    摘要： A pneumatic tyre (1) comprising a tread (2) having a plurality of main grooves (3) extending continually in the circumferential direction and a plurality of lateral grooves (4) crossing between the adjoining main grooves (3) and having a groove depth DB of 0.6 to 0.95 times the mean DM of groove depths DA1, DA2 of the adjoining main grooves (3), characterised in that said plurality of lateral grooves (4) are composed of, in a section orthogonal to the groove centre line, an upper portion (6) having an opening at the tread surface (2A), a lower portion (9) having a groove bottom and a constricted waist portion (7) consecutive to the upper and lower portions (6,9) and having the narrowest width WS of each lateral groove, and the following relation is established: 1.0mm ≦ WS ≦ 4.0mm 1.3 ≦ WW/WS ≦ 3.0 0.15 ≦ DS/DB ≦ 0.7
    where:
       WS is the narrowest width,
       WW is the widest width of the lower portion,
       DS is the length of the waist portion in the tyre radial direction.
