More Information
Summary:A car tyre (100), in particular a high or ultra high performance car tyre also suitable for use on track, is described; the tread band (1) of the tyre has a central region (L1), separated from two shoulder regions (L2, L3), respectively an outer shoulder region (L2) and inner shoulder region (L3); the outer shoulder region (L2) has a width greater than the width of the inner shoulder region (L3); the outer and inner shoulder regions are provided with relatively large grooves (5,6); in the outer shoulder region these grooves (5) alternate with narrower grooves (7), which reduce the stiffness of this tyre region only to a limited extend; the central region (L1) of the tyre, instead, was designed so as to have a low void-to-rubber ratio of equal to or smaller than 0.09.
