Abstract
A method of making a tire includes making a carcass structure; applying a belt structure, tread band, and at least one pair of sidewalls; and vulcanizing the tire. Making the carcass structure involves formation of at least one first carcass ply, including preparing and depositing at least one continuous strip element onto a toroidal support in alternating deposition sections. Each deposition section extends in a substantially U-shaped conformation against a profile in transverse section of the toroidal support or a previously deposited deposition section, substantially over an entire length of the section, to define two side portions, a crown portion, and two transition regions defined between the side and crown portions. The crown portions of the deposition sections are arranged consecutively in side-by-side relationship along a circumferential extension of the toroidal support. Edges of circumferentially consecutive deposition sections abut evenly along their entire crown portions extending between the transition regions.
