<p>A pneumatic radial tyre (1) comprises a carcass ply (6A) wound around the axis of the tyre over one turn so that the terminal edge (E2) of the winding of the carcass ply (6A) overlaps with the starting edge (E1) thereof to define an overlap-joint (11), the overlap-joint (11) being provided in one of the starting edge (E1) and terminal edge (E2) with at least one cut (12) by which carcass cords existing therein are cut, and a method of making the same comprises the steps of cutting the starting edge (E1) prior to winding a carcass strip or cutting the terminal edge (E2) prior to the end of winding a carcass strip, whereby a joint-dent in the finished tyre is decreased and tyre uniformity, appearance, durability and the like are be improved. <IMAGE></p> |
