A multipurpose tyre for a motor vehicle is provided with a tread (2; 52; 62; 162; 262; 362) which has a central region (3) comprising at least first and second blocks (22, 23; 66, 67) arranged between an equatorial plane (100) and a circumferential groove (14); the first and second blocks (22, 23; 66, 67) form a first and a second row (11, 12) and are separated from each other by first and second grooves (30, 31; 73, 74) which extend in an oblique direction relative to the equatorial plane (100); the first oblique grooves (30; 73) extend substantially perpendicularly relative to the second oblique grooves (31; 74); and each first oblique groove (30; 73) crosses two successive second oblique grooves (31; 74) and forms with each of them a respective junction which is essentially T-shaped (32, 33; 94, 95). |
