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-balancing including a tire-balancing material in a first pocket of the system and at least one tire accessory such as a tire-valve core in the second pocket of the system. The first and second pockets are spatially separated from one another with a seal and a line of perforation. The first pocket has a duct dimensioned to release the particles, oriented towards the second container, and sealed from the second container. The methods for fabrication of the tire-balancing system and balancing a tire with the use of such system. Before use, the first pocket is opened by separating the second pocket along the perforation, and placed in a tire let a flow of the particles from inside the first container into the tire through the duct. The tire-valve core is removed from the second container and applied to the wheel.

The present technology provides a pneumatic tire provided with a mechanical fastener member for attaching an object to the inner surface of a pneumatic tire, wherein the mechanical fastener member is bonded with high bonding strength to the inner circumferential surface of the tire, and a method of manufacturing the same. The pneumatic tire of the present technology comprises a mechanical fastener member on a tire inner surface, the mechanical fastener member corresponding to a first member of a mechanical fastener separable into two members and being fixed protruding to a tire cavity side. A fixing strength of the mechanical fastener member is from 0.1 to 100 (N/mm.sup.2).

The present technology provides a pneumatic tire having a mechanical fastener member for attaching an object with specific functionality to an inner surface of the pneumatic tire, particularly, a pneumatic tire such that, as the pneumatic tire rolls, the object with the specific function attached by the mechanical fastener member can be effectively prevented from executing rotating motion about the mechanical fastener member as a rotation central axis. The pneumatic tire of the present technology has a first member of a mechanical fastener separable into two members, disposed on the tire inner surface. On the tire inner surface around the mechanical fastener member, a recessed flat surface region is formed as a recessed portion having a step from peripheral portions of the recessed portion.

A tire pressure detector disposed at a wheel, wherein the wheel includes a rim and a tire mounted around the rim, with a pressure space formed between the tire and the rim. The rim includes an air tap connected with the pressure space. The tire pressure detector includes a main body movably disposed in the pressure space and provided with a housing space, and a detection module disposed in the housing space. The detection module further includes a sensing unit for sensing the air pressure in the pressure space and producing a pressure signal. A central processing unit of the detection module receives the pressure signal and wirelessly transmits the pressure signal through the wireless transmission unit. Therefore, vibration and waving issue due to imbalance weight is avoided, thus balancing the wheel.

A system for monitoring parameters of a vehicle wheel assembly includes a wheel speed sensor configured to produce a wheel speed signal, and a wheel assembly monitoring module operatively connected to the wheel speed sensor. The wheel assembly monitoring module determines a dynamic response of the wheel speed signal at one or more wheel speeds. A wheel assembly health module provides one of a visual output, an audible output, and a haptic output indicating that the wheel assembly has exceeded a selected wheel assembly parameter threshold based on the dynamic response of the wheel speed signal.
