An aircraft tire has a pair of bead sections, sidewall sections extending from the bead sections, and a tread section extending between the sidewall sections; the aircraft tire includes an RFID tag having a tag main body (IC chip) configured to store information about the aircraft tire, and an antenna extended from the tag main body, wherein, in a tread surface view, the antenna is disposed such that an extending direction of the antenna is parallel to a tire width direction or intersects the tire width direction within a predetermined angle range, and the aircraft tire satisfies a configuration 0.1<L/W<0.2, where a width of the aircraft tire is denoted as “W” and a total length of the antenna in the extending direction of the antenna is denoted as “L”, and when a diameter of the aircraft tire is 21 inches or more.

A container system for particles of a tire-balancing material has a first container for holding the particles and a second container for holding at least one accessory such as a tire-valve core. The second container is connected to the first container and a perforation is provided between the first container and the second container. The first container has a duct dimensioned to release the particles, and oriented towards the second container. The duct is sealed by the second container as a result of connection between the first and second containers. Before use, the first container is opened by separating the second container along the perforation. The opened first container is placed in a tire, where the duct facilitates a smooth flow of the particles from inside the first container into the tire. The tire-valve core is removed from the second container and applied to the wheel.

A pneumatic tire (1) includes a mechanical fastener (3) formed of at least two or more fastener components (3a, 3b) and attached to a tire inner surface (2). In such a pneumatic tire (1), the two or more fastener components (3a, 3b) of the mechanical fastener (3) are fixed with a resin reinforcement member (7) sandwiched therebetween, the resin reinforcement member (7) including at least one layer of a resin film or resin sheet including any of: (a) a resin or a resin composition made of a blend of resin and an elastomer; (b) a resin or a resin composition made of a blend of a resin and an elastomer including arranged fibers; and (c) a resin or a resin composition made of a blend of a resin and an elastomer with short fibers compounded therein.

A balancer for a wheel and tire assembly includes one or more tubes 101 containing a movable mass 104. The tube or tubes is/are mounted to a resiliently deformable support 102 with an outer dimension that substantially matches an inner dimension of the tire. the support being arranged to position and support the or each tube within the tire. The/or each tube may be annular. The support may be formed from a plastics mesh 102.

A pneumatic tire comprises: a fastener disposed on a tire inner surface, the mechanical fastener being a first mechanical fastener of a separatable pair of mechanical fasteners composed of at least two fastener members; wherein a) the fastener members sandwich a rubber-coated fiber reinforced member and fix together; b) the fastener is disposed within a region such that the following relationship is satisfied: 0.05≦A/H≦0.4, where A is a height in a tire radial direction from a bead toe end to a center position (C) of the fastener, and H is a height of a cross section of the tire; and c) the fiber reinforced member includes fiber bundles disposed in alignment in at least one direction, and forms an angle (minor angle θ) with a tire circumferential direction such that: 30 degrees≦θ≦90 degrees.

Particular embodiments of the invention comprises a composition for reducing weight imbalances, force variations, and/or vibrations in a tire-wheel assembly, the composition comprising a first plurality of particulate for positioning within the tire-wheel assembly, where each particle in the first plurality of particulate is characterized as having low energy absorption capabilities, and a second plurality of particulate for positioning within the tire-wheel assembly, where each particle in the second plurality of particulate is characterized as having elevated energy absorption capabilities. Additional embodiments of the invention comprise a method for reducing force imbalances, force variations, and/or vibrations in a tire-wheel assembly, which includes the steps of providing a tire-wheel assembly and placing into a pressurization chamber of said tire-wheel assembly a composition as contemplated in any embodiment or combination of embodiments suggested herein.

A pneumatic tire includes at least one balance patch arranged on a tire inner surface that is a surface on the inner side of the tire, and a functional component having a communication function and arranged on the tire inner surface at a position separated at a predetermined angle θ from the balance patch in a tire circumferential direction.

A method of correcting imbalance of a tire comprises a step of forming a coated layer on the inner surface of the tire at the point of lightest weight of the tire so as to reduce the imbalance of the tire. The coated layer has a black color substantially the same as the color of the inner surface so that it becomes difficult to recognize the correction of the weight imbalance.

A tire testing method includes: applying a lubrication solution to a bead part of a tire; detecting a phase of a reference point of the tire; detecting a phase of a rotation origin of a spindle at common coordinates shared with coordinates at which the phase of the reference point is indicated; detecting a singular point present on the tire by conducting a tire test while rotating the tire on the spindle, and detecting a phase from the rotation origin to the singular point; calculating a phase from the reference point to the singular point based on the phase of the reference point, the phase of the rotation origin, and the phase from the rotation origin to the singular point; storing information about the reference point and information about the rotation origin at the common coordinates; and marking the tire at a position where the singular point is present.
