摘要： The present invention provides a tire with excellent durability having an overlap splice portion in which an inner liner configured from a film whose main component is thermoplastic resin is adhered to an inner side of a carcass layer of a tire via a tie rubber sheet and end portions in a tire circumferential direction of the film overlap via a tie rubber across a tire width direction, wherein a crack is not generated near an overlap splice portion of an inner liner layer, after the pneumatic tire has started traveling. The pneumatic tire of the present invention includes: (a) a surface on a tire cavity side of a film positioned on a tire cavity side in the overlap splice portion is formed with a recess so that a film thickness at the overlap splice portion becomes thinner than a film thickness of portions other than the overlap splice portion, (b) a surface on a tire outer circumferential side of the film positioned on the tire cavity side in the overlap splice portion is formed flat between the overlap splice portion and the portions other than the overlap splice portion, and (c) a surface on a tire cavity side and a surface on a tire outer circumferential side of a film positioned on a tire outer circumferential side in the overlap splice portion are formed flat between the overlap splice portion and the portions other than the overlap splice portion.

摘要： Provided is a pneumatic tire including an inner liner layer formed from a laminate sheet obtained by laminating: a sheet made from a thermoplastic resin or a thermoplastic resin composition which is a blend of the thermoplastic resin and an elastomer; and a rubber bonded by curing to the thermoplastic resin or the thermoplastic resin composition. The pneumatic tire avoids occurrence of cracks near a splice portion of the inner liner layer after the pneumatic tire starts to be used for driving, and thereby achieves excellent durability. In the pneumatic tire, an inner liner layer 10 is formed by lap-splicing end portions of a laminate sheet 1 which is obtained by laminating: a sheet 2 made from a thermoplastic resin or a thermoplastic resin composition which is a blend of the thermoplastic resin and an elastomer; and a rubber 3 to be bonded by curing to the thermoplastic resin or the thermoplastic resin composition. Here, a sheet with end portions each having a tip subjected to a tip sharpening process is used as the sheet 2 made from the thermoplastic resin or the thermoplastic resin composition which is the blend of the thermoplastic resin and the elastomer.

摘要： A strip of a thermoplastic elastomer to be wound spirally on a cylindrical drum for forming an inner liner for a tire having a shape close to a finished sectional shape is provided. The strip is formed of composite layers of (A) a first layer made of a styrene-isobutylene-styrene triblock copolymer and (B) a second layer containing at least one of a styrene-isoprene-styrene triblock copolymer and a styrene-isobutylene diblock copolymer. The strip further has a strip main body and ear portions arranged on opposite sides thereof. The strip main body has a thickness (T1) of 0.05 mm to 1.0 mm. The ear portions have a thickness (T2) thinner than the thickness (T1) of the strip main body and a width (W2) of 0.5 mm to 5.0 mm. This ribbon-shaped strip reduces unevenness of the surface of a sheet formed by the opposite ends of the strip when manufacturing an inner liner.

摘要： This disclosure is directed to a method of preparing a continuous elastomeric length for a pneumatic innerliner comprising providing a continuous elastomeric length comprising a plasticizer and an elastomer; heating the continuous elastomeric length for a residence time at a temperature no higher than 15°C above the flash point of the plasticizer; and cooling the length to form a heat-treated continuous elastomeric length having a level of plasticizer less than the level of plasticizer in the continuous elastomeric length. In certain embodiments, the heat-treated continuous elastomeric length or laminate comprising the heat-treated continuous length can be first cut to form a pneumatic innerliner unit, and splicing the pneumatic innerliner unit to itself to form a pneumatic innerliner. The heat-treated continuous elastomeric length or laminate comprising the heat-treated continuous length can be cut into the form of a sleeve to form a pneumatic innerliner sleeve, and the sleeve incorporated into a tire.
