Pneumatic Tire Having Built-In Sealant Layer And Preparation Thereof

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. A rubber inner liner is disposed inwardly from the supporting carcass. A built-in sealant layer is situated adjacent an innermost gas permeable layer and disposed inwardly from the rubber inner liner. The built-in sealant layer provides self-sealing properties to the pneumatic tire. The tire, with its innermost gas permeable layer, allows for elimination or reduction in blister formation in the tire. The pneumatic tire can be prepared by positioning the gas permeable layer on a tire-building apparatus. Next, a precursor sealant layer is positioned directly on the gas permeable layer. The rubber inner liner is disposed outwardly of the precursor sealant layer followed by the tire carcass then the rubber tire tread on the tire carcass.

Pneumatic tire having built-In sealant layer and preparation thereof

A pneumatic tire is provided which includes an outer circumferential rubber tread and a supporting carcass. A rubber inner liner is disposed inwardly from the supporting carcass. A built-in sealant layer is situated adjacent to an innermost removable barrier layer and disposed inwardly from the rubber inner liner. The built-in sealant layer provides self-sealing properties to the pneumatic tire. The pneumatic tire, with its innermost removable barrier layer, keeps the sealant layer from sticking to a tire-building apparatus during tire assembly and, after curing of the assembled tire, is eventually removed to permit gas from the built-in sealant layer to become part of the tire's inflation air to prevent or reduce instances of inner liner blister formation.
