Abstract: A car tyre having a tread that extends in axial direction for a width the tread including a central portion arranged across an equatorial plane, and two lateral portions opposed with respect to the central portion. The central portion is separated from the lateral portions of the tread by two circumferential grooves. The circumferential grooves have a width greater than about 6 mm. The central portion extends in axial direction for a width less than 20% of the width of the tread and includes a plurality of first sipes. Each lateral portion has a width greater than 30% of the width of the tread, and each lateral portion includes, furthermore, a plurality of transversal grooves. The transversal grooves of a lateral portion include at least a first inclined length that extends from a zone proximal to the respective circumferential grooves, moving away from the equatorial plane. The first inclined length has an inclination ??60° with respect to equatorial plane. Each lateral portion includes a plurality of sipes.

Abstract: A tyre includes a carcass structure including at least one carcass ply, a belt structure applied in a radially outer position with respect to the carcass structure, and a tread band applied in a radially outer position with respect to the belt structure. The belt structure includes two main belt layers and first and second reinforcing strips incorporating a plurality of reinforcing elements arranged substantially in the circumferential direction. The reinforcing elements include at least one high-elongation metal cord including a plurality of intertwined strands, and each strand includes a plurality of filaments. Each filament has a diameter not greater than 0.175 mm.
