Abstract

A tread provided with a plurality of cutouts of essentially transverse orientation and characterized in that when new, some of the transverse cutouts form on the running surface hollowed zones of average width Lt greater than or equal to 2 mm and of maximum depth Pt at most equal to 80% of the thickness Pb of tread to become worn, the other transverse cutouts forming on the same running surface incisions of average width Li less than 2 mm and of depth Pi at most equal to Pt. A plurality of the incisions extending by hollowed zones such that after homogenous wear of the tread the volume V1 of the hollowed zones opening on to the new running surface is between 50% and 150% of the volume V0 formed by the hollowed zones when new.
