A method of manufacturing a tyre, the tyre comprising a tread portion (20, 30) comprising a rubber polymer and a carcass (10) comprising a polyurethane polymer, wherein the tread portion (20, 30) is directly bonded to the carcass (10), comprises the steps of: A) providing: A1) a vulcanized tread portion with an outward facing surface and an inward facing surface, the tread portion furthermore comprising a compound with hydroxyl groups, amino groups, isocyanate groups and/or carboxylic acid anhydride groups; or A2) an at most partially vulcanized tread portion precursor with an outward facing surface and an inward facing surface, the tread portion precursor furthermore comprising a compound with hydroxyl groups, amino groups, isocyanate groups and/or carboxylic acid anhydride groups; B) contacting the inward facing surface of the vulcanized tread portion of step A1) or the inward facing surface of the at most partially vulcanized tread portion precursor of step A2) with a polyurethane reaction mixture comprising a polyol, a polyisocyanate and a catalyst; C) curing the polyurethane reaction mixture of step B), thereby forming the carcass of the tyre.
