a method for reducing tire microsliding includes defining a rotation point and rotating a cross section profile about it . a cross section of a radially - external reference profile of a tread band includes a first rectilinear segment near at least one circumferential rib of a first shoulder portion . the first rectilinear segment extends axially outward beyond a corresponding shoulder edge point . a cross section profile of the at least one circumferential rib of the first shoulder portion includes a second rectilinear segment . the rotation point is on the first rectilinear segment , either the corresponding shoulder edge point itself or axially outward of it . the cross section profile of the first rectilinear segment is rotated to define the cross section profile of the second rectilinear segment , so that an axially - inner end of the second rectilinear segment is closer to the carcass structure than an axially - inner end of the first rectilinear segment .
