Abstract: A pneumatic tire includes at least three circumferential main grooves extending in the tire circumferential direction, and a plurality of land portions partitioned by the circumferential main grooves. The belt layer is formed by laminating a pair of cross belts having a belt angle, as an absolute value, of not less than 10° and not more than 45° and mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° with respect to a tire circumferential direction. Also, when viewed as a cross-section from the tire meridian direction, when the wear end surface of the circumferential main grooves is drawn, the distance Dcc on the tire equatorial plane from the circumferential reinforcing layer to the wear end surface and the distance De from the end portion of the circumferential reinforcing layer to the wear end surface have a relationship such that De/Dcc≦0.94.

Abstract: A pair of annular inserts of elastomeric material is circumferentially applied by spiraling around a laying surface of an auxiliary drum. Then a plurality of strip-like elements disposed in parallel side by side relationship with each other in the circumferential extension of the laying surface is applied onto the auxiliary drum, so as to form at least one first belt layer. Respectively opposite end portions of each strip-like element are radially superposed, each against one of the annular inserts, so that each of the annular inserts projects from a respective end edge of the strip-like element. The cap structure formed on the auxiliary drum is coupled to a carcass structure through toroidal conformation of the latter, in such a manner that the radially external ends of sidewall portions previously manufactured on the carcass plies are associated with the axially external ends of the annular inserts.
