    • The present invention is directed to a pneumatic tire having a built-in sealant layer and its preparation. In one embodiment, the pneumatic tire includes an outer circumferential rubber tread and a supporting carcass. An optional rubber inner liner is disposed inwardly from the supporting carcass. A built-in sealant layer is disposed inwardly from the rubber inner liner. The built-in sealant layer provides self-sealing properties to the pneumatic tire. A gas permeable layer is situated adjacent an innermost rubber inner liner and the built-in sealant layer. The innermost rubber inner liner has a plurality of spaced apart openings extending therethrough, which are covered by the gas permeable layer. The tire, with its innermost inner liner with holes and the gas permeable layer, allows for elimination or reduction in blister formation in the tire by permitting gas from the built-in sealant layer to escape.
    • 本发明涉及一种具有内置密封剂层的充气轮胎及其制备方法。 在一个实施例中,充气轮胎包括外周橡胶胎面和支撑胎体。 可选的橡胶内衬从支撑体向内设置。 内置的密封剂层从橡胶内衬内侧设置。 内置的密封剂层为充气轮胎提供自密封性能。 透气层位于最内侧的橡胶内衬和内置的密封层附近。 最里面的橡胶内衬具有多个间隔开的开口,这些开口被透气层覆盖。 具有孔的最内侧内衬和透气层的轮胎允许通过允许来自内置密封剂层的气体逸出来消除或减少轮胎中的气泡形成。

    • An automobile tire having fluid-tight internal partitions to form discrete internal compartments includes bead-like sub-structures provided within internal partitions having contact with a road during use of the tire, the bead sub-structures including a pressure-sensitive sealant in which a rapid change in air pressure in the tire induces activation of the sealant; and a tire wheel having a lateral surface complemental to an inner radial geometry of the tire, including, at an interface between the wheel and the tire, a pump for selectable inflation of at least one of the compartments. The system may also include inflatable wheel sealing ridges formed integrally within the tire, the ridges including circumferential annular fluid tight channels inflatable independently of inflation of the internal wheel partitions.
