Method for making a tire for vehicle wheels |
摘要 |
A vehicle tire is made by inflating a vulcanized air tube to a slight pressure. Then, at least one thread element is wound around the transverse profile of the air tube to form a first carcass ply consisting of turns disposed consecutively in side-by-side relationship. A pair of annular anchoring elements is applied to the first carcass ply. Then, a second carcass ply is formed by winding at least one thread element so as to form turns disposed consecutively in side-by-side relationship along the circumferential extension of the air tube. Associated with the carcass structure is an annular element made up of a belt structure and a tread band. The carcass structure and annular element can be vulcanized separately from each other to make a tire having a tread band susceptible of replacement together with the belt structure.
