A tire may include a tread portion, first and second sidewall portions extending radially inward from the tread portion. an inner surface defining an inner cavity of the tire between the first and second sidewall portions, and a spiral wound sealant bead laid down on the inner surface, the sealant bead having a starting end portion closest to the first sidewall and a terminating end portion closest to the second sidewall, the starting end portion and the terminating end portion overlapping by an overlap angle about a tire axis in a range of from 80 to 100 degrees.

The present disclosure is directed to methods and systems for optimizing the performance of bicycle-type wheels and wheel components. One example includes the manufacture, arrangement, and assembly of rims, tires, tubes and/or other components in a manner that results in an optimal smooth rotation with little or close to no oscillation and/or yaw by controlling, marking, and aligning the heavy spots inherently created during the production of such components. Other aspects of the present disclosure are directed to methods and systems for monitoring and alerting a user to imbalance of a wheel system, a rotational weight shifting wheel, and a valve-less tire.

The invention relates to a pneumatic vehicle tire of a radial construction having a gas-tight inner layer, wherein on the side of the gas-tight inner layer that in the vulcanized and mounted pneumatic vehicle tire is directed towards the wheel rim there is at least one patch containing one or more liquid rubbers and one or more solid rubbers.

The subject invention relates to a method of preparing a tire inner surface to attain better adhesion of balance pads, puncture sealants, and noise reduction foams. In this method a strip of multi-axially stretchable film is adhered to the inner surface of an uncured tire with a pressure-sensitive adhesive. Then a release agent coating is applied to the film strip on the inner surface of the uncured tire which is subsequently cured in a suitable mold at an elevated temperature. The cured tire is then removed from the mold and after allowing the cured tire to cool the annular circumferential film strip is removed from the inner surface of the tire to provide a circumferential release coating-free tire inner surface onto which balance pads, puncture sealants, and noise reduction foams can be adhered.

The invention relates to tire balancing compositions having improved balancing properties comprise a visco-plastic gel and solid bodies having an average smallest dimension in the range of 0.5-5 mm; preferably 1-4 mm, more preferably around 3 mm. When applied in a layer to the inside of a motor vehicle tire, the compositions act by allowing the solid bodies move through the gel and to concentrate in areas to counteract imbalances. The solid bodies preferably have an average ratio between their smallest and their largest dimension of 2, more preferably 1.5, especially around 1. The visco-plastic gel preferably has a storage modulus (G) between 1000 Pa and 25000 Pa at 22 C., a loss modulus (G) smaller than the storage modulus, and a critical yield stress above 3 Pa at 22 C. The bodies may be shaped as prolate or oblate ellipsoids, cylinders, rectangular paralleipipeds, or spheres, or mixtures of such bodies; they may have an apparent specific gravity in the range of 500-3000 kg/m.sup.3, preferably 600-2000 kg/m.sup.3, in particular 700-1000 kg/m.sup.3, especially 800-900 kg/m.sup.3; they may be made from polyolefins, polystyrene, polyvinyl chloride, polyamide, rubber or glass. The weight ratio between the solid bodies and the gel is from 10:1 to 1:10, preferably from 5:1 to 1:5, in particular from 2:1 to 3:1, such as from 1:1 to 1:2. The invention further concerns a tire balancing kit and a method for balancing automobile wheel assemblies.

A set of tire balancing beads including a set of solid non-absorbent beads; and a set of super moisture absorbent beads.

An aircraft tire has a pair of bead sections, sidewall sections extending from outer side in a radial direction of 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 an information about the aircraft tire and an antenna extended from the tag main body, wherein, when a diameter size of the aircraft tire is 15 inches or less, in a tread surface view, the antenna is disposed such that the antenna is parallel to a tire circumferential direction or intersects the tire circumferential direction within a predetermined angle range, and a belt part disposed in the tread section is made of non-metal material.

An iron hooked balance weight includes a balance weight body and a hook. A hook positioning cavity is machined in a center of a back surface of the balance weight body, and two first riveting holes are machined in the hook positioning cavity. The hook includes a riveting part and a hook body part. The hook body part is provided with a cambered window, and an anti-dropping barb is arranged in the cambered window. Two second riveting holes are formed in the riveting part, and the hook and the balance weight body are riveted through a riveting member. The hook body part fits with a top surface of the balance weight body to form a hooking cavity, and a hooking introduction port of the hooking cavity is formed between a front end of the hook body part and a front end surface of the balance weight body.

A pneumatic tire includes a sound absorbing member having a band shape. The sound absorbing member is bonded to an inner surface of a tread portion along a tire circumferential direction. The sound absorbing member includes a missing portion at at least one location in the tire circumferential direction. The at least one missing portion is disposed in a range corresponding to a light point in a tire main body. A correction body for correcting weight unbalance is fixed to a tire inner surface in the missing portion within the range corresponding to the light point.
