    Abstract: To provide an aircraft tire capable of suppressing rubber tire wear during landing and shocks which accelerate or decelerate an aircraft at touchdown. An aircraft tire 3 includes, on a side of a tire body 4 constituting an outer peripheral part of an aircraft wheel 1, a protrusion 5 for receiving flight wind pressure. The wheel 1 is rotated ahead of the touchdown by the action of the wind pressure received by the protrusion 5 in a direction in which the wheel 1 rotates during a landing roll. Weight 15 is inserted into a hollow part 11 of the protrusion 5. Through use of centrifugal force on the weight 15 in association with a rotational motion of the wheel 1, the protrusion 5 is deformed to change its wind pressure receiving area for bringing rotational speed of the wheel 1 ahead of the touchdown close to a rotating speed of the wheel that is consistent with a flying speed of the aircraft making the touchdown.

    Abstract: An air maintenance tire (12) is disclosed comprising a tire cavity (28) bounded by first and second sidewalls (18) extending to a tire tread region (26); air pumping means (14) for generating pressurized air for maintaining air pressure within the tire cavity (28) at a preset pressure level, the air pumping means comprising a soft or elastic tubing (30, 80, 101, 102) and one or more compression fittings (320); and a valve housing (110) disposed adjacent an outward end of a valve stem (80), wherein the valve housing is operative to selectively open and close pressurized air flow from an internal passageway of the valve stem (80) into the tire cavity (28), the valve housing (110) being connected to the air pumping means (14) by the soft or elastic tubing (30, 80, 101, 102) and the compression fittings (320) for mitigating a dynamic loading on the compression fittings (320). The first sidewall (18) comprises at least one bending region operatively bending within a rolling tire footprint and a sidewall groove or passageway (32) positioned within the bending region of the first tire sidewall (18), the sidewall groove or passageway (32) deforming segment by segment between a non-deformed state and a deformed, constricted state in response to the bending of the first sidewall (18) bending region within the rolling tire footprint.

    Abstract: A tire (10) for a construction vehicle, provided with a pair of bead cores (12) constituting a bead portion (22), and a carcass (14) extends between the bead cores (12) and having a folded ply (14p) folded back at the bead cores (12). The bead portion (22) is provided with a plurality of recessed portions (28) arranged at intervals around the tire circumferential direction so as to be recessed from the outside of the tire towards the folded ply (14p). When SH represents the tire section height, H1 represents the height from the rim radius (R) to the tire-radial-direction inside edge of the recessed portions (28), and H2 represents the height from the rim radius (R) to the tire-radial-direction outside edge of the recess parts, the relationships H1/SH > 0.04 and H2/SH

    Abstract: In a pneumatic tire 2 according to the present invention, in the vicinity of a bead 10 portion, a main portion 42 of a carcass ply 40 is passed through the vicinity of a neutral surface. A tensile force and a compressive force applied to the main portion 42 are small. In the tire 2, occurrence of pinch cut is suppressed. In addition, this structure alleviates a force applied to the main portion 42 even during run-flat running. In the tire 2, damage is less likely to occur even during run-flat running for a long period of time. The tire 2 has excellent run-flat durability. Furthermore, in the tire 2, an increase in the vertical stiffness constant or weight thereof is suppressed.
