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