| 摘要 |
The present invention relates to a method for reducing the phenomena of tyre/ground microsliding local to a shoulder portion of a tyre. The tread band (1) of the tyre is provided with a raised pattern comprising a plurality of circumferential ribs (2, 4, 6) delimited by a corresponding plurality of circumferential grooves (3, 5), and has on its cross section a radially external reference profile (7, 8, 20) comprising a first rectilinear segment (20), local to at least one circumferential rib (2) of the said shoulder portion, which extends axially outwards beyond the edge (A) of the said shoulder portion. This method consists in assigning the said at least one circumferential rib (2) of the said shoulder portion a cross section profile composed of a second rectilinear segment (9) rotated radially lowereds about a point lying on the said first rectilinear segment (20) in a position axially not internal to the said edge (A) of the said shoulder portion. |
