Abstract: A winter tire with improved traction on snow surfaces; the tire has a tread with a raised pattern defined by a number of longitudinal and transverse grooves which form at least one longitudinal row of blocks projecting radially from a base surface of the tread. Each block has two longitudinal lateral surfaces bounding two corresponding longitudinal grooves, and two transverse lateral surfaces bounding two corresponding transverse grooves. At least one of the blocks has lateral channels, each of which is formed on the lateral surface of a corresponding block, extends from the base surface of the tread to a top surface of the block, and is designed to impede radial spin-out of snow trapped inside the lateral channel.

Abstract: An antistatic tire having a tread made from a first mix (MP1) and having two annular shoulders and a peripheral rolling surface, two opposite annular portions of the rolling surface being defined by outer annular surfaces of the shoulders. Each shoulder is made from a second mix (MPC), which is electrically conducting, and which, under low strain, has substantially the same rigidity as the first mix (MP1), and, under high strain, has a greater rigidity than the first mix (MP1). In a second embodiment, an electrically conducting element is inserted inside the tread. The conducting element and the shoulders both being made of an electrically conducting third mix, which, under low strain and in the cured state, has the same mechanical characteristics as the first mix in the cured state, and, under high strain, has the same mechanical characteristics as the second mix in the cured state.
