Low-noise tire and method for manufacturing same

A tire (10) comprising a crown (12), two sidewalls (22), two beads (24), each sidewall (22) connecting each bead (24) to the crown (12), and a carcass reinforcement (32) anchored in each bead (24) and extending in each sidewall (22) and radially inwardly at the crown (12), the crown (12) comprising:

• a tread (20) intended to come into contact with a ground when the tire (10) is rolling;
• and
• a crown reinforcement (14) arranged radially between the tread (20) and the carcass reinforcement (32), the carcass reinforcement (32) comprising at least one carcass layer (34), the crown reinforcement (14) comprising a working reinforcement (16) comprising at least one working layer (18),
• wherein the tire further comprises a sealing layer (15) for sealing against an inflation gas, the sealing layer (15) being intended to delimit an internal cavity closed with a mounting support for the tire (10) once the tire has been mounted on the mounting support, the sealing layer (10) comprising a junction (21) between two circumferential end edges (23A, 23B) of the sealing layer (15), the junction (21) forming a radial overlap between one of the circumferential end edges (23A, 23B) of the sealing layer (15) and the other of the circumferential end edges (23A, 23B) of the sealing layer (15), the junction (21) extending in a main direction (D4) forming, with the circumferential direction (Z) of the tire:
• in a portion (15S) of the sealing layer (15) extending axially in radial line with the working layer (18) or a radially innermost working layer (18) and having an axial width equal to at least 40% of an axial width of the working layer (18) or of the radially innermost working layer (18), an angle (ES) ranging, in absolute value, from 20° to 60°, and
• in a portion (15F) of the sealing layer (15) extending radially in each sidewall (22) and having a radial height equal to at least 5% of a radial height (H) of the tire (10), an angle (EF), in absolute value, strictly greater than the angle (ES) of the main direction (D4) of the junction (21) in the portion (15S) of the sealing layer (15) extending axially in radial line with the working layer (18) or the radially innermost working layer (18).
