  • Patent number: 9440500
    Abstract: A pneumatic tire in which a cavity resonance sound is reduced while punctures are easily repaired with a puncture sealant. The pneumatic tire has a fibrous region where short fibers are bonded onto an inner surface of the tire. A circumferential fiberless region where short fibers are not bonded onto the inner surface of the tire extends circumferentially between both ends of a tread ground contact area.

  • Publication number: 20150224534
    Abstract: The present invention provides a fiber coating device for tires, for coating an inner surface of a tire with fibers, comprising: a tire support means for supporting a tire; a fiber supply means including a fiber jetting outlet and adapted to spray fibers from the fiber jetting outlet onto an inner surface of the tire supported by the tire support means; and a fiber charging means for charging the fibers sprayed from the fiber jetting outlet, wherein the fiber jetting outlet of the fiber supply means and the fiber charging means are disposed in a space defined by the inner surfaces of the tire and a pair of imaginary disc-shaped faces of which circumferential peripheries correspond to inner circumferential peripheries of respective bead portions of the tire when the tire is supported by the tire support means.

  • Publication number: 20140166179
    Abstract: A pneumatic tire with short fibers fixed to the inner surface of the tire with improved peel resistance, and a method of producing such a pneumatic tire. The pneumatic tire has a carcass toroidally extending from a tread portion along a pair of sidewall portions to a pair of bead portions, and bead fillers provided radially outwardly of bead cores embedded in the bead portions, including flocking areas in which many short fibers are fixed to at least part of an inner surface of the pneumatic tire with an adhesive. The flocking areas are positioned such that their tire radial direction inner ends are positioned inwardly in the tire radial direction as compared to the tire radial direction outer ends of the bead fillers and are spaced a given distance outward in the tire radial direction apart from bead toes.

  • Patent number: 8028796
    Abstract: The present invention provides an assembly of a tire and a rim, which assembly has on the tire inner cavity side thereof a sound absorbing member capable of effectively suppressing cavity resonance and reducing road noise, while suppressing increase in weight of the tire and increase in volume of the sound absorbing member. In this assembly of a tire and a rim, the sound absorbing member is mounted on the inner cavity side of the tire as a sound absorbing layer for suppressing cavity resonance inside the tire. The sound absorbing member is unwoven cloth made of plural fibers, and the average distance d between fibers constituting the unwoven cloth is within the range of 0.50? to 4.00?.

  • Publication number: 20090308519
    Abstract: An improved pneumatic tire with a porous layer that is fixedly attached to a tire inner surface with improved fixation strength, suitable for effectively reducing a cavity resonance noise generated within a space defined by the tire and rim. To realize such a pneumatic tire, according to the invention, the porous layer (9) is fixedly attached to the tire inner surface through an impregnated layer (10), which is impregnated in the porous layer over part of the thickness of the porous layer.
