Abstract

Tyre in which the widths of the carcass zones beneath the tread breaker between the underlay and the ends of the sidewall cords, and the height reached by the plies doubled round the bead wires are all approx. equal. Pref. the reinforcing plies are laid up flat to form a more acute angle 'Y' w.r.t. the circumferential axis beneath the tread underlay than the angle of lay-up 'X' for traversing the sidewalls. X = 30-80, pref. >40 degrees. Pref. the tread underlay plies are laid up 10-25 degrees.
