shaped to fit the rim
Bead separationA breakdown of the bond between components in
the bead
Bias ply tire

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 operat e at higher loads and at
higher inflation pressures than the corresponding
standard tire
GrooveThe space between two adjacent tread ribs
