摘要： A method of manufacturing an agricultural tyre (1) with deep cross-lugs (6), comprising the steps of: (a) proving a tyre case (2) and tread belts (3); (b) applying rubber blocks (206) onto tread belts (3), each of such rubber blocks (206) being arranged to make a respective lug (6) of the final tread (4); (c) winding a rubber ribbon (200) above said rubber blocks (206) so as to completely enclose said rubber blocks (206); (d) curing the rubber blocks (206) together with the wound ribbon (200) in a curing mould (105) negatively reproducing a desired pattern of the tread (4).
