Abstract

The present invention relates to a tire (1) comprising: - a tire carcass (2) on which a tread (3) with two opposite shoulders (4, 5) is arranged; - from each shoulder (4 or 5), a flank (6 or 7) extends, ending in a bead (8 or 9) adapted to cooperate with an external bead surface (10 or 11) thereof with an edge (12 or 13) of a channel (14) of a rim (15) of a wheel (100) of a vehicle; - said tread (3) and said flanks (6, 7) embrace a main chamber (16) on three sides; - each of said flanks (6 or 7) comprises an internal flank surface (17); - said tire (1) further comprises at least one bead seat wall (19) which is connected to two attachment portions (20, 21), separate from each other, of the internal surface (17) of at least one of said flanks (6 or 7), forming a bead seat chamber (22) with said at least one flank (6 or 7); - wherein one of said attachment portions (20) is placed close to the bead (10 or 11) at which said at least one flank (6 or 7) ends; and wherein - said bead (10 or 11) placed close to said attachment portion (20) comprises a bead projection (23); - said bead projection (23) protrudes from the opposite side of said external bead surface (8 or 9) into said main chamber (16); - said bead projection (23) forms a bead resting surface (24) which is connected to said at least one flank (6 or 7) and faces said bead seat wall (19) so that when said tire (1) is statically and/or dynamically stressed by the rolling of the wheel (100) of a vehicle, it allows the support of said bead seat wall (19) on said bead resting surface (24).
