Disclosed is a pneumatic tire including a film attached to an inner liner, and a plurality of porous sound absorbing members attached to the film and arranged at a predetermined interval. According to the pneumatic tire, occurrence of resonance noise in the tire may be reduced.

The method of this invention provides a simple and inexpensive method for manufacturing self-sealing pneumatic rubber tires of the tubeless type having a higher degree of uniformity than can be made utilizing conventional manufacturing procedures that are currently being practiced. In the practice of this invention a low viscosity sealant formulation, which would ordinarily be difficult to handle and build into an uncured tire, is encapsulated in a stiff rubber formulation. This makes it relatively easy to build the sealant layer into the tire since the low viscosity sealant formulation is contained with the more rigid solid material. The low viscosity sealant material requires little and preferably no depolymerization to act effectively as a sealant. Accordingly, it does not need to be depolymerized with a peroxide which causes off-gassing and the resultant tire uniformity and balance issues normally associated with polymer break down.

Vehicle pneumatic tyre comprising a sealant layer, and method for detecting a vehicle pneumatic tyre comprising a sealant layer and for recycling a vehicle pneumatic tyre comprising a sealant

There is provided silicone based materials with enhanced tackiness upon cure. These may be used for cured self-adhering silicone-based products such as pressure sensitive adhesives, self-adhering materials and/or self-sealing materials, made from condensation curable silicone-based compositions, the compositions therefor and to applications for which said self-adhesive products may be used. In one particular application the cured silicone based material may be utilised as a self-sealing layer in an inflatable article such as a pneumatic tire.

A pneumatic tire is proposed. The pneumatic tire may include an inner liner configured to maintain a pressure of air filled inside the pneumatic tire, a sealant layer disposed on an inner peripheral surface of the inner liner, and a sound absorbing material disposed adjacent to the sealant layer. The sealant layer may include a first sealant layer formed by a first sealant string adjacent to at least a portion of an inner peripheral surface of the inner liner. The sealant layer may also include a second sealant layer formed by a second sealant string adjacent to at least a portion of the first sealant layer. The second sealant layer may be equal to or smaller, in width, than the first sealant layer in an axial direction of the pneumatic tire. The sound absorbing material may be smaller in width than the first sealant layer in the axial direction.

The present disclosure relates to a tire including a sealant layer and a sound-absorbing material layer, and the tire includes a sound-absorbing material layer which is adhered to an inner surface of the tire and a sealant layer which is disposed between the inner surface of the tire and the sound-absorbing material layer and includes a sealant for adhering the sound-absorbing material layer to the inner surface of the tire. The tire has noise reduction performance while enabling a self-sealing operation to be carried out when a tire puncture occurs by adhering a sound-absorbing material layer to a sealant layer applied to an inner surface of the tire, improves flowability of the sealant by increasing average pore size of a sound-absorbing material, thereby reducing specific surface area between the sealant and the sound-absorbing material, and prevents fine pieces of the sound-absorbing material from deteriorating function of the sealant and can also maintain noise reduction performance by decreasing adhesion specific surface area between the surface of the nail and the sound-absorbing material even when a nail reaches the sound-absorbing material by penetrating the tire and the sealant.

The present invention provides a pneumatic tire including a sealant layer that has excellent tear resistance despite its being formed of a generally string-shaped sealant provided continuously and spirally along an inner periphery of the tire. Included is a pneumatic tire including an innerliner and a sealant layer located radially inside the innerliner, the sealant layer including a first sealant layer and a second sealant layer stacked in that order from the innerliner, the first sealant layer including a generally string-shaped sealant provided continuously and spirally along an inner periphery of the tire, the second sealant layer including a generally string-shaped sealant provided continuously and spirally along the first sealant layer, the sealant of the first sealant layer and the sealant of the second sealant layer extending in directions crossing each other.

Methods for treating the surface of a cured inner liner are disclosed. By use of these methods a treated, cured inner liner is produced which has a lower surface with increased adherability to other materials (e.g., adhesives). Treated, cured inner liners resulting from such methods as well as tires containing the treated inner liners.

Tire with sidewalls (6) having, on their outer surfaces, a set of protuberances (8) that alternate with voids (9). The tread (4) comprises a circumferential groove (10) at at least one axially outermost end (4a). Each protuberance (8) is disposed at the surface of a sidewall, the different protuberances being disposed regularly or irregularly and continuously or discontinuously between a point A and a point E. The inner wall (2a) of the carcass ply (2) of the tire is partially or entirely covered with at least one layer of a self-sealing composition (2b).

The present invention relates to a device for mounting tubeless tire comprising an elongated balloon having an opening attached to a bicycle tire valve. The balloon is fabricated from latex or any other suitable elastic material, and is filled with a tire sealant composition. Further, the ballon is designed to burst at a pressure of 15-40 psi.
