摘要： A tire (100), which has a maximum section width (W m ), an upper section (U) above the maximum section width (W m ), and a lower section (L) below the maximum section width (W m ), includes a tread (102) extending circumferentially about the tire (100), a pair of sidewalls (104), a pair of bead portions (106), and at least one carcass ply (114, 116) extending circumferentially about the tire (100) from one bead portion (106) to the other. The tire (100) further includes a reinforcement ply (144) extending circumferentially about the tire (100) and being disposed between the at least one carcass ply (144) and tread (102) and at least one of the sidewalls (104) of the tire (100). The reinforcement ply (144) has a lower end (208) that terminates in the lower section (L) of the tire (100). The reinforcement ply (144) comprises two arrays of cords (302, 304) spaced apart from each other, wherein the cord (302, 304) in the respective arrays or rows a orientated parallel to each other. The reinforcement ply (144) is not wound around the bead cores (108) and thus forms a so called floating ply. The bead filler insert (202) is spaced from the bead filler (110) by a gap consisting of rubber material.

摘要： A tire (100), which has a maximum section width (Wm), an upper section (U) above the maximum section width (Wm), and a lower section (L) below the maximum section width (Wm), includes a tread (102) extending circumferentially about the tire (100), a pair of sidewalls (104), a pair of bead portions (106), and at least one carcass ply (114, 116) extending circumferentially about the tire (100) from one bead portion to the other. The tire (100) further includes first and second reinforcement plies (202, 204) extending circumferentially about the tire (100) and being disposed between the at least one carcass ply (114, 116) and the tread (102) and at least one of the sidewalls (104) of the tire (100). The first and second reinforcement plies (202, 204) have lower ends (208, 212) that terminate in the lower section (L) of the tire (100).

摘要： A tire, which has a maximum section width, an upper section above the maximum section width, and a lower section below the maximum section width, includes a circumferential tread, a pair of sidewalls, and a pair of bead portions. The tire further includes at least one carcass ply extending circumferentially about the tire from one bead portion to the other and first and second reinforcement plies extending circumferentially about the tire. The first and second reinforcement plies are provided between the at least one carcass ply and at least one of the sidewalls of the tire. The first and second reinforcement plies include lower ends that terminate in the lower section of the tire and upper ends that terminate in the upper section of the tire.
