubber, chemicals, fabric and steel or
other materials, that, when mounted on an automotive wheel, provides the traction and
contains the gas or fluid that sustains the load.
Radial ply tire - 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 - the inflation pressure provided by the vehicle
manufacturer on the Tire Information label and on the Certification / VIN tag.
Rim - a metal support for a tire or a tire and tube assembly upon which the tire beads are
seated.
Rim diameter - the nominal diameter of the bead seat.
Rim size designation - the rim diameter and width.
Rim type designation - the industry of manufacturer’s designation for a rim by style or
code.
Rim width - the nominal distance between rim flanges.
Sidewall - that portion of a tire between the tread and bead.
Sidewall separation - the parting of the rubber compound from the cord material in the
sidewall.
Special Trailer (ST) tire - the "ST" is an indication the tire is for trailer use only.
Tread - that portion of a tire that comes into contact with the road.
Tread rib - a tread section running circumferentially around a tire.
Tread separation - pulling away of the tread from the tire carcass.
Treadwear indicators (TWI) - the projections within the principal grooves designed to
give a visual indication of the degrees of wear of the tread.
Vehicle maximum load on the tire - the load on an individual tire that is determined by
distributing to each axle its share of the maximum loaded vehicle weight and dividing by
two.
Vehicle normal load on the tire - the load on an individual tire that is determined by
distributing to each axle its share of the curb weight and dividing by 2.
