Beschreibung
Zusammenfassung:	A tire with in-situ generated two or more intrinsic puncture sealant layers based on ionic butyl with two or more different viscosities comprising a supporting tire carcass having one or more layers of ply, an outer circumferential tread, and a radially inner layer, a pair of beads, sidewalls extending radially inward from the axial outer edges of a tread portion to join the respective beads, a sealant comprising an outer layer of sealant and an inner layer of sealant, disposed radially inwardly from the radially inner layer of the tire carcass, wherein the outer layer of sealant and the inner layer of sealant have different viscosities, wherein the sealant provides self-sealing properties to the tire, and wherein the inner layer of sealant is cross-linked to the outer layer of sealant with no barrier separating the inner and outer layers of sealant.
