Title: TREAD COMPRISING A LONG TREAD BAR HAVING A PLURALITY OF CUT-OUTS
Abstract:
The invention relates to a tread for a pneumatic tyre, comprising a long tread bar (3) extending in a circumferential direction and comprising a contact surface (5) that comes into contact with the ground, a first and a second side wall defining said contact surface (5), the long tread bar comprising a plurality of incisions which each have a first and a second end. The incisions (n, n+1) are successively arranged longitudinally on the contact surface (5) in such a way that when an incision (n) reaches its second end, another incision (n+1) starts, at the same circumferential level on the long tread bar (3). Furthermore, from a certain depth in the tread, the incisions (n, n+1) at least partially widen.
