Abstract
A tire includes a carcass, a tread band having a radially outer tread surface and a plurality of radially extending recesses, and an anti-slip structure disposed in one of the radially extending recesses. The anti-slip structure includes a first circular inner portion, a second outer portion, and a third core portion. The third core portion comprises an assembly of three pin structures for providing traction over ice. Each pin structure has a wedge-shaped base portion secured within the first circular inner portion and a pin extending through the second outer portion to the tread surface. The three wedge-shaped base portions combine to form a circular base portion for the assembly.
