Studded tyre comprising a tread band which extends between a first lateral edge and a second lateral edge, which are axially opposite each other, an equatorial plane extending through said tread band, respective pluralities of grooves and blocks which collectively define a tread pattern of said tyre being formed on said tread band, wherein: - there is identified in said tread pattern at least one module which extends between opposite axial ends of said tread band and which is the minimum portion of tread band the configuration of which is repeated in succession over the entire circumferential extent of said tread band to form said tread pattern, - each module comprises a first and a second elementary portion (R, S) of said tread band, which extend between said axial ends of the tread band and are arranged in the same succession within each module, each of said first and second elementary portions extending independently in a circumferential direction by an extent which corresponds to a long pitch or by an extent which corresponds to a short pitch, which is less than said long pitch, - each module is divided by said equatorial plane into a first region, which extends from said equatorial plane up to said first lateral edge, and a second region, which extends from said equatorial plane up to said second lateral edge, - there are identified among said modules a plurality of first modules (M') which comprise at least 40% of the total of said modules, the number of studs provided in said first region of said first module (M') being equal to the number of studs provided in said second region of said first module (M'), - said studs are arranged in said first modules so as to be mutually misaligned with respect to an axial direction, perpendicular to said equatorial plane, - there is defined between the studs of said first region a first ranking of distance of the studs from said equatorial plane, - there is defined between the studs of said second region a second ranking of distance of the studs from said equatorial plane, - there are defined pairs of homologous studs which are formed by a stud (101a, 102a, 103a) of said first region and by a stud (101b, 102b, 103b) of said second region having the same position in said first ranking and, respectively, in said second ranking, - at least 20% of said first modules (M') comprise at least one pair of homologous studs in which one stud is provided on said first elementary portion and the other stud is provided on said second elementary portion. - there is identified in said tread pattern at least one module which extends between opposite axial ends of said tread band and which is the minimum portion of tread band the configuration of which is repeated in succession over the entire circumferential extent of said tread band to form said tread pattern, - each module comprises a first and a second elementary portion (R, S) of said tread band, which extend between said axial ends of the tread band and are arranged in the same succession within each module, each of said first and second elementary portions extending independently in a circumferential direction by an extent which corresponds to a long pitch or by an extent which corresponds to a short pitch, which is less than said long pitch, - each module is divided by said equatorial plane into a first region, which extends from said equatorial plane up to said first lateral edge, and a second region, which extends from said equatorial plane up to said second lateral edge, - there are identified among said modules a plurality of first modules (M') which comprise at least 40% of the total of said modules, the number of studs provided in said first region of said first module (M') being equal to the number of studs provided in said second region of said first module (M'), - said studs are arranged in said first modules so as to be mutually misaligned with respect to an axial direction, perpendicular to said equatorial plane, - there is defined between the studs of said first region a first ranking of distance of the studs from said equatorial plane, - there is defined between the studs of said second region a second ranking of distance of the studs from said equatorial plane, - there are defined pairs of homologous studs which are formed by a stud (101a, 102a, 103a) of said first region and by a stud (101b, 102b, 103b) of said second region having the same position in said first ranking and, respectively, in said second ranking, - at least 20% of said first modules (M') comprise at least one pair of homologous studs in which one stud is provided on said first elementary portion and the other stud is provided on said second elementary portion.
