The present invention relates to a pneumatic tire having a non-spliced film innerliner comprised of a plurality of film layers where said film layers are of varied film moduli physical properties.

Techniques for managing tactical query to continuous query conversion are provided. In some examples, a tactical query configured to enable the pulling of business event data from a database to a query engine may be determined. For example, a query engine may be configured with the tactical query. The configuration may be based at least in part on an indication of the business event data to be displayed. Further, in some examples, a conversion of the tactical query to a continuous query may be enabled. The conversion or enablement of the conversion may be based at least in part on a request.

In a pneumatic tire production method including a step of overlapping end portions of a sheet laminate and vulcanization-molding the tire, the sheet laminate being obtained by layering an elastomer layer and a sheet of a thermoplastic resin composition containing a thermoplastic resin or a blend of a thermoplastic resin and an elastomer, after the end portions of the sheet laminate are overlapped, the overlapped portion of the sheet laminate is compression-bonded at a temperature of not less than a glass transition temperature Tg of the thermoplastic resin and not greater than 120 C.

In a pneumatic tire having a lap-splice portion in which an end section of a sheet laminate obtained by laminating an elastomer sheet and a thermoplastic resin composition sheet comprising a thermoplastic resin or a blended product of a thermoplastic resin and an elastomer is superimposed with another end of the sheet laminate and molded; (a) a sheet laminate obtained by attaching the thermoplastic resin composition sheet and an elastomer sheet having a greater width in a tire circumferential direction than the thermoplastic resin composition sheet is used as the sheet laminate; and (b) an excess width portion on at least one side of the elastomer sheet is folded back to a side of the thermoplastic resin composition sheet, and the folded back portion is superimposed with another end as an end section of the sheet laminate and molded.

Elastomer composition having a self-sealing property which can be used in particular as puncture-resistant layer in an inflatable article, based on at least (phr meaning parts by weight per 100 parts of solid elastomer): a blend of at least two solid elastomers, a polybutadiene or butadiene copolymer elastomer, referred to as elastomer A, and a natural rubber or synthetic polyisoprene elastomer, referred to as elastomer B, the elastomer A: elastomer B ratio by weight being within a range from 10:90 to 90:10; between 30 and 90 phr of a hydrocarbon resin; from 0 to less than 30 phr of filler. Inflatable article, such as a tire, provided with a puncture-resistant layer comprising this elastomer composition; the puncture-resistant layer is advantageously used in combination with an airtight layer, for example based on butyl rubber or TPS elastomer, in order to form, in the inflatable article, an airtight and puncture-resistant laminate.

The strip is formed of a single layer including a first layer arranged in a tire innermost layer or composite layers of the first layer and a second layer disposed adjacently to a carcass ply and made of a thermoplastic elastomer composition. The first layer is a thermoplastic elastomer composition containing a styrene-isobutylene-styrene block copolymer and a tackifier, a butyl-based rubber and a natural rubber. The strip has a strip main body having a thickness (T1) of 0.02 to 1.0 mm and ear portions formed on opposite sides of the strip main body. The ear portions have a thickness (T2) smaller than the thickness (T1) and a width (W2) of 0.5 mm to 5.0 mm.

A pneumatic tire for resonance noise reduction, which includes a plurality of resonance noise-reducing members that are disposed along the circumferential direction of the inner liner of a tire, and are formed to protrude from the inner liner so as to reduce the interference of the resonance noises generated inside the tire. The resonance noise-reducing members are formed at an irregular interval of disposition along the circumferential direction of the inner liner. Because the resonance noise-reducing members are formed integrally with the inner liner of a tire, the resonance noise-reducing members can be prevented from falling off from the tire even during high-speed driving of the vehicle, and can reduce the resonance noises generated inside the tire by reducing the phenomenon of resonant vibration occurring inside the tire. Thus, safe driving can be realized, with reduced disturbances caused by noises made during vehicle driving.

Provided is a pneumatic tire having improved air permeability resistance by improving adhesive property between an inner liner and a tire component adjacent thereto, reduced rolling resistance, and improved low temperature durability. The inner liner is composed of a polymer layer stack including a first layer containing an SIBS and a second layer containing at least one of an SIS and an SIB. At least one of the first layer and the second layer is a polymer composition containing one of a C4 polymer obtained by polymerizing a monomer unit having 4 carbon atoms, a layered clay mineral with an organic compound intercalated therein and at least one kind of rubber component selected from the group consisting of a natural rubber, an isoprene rubber and a butyl rubber. The second layer is arranged to come into contact with a rubber layer of the carcass ply. The inner liner has a thickness Ge at a shoulder position Pe exceeding 100% and being less than or equal to 500% of a thickness Gc at a crown central position Pc.

The present invention is directed to a method of cleaning an innermost surface of a pneumatic tire, the surface having a residue deposited thereon, comprising the steps of: activating a laser to generate laser radiation; directing a pulse of laser radiation to impinge on an area of the innermost surface, the pulse of radiation having a pulse width and a fluence sufficient to remove at least part of the residue in the area to form a cleaned area; repeating the step of directing the pulse of radiation sequentially over the innermost surface to form a sequence of cleaned areas, the sequence of cleaned areas defining a stripe, the stripe following a continuous nonlinear path extending at least one circumference about the inner surface, the stripe having a stripe width W2. The invention is further directed to a tire made by the method.

The disclosed technology generally relates to apparatuses for reducing or cancelling noise generated by a tire in motion, and more particularly to a noise-reducing apparatus including a sound-absorbing foam and a fixing structure for attaching and fixing the sound-absorbing foam to a tire. In one aspect, the noise-reducing apparatus for a tire includes a sound-absorbing foam configured to reduce noise generated by the tire by absorbing sound generated by the tire in motion when attached to an inner liner of a tire. The noise-reducing apparatus additionally includes a plurality of fixing bands configured to fix the sound-absorbing foam to an inner side of the tire. Each of the fixing bands has an attaching portion configured to be fixed to the inner side of the tire and has a pressing portion configured to bring and keep the sound-absorbing foam in contact with the inner liner. The pressing portion is configured to apply an elastic force on the sound-absorbing foam by extending and contracting. The disclosed technology also relates to a tire having the noise-reducing apparatus and a method of integrating the noise-reducing apparatus to a tire.
