A snow sock is provided that includes a covering that extends in a circumferential direction. The covering has a thickness and an outer surface. A first thickness section is present and extends along a first arc length, and has a first thickness section inner surface that engages the outer surface of the covering. At least 50% of the first thickness section inner surface engages the outer surface of the covering and/or a first fill element. A second thickness section is also provided and is spaced from the first thickness section. The second thickness section extends in the circumferential direction along a second arc length, and has a second thickness section inner surface that engages the outer surface of the covering. At least 50% of the second thickness section inner surface engages the outer surface of the covering and/or a second fill element.

A mold for vulcanizing a tire tread comprising a molding surface able to mold a tread surface of the tread of the tire and at least one bar of length L and of width W able to mold a groove in the tread. The bar comprises two lateral faces extending along the length of the bar and projecting from the molding surface and an upper face connecting the said lateral faces. The mold comprises in the bar at least two cavities respectively opening onto the two lateral faces of the bar without opening onto the upper face of this bar. These cavities overlap in the width of the bar. The mold further comprises a first element added into the bar beforehand, this first element separating the two cavities in the length of the bar.
