    摘要: The invention seeks to increase the resistance to unseating of a tyre operating at low pressure. This objective is achieved by a tyre comprising at least one bead, having an axial width D at the seat, comprising at least one main circumferential reinforcing element (22), of which the radially innermost point (222) is at a radial distance Z and at an axial distance Y from the radially innermost point (211) of the bead, and such that Y/D is at least equal to 0.5 and Z/D is at most equal to 0.4. This same bead comprises at least one bead layer (23), surrounding the filler rubber (21) and such that its axially outermost end (231) is radially on the outside of the end (311) of the carcass layer (31) and it also comprises at least one additional circumferential reinforcing element (24), radially on the inside of the radially outermost point (223) of the main circumferential reinforcing element (22).

    摘要: Fahrzeugluftreifen für einen PKW, Van oder Light Truck mit einer Radialkarkasse (3, 3a, 14) und mit zwei Wulstbereichen (11), welche wenigstens je einen Wulstkern (4), einen dem Wulstkern (4) aufsitzenden Wulstkernreiter (5) und einen den Wulstbereich (11) nach axial außen begrenzenden Wulststreifen (13) aufweisen, wobei die Radialkarkasse (3, 14) von axial innen nach axial außen um die Wulstkerne (4) geführt ist und in einem Karkasshochschlag (3a) endet und wobei die im Wulstbereich (11) angeordneten Bauteile Wulstkernreiter (5), Radialkarkasse (3, 3a, 14) und Wulststreifen (13) bestimmte Shore A-Härten aufweisen. Zur Verbesserung der Haltbarkeit des Wulstbereiches weicht die Shore A-Härte von axial unmittelbar benachbart im Wulstbereich (11) angeordneten Bauteilen (3, 3a, 14, 12, 13, 14, 15) nicht mehr als 5 Shore A-Härtepunkte voneinander ab.

    摘要: A pneumatic tire is disclosed herein. The pneumatic tire includes a carcass composed of one or more carcass plies that extend to span a tread, sidewalls, and bead parts. Ring bead sheet cords having a predetermined longitudinal length are disposed on both sides of each end of the carcass. Each bead part-side end of the carcass is interposed between the ring bead sheet cords. The ring bead sheet cords are each formed in a closed ring shape having no disconnection along a circumferential direction of the tire. Spaces between the ring bead sheet cords and between the carcass and ring bead sheet cords are filled with a rubber mixture.

    摘要: A pneumatic tire to reduce separation of a carcass ply from inner and outer core pieces (5i , 5o) and improve steering stability. A radially inner end portion of the carcass ply is held between the inner and outer core pieces (5i, 5o) without turning-up around a bead core. The inner and outer core pieces (5i , 5o) are made of helical body of bead cord (10i, 10o) helically winding around a tire axis. In the inner core piece (5i), the final twisting direction of the bead cord (10i) is the same as the winding direction around the tire axis of the bead cord (10i) in side view from axial outward of the tire. In the outer core piece (5o), the fi nal twisting di recti on of the bead cord (10o) is opposite to the wi ndi ng direction of the bead cord (10o).
