摘要： There is disclosed tyres for motor vehicles each having a tread (10) provided with a plurality of large convex portions (1) and small convex portions (2), the large convex portions (1) and the small convex portions (2) being differentiated in heights and areas thereof, the small convex portions (2) being disposed around the large convex portion (1) for forming a plurality of normal pyramidal structures. The normal pyramidal structures are formed by disposing the large concave portion (3) around the small concave portion (4). There is formed a reversed pyramidal structure by disposing the large convex portions (1) around the small convex portion (2).
