Bias ply tire
A pneumatic tire in which the ply cords that
extend to the beads are laid at alternate
angles substantially less than 90 degrees to
the centerline of the tread
CarcassThe tire structure, except tread and sidewall
rubber which, 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
CT

and rim system in which the rim is designed
with rim flanges pointed radially inward and
the tire is designed to fit on the underside of
the rim in a manner that encloses the rim
flanges inside the air cavity of the tire
Extra load tire
A tire designed to operate at higher loads and
at higher inflation pressures than the corre-
sponding standard tire
GrooveThe space between two adjacent tread ribs
Innerliner
The layer(s) forming the inside surface of a
tubeless tire that contains the inflating medium
within the tire
Innerliner separationThe parting of the innerliner from cord material
in the carcass
Intended outboard
sidewall
(a) The sidewall that contains a whitewall,
bears white lettering, or bears manufac-
turer, brand, and/or model name molding
that is higher or deeper than the same
molding on the other sidewall of the tire, or
