    摘要: The present invention relates to a pneumatic tire with a built-in depolymerized sealant layer. The built-in sealant layer is of a composition comprising a partially depolymerized butyl rubber or alternatively a composite of partially depolymerized butyl rubber, together with partially depolymerized cis 1,4-polyisoprene rubber and/or partially depolymerized liquid polyisoprene polymer, which contains a pre-hydrophobated silica. The sealant layer may also contain a colorant of a non-black color which produces a built-in sealant layer of a color which contrasts with a black. The butyl rubber-based sealant precursor is built into the tire as a layer to form a tire assembly including such sealant precursor layer wherein the butyl rubber or butyl rubber-based composite portion of the sealant precursor layer is at least partially depolymerized during a subsequent curing of the tire at an elevated temperature in a suitable mold to form the tire having the resultant built-in sealant layer.
