A tread for a tire includes a first circumferential main groove, a second circumferential main groove, and a third circumferential main groove. The first, second, and third circumferential main grooves together define a first shoulder rib, a first intermediate rib, a second intermediate rib, and a second shoulder rib. The third circumferential main groove includes a plurality of connecting bridges spaced circumferentially within the third circumferential main groove and axially joining the second intermediate rib and second shoulder rib.

Tire

Both a mold blade for forming sipes and the sipe so formed in a tire tread element have three-dimensional portions. In the formed sipe, the three-dimensional portion creates a constant interlocking of the opposing sipe faces. The blade and the sipe have two radially adjacent rows of projections, wherein the projections are separated by a planar section, the planar section having a defined length and width.
