    Abstract: A halobutyl rubber is generally used in the innerliner of pneumatic tires to retard the escape of air used to inflate the tire, thereby maintaining tire pressure. Since halobutyl rubbers, such as bromobutyl rubber, are generally the most expensive elastomers used in tires, it is desirable from a standpoint of cost reduction to reduce the level of halobutyl rubbers used in tires. The present invention relates to a technique for reducing the quantity of halobutyl rubber utilized in the innerliner of tubeless pneumatic vehicle tires. The present invention more specifically relates to a tire innerliner and pneumatic tires containing the same, which are prepared from a composition comprising, based on 100 parts by weight of rubber, a blend of (1) about 50 parts to about 90 parts of a halobutyl rubber and (2) about 10 parts to about 50 parts of a styrene-isoprene-butadiene terpolymer rubber having a first glass transition temperature which is within the range of about -110.degree. C. to about -20.degree. C. and a second glass transition temperature which is within the range of about -50.degree. C. to about 0.degree. C., wherein said styrene-isoprene-butadiene terpolymer rubber contains about 20 weight percent to about 40 weight percent bound styrene.

    Abstract translation: 通常，在充气轮胎的内衬层中使用卤代丁基橡胶，以阻止用于使轮胎充气的空气的逸出，从而保持轮胎压力。 由于卤代丁基橡胶（例如溴丁基橡胶）通常是轮胎中使用的最昂贵的弹性体，因此从成本降低的观点来看，期望降低轮胎中使用的卤代丁基橡胶的含量。 本发明涉及减少无内胎气动车辆轮胎的内衬中使用的卤代丁基橡胶的量的技术。 本发明更具体地涉及一种包含其的轮胎内衬和充气轮胎，其由基于100重量份橡胶的组合物制备，（1）约50重量份至约90重量份的卤代丁基 橡胶和（2）约10份至约50份第一玻璃化转变温度在约-110℃至约-20℃范围内的苯乙烯 - 异戊二烯 - 丁二烯三元共聚物橡胶和第二玻璃 转化温度在约-50℃至约0℃的范围内，其中所述苯乙烯 - 异戊二烯 - 丁二烯三元共聚物橡胶含有约20重量％至约40重量％的结合苯乙烯。

    Abstract: The innerliner ply of a tire has been modified in thickness to provide a profiled innerliner ply. A permeability relationship is established for the material of the innerliner that allows the average thickness of the innerliner ply to be adjusted based on its temperature. The maximum and minimum thickness are located in relation to the maximum and minimum internal temperature locations within the tire. A gradual change in thickness is used between the maximum and minimum thickness locations. An object of the invention is to limit the air flow through the tire in locations which have a high internal temperature. This limited air flow will improve the deterioration of rubber products in the tire and maintain an allowable inflation pressure air loss rate.

    Abstract: A pneumatic tire is disclosed, which comprises a carcass composed of at least one ply and an inner liner arranged inside the carcass and composed of plural rubber layers. In the tire of this type, the inner liner comprises at least three layers of an outermost layer adjacent to the carcass, an innermost layer facing the inner space of the tire and an intermediate layer interposed between the innermost and outermost layers. The innermost layer is composed of a rubber composition containing 15-60 parts by weight of natural rubber and the balance of a halogenated butyl polymer as a rubber component, while the intermediate layer is composed of a rubber composition containing only a halogenated butyl polymer as a rubber component, which is different from that of the outermost layer in the rubber component.

    Abstract: Disclosed herein is a pneumatic tire comprising a carcass composed of at least one cord ply extending between a pair of bead portions, an inner liner adhered to the inner surface of the carcass, and a rubber reinforcing layer made of a rubber composition different from and having a Shore A hardness higher than that of the inner liner and disposed at a lower part of the bead portion including a bead toe portion and a bead heel portion to form an outermost bead rubber at least at that region of the bead portion which comes into contact with a rim. In the tire, the rubber reinforcing layer is divided into an axially inside portion inclusive of the bead toe portion and an axially outside portion at a boundary surface located in an area between the bead toe portion and a position corresponding to 1/2 of a height of a rim flange, and the axially outside portion is extended over the height of the rim flange outwardly in the radial direction of the tire, and rubber of the axially inside portion is small in the Shore A hardness and abrasion resistance index and high in the breaking energy after heat deterioration as compared with that of the axially outside portion.
