ABSTRACT:
The described tread band (1) has laterally opposite transverse channels (6), each having a substantially rectilinear end stretch (6a) extending with an appropriate inclination from a respective outer side edge (1a), a connecting stretch (6c) of curvilinear extension and an inner end stretch (6b) terminating beyond the equatorial plane (X) and having a slightly inclined orientation relative the latter. The connecting stretch (6c) of each transverse channel (6) opens into the connecting stretch of a laterally opposite transverse channel, to define a transverse groove (3) of undulated extension. Also provided are two longitudinal grooves (2) consisting of substantially rectilinear stretches (2a) each extending between two transverse grooves (3) in a direction inclined to the equatorial plane (X). L-shaped auxiliary channels (8) are interposed in an alternate sequence relative to the transverse channels (6) defining grooves (3).
