• and
• a belt structure disposed radially between the carcass ply and the tread, the belt structure comprising at least one belt layer and an overlay comprising at least one overlay layer, the overlay layer being disposed radially between the at least one belt layer and the radially innermost surface of the circumferential groove,
• the overlay layer being disposed under the circumferential groove and having an axial width between 70% and 200% of an axial width of the circumferential groove,
• the overlay layer being a reinforced ply layer or a layer comprising a fabric.
