<p>The invention concerns a tread pattern of the directional type for automobile tires that are intended for highpowered vehicles and for exacting conditions of usage caused by the great acceleration used and the very high speeds reached during such driving, even when cornering. The tread pattern comprises a plurality of small blocks having a substantially rhomboidal form disposed in at least six axially spaced and circumferentially extending rows, which are separated from each other by straight circumferentially extending grooves and by oblique transversal grooves. The grooves of the two axially centered rows are disposed astride the equatorial plane of the tire and are inclined in the contrary sense in each row, both with respect to the next row and with respect to the oblique grooves of the other remaining rows disposed in the same midplane as the tread band.</p> |
