Vehicle normal load on the
tireLoad on an individual tire that is determined by distributing to each axle its share of
the curb weight, accessory weight, and normal occupant weight and dividing by two.
Pneumatic Radial Tire Definitions
Bead separationA breakdown of the bond between components in the bead.Bias ply tireA pneumatic tire in which the ply cords that extend to the beads are laid at alternate angles
substantially less than 90 degrees to the center line of the tread.CarcassThe tire structure, except tread and sidewall rubber which, that when inflated, bears the load.ChunkingThe breaking away of pieces of the tread or sidewall.CordThe strands forming the plies in the tire.Cord separationThe parting of cords from adjacent rubber compounds.CrackingAny parting within the tread, sidewall, or inner liner of the tire extending to cord material.Extra load tireA tire designed to operate at higher loads and higher inflation pressure than the
corresponding standard tire.GrooveThe space between two adjacent tread ribs.Inner linerThe layer(s) forming the inside surface of a tubeless tire that contains the inflating medium
within the tire.Inner liner
separationThe parting of the inner liner from cord material in the carcass.Load ratingThe maximum load that a tire is rated to carry for a given inflation pressure.Maximum load
ratingThe load rating for a tire at the maximum permissible inflation pressure for that tire.Measuring rimThe rim on which a tire is fitted for physical dimension requirements.Open spliceAny parting at any junction of tread, sidewall, or inner liner that extends to the cord material.Outer diameterThe overall diameter of an inflated new tire.Overall widthThe linear distance between the exteriors of the sidewalls of an inflated tire, including
elevations due to labeling, decorations, or protective bands or ribs.PlyA layer of rubber-coated parallel cords.Ply separationA parting of rubber compound between adjacent plies.Pneumatic tireA 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 tireA pneumatic tire in which the ply cords that extend to the beads are laid at substantially 90
degrees to the center line of the tread.Reinforced tireA tire designed to operate at higher loads and at higher inflation pressures than the
corresponding standard tire.Section widthThe linear distance between the exteriors of the sidewalls of an inflated tire, excluding
elevations due to labeling, decoration, or protective bands.SidewallThe portion of a tire between the tread and bead.Sidewall separationThe parting of the rubber compound from the cord material in the sidewall.
