Tire with Intrinsic Sealant containing Intrinsic Cellular Innermost Layer

摘要

A tire with in-situ generated intrinsic puncture sealant layers and intrinsic noise damper 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 at least one layer of sealant, disposed radially inwardly from said radially inner layer of said tire carcass, an intrinsic cellular noise damper as the innermost layer adjacent to the sealant, wherein said noise damper has a density less than 1.3 g/cm³; and wherein said sealant provides self-sealing properties to the tire.
