The linear distance between the exteriors of the sidewalls of an inflated tire, including elevations due to labeling, decorations, or protective bands or ribs.
A tire intended for use on passenger cars, multipurpose passenger vehicles, and trucks, that have a gross vehicle weight rating (GVWR) of 10,000 lbs (4,535 kg) or less.
A layer of rubber-coated parallel cords.
A parting of rubber compound between adjacent plies.
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.
The combined weight of those installed regular production options weighing over 5.1 lbs (2.3 kg) in excess of those standard items which they replace, not previously considered in curb weight or accessory weight, including heavy duty brakes, ride levelers, roof rack, heavy duty battery, and special trim.
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.
The cold inflation pressure recommended by a vehicle manufacturer.
A tire designed to operate at higher loads and at higher inflation pressures than the corresponding standard tire.
A metal support for a tire or a tire and tube assembly upon which the tire beads are seated.
Nominal diameter of the bead seat.
Rim diameter and width.
The industry of manufacturer's designation for a rim by style or code.
Nominal distance between rim flanges.
The linear distance between the exteriors of the sidewalls of an inflated tire, excluding elevations due to labeling, decoration, or protective bands.
That portion of a tire between the tread and bead.
The parting of the rubber compound from the cord material in the sidewall.
The rim on which a tire is fitted for testing, and it may be any rim listed as appropriate for use with that tire.
That portion of a tire that comes into contact with the road.
A tread section running circumferentially around a tire.
Pulling away of the tread from the tire carcass.
