Abstract:
A tire, the speed rating of which is at least V, comprises a tread, having a volumetric void ratio at least equal to 2% and at most equal to 20%, having a central part Pc comprising at least one groove, and two lateral parts PI each having a volumetric void ratio at most equal to 2%. The central part Pc of the tread has an axial width at most equal to one third of the axial width LBDR of the tread, and any portion of the central part Pc of the tread that is circumferentially delimited by two meridian planes separated by a circumferential distance dc equal to one tenth of the outer perimeter P of the tire comprises at least one and at most three grooves that open onto the meridian planes delimiting the portion in question.
