A vehicle tyre having a unidirectional tread pattern, provided with two circumferential grooves (3) to divide the tread portion into two outer parts (5R,5L) and a central part (4) therebetween, the central part (4) is substantially continuous in the tyre circumferential direction and formed symmetrically about the tyre equator (CO), the outer parts (5R,5L) are provided with mirror-image patterns (PR,PL) , each formed by circumferentially repeating pattern units (7R1-7RN,7L1-7LN) having an average circumferential length (K), and the mirror-image patterns (PR,PL) are circumferentially shifted from each other by a distance S of from 0.15 to 0.25 times the above-mentioned average circumferential length (K). <IMAGE> |
