description	The invention discloses a self-sealing tire. The invention relates to a pneumatic tire consisting of a substantially annular support carcass having an outer circumferential tread, two spaced apart beads, at least one ply extending from the beads to the beads, sidewalls extending radially from the tread to the beads and connecting them, a sealant layer disposed inwardly from the support carcass, and an inner liner disposed inwardly from the sealant layer, wherein the circumferential tread is adapted to contact the ground, and wherein the sealant layer comprises a polyisobutylene or butyl rubber wherein the polyisobutylene or butyl rubber has a number average molecular weight of 30,000 to 100,000. A method of manufacturing a pneumatic rubber tire having a puncture sealing feature is also disclosed. The sealant layer in such a tire typically has a storage modulus (G ') at 40 DEG C, 1 Hz and 5% strain of 0.005 to 0.2 MPa as measured by RPA. 本发明公开了自密封轮胎，其由具有外圆周胎面的大致环形的支撑胎体、两个间隔的胎圈、至少一个从胎圈延伸至胎圈的帘布层、由所述胎面径向延伸至所述胎圈并连
