摘要:
A pneumatic tire having a carcass (22) comprising at least two inner plies (1, 2, 3, 4) is disclosed. At least one inner ply (1, 2, 3, 4) is wound about an annular bead member (14) from axially inside of the annular bead member (14) toward axially outside thereof and extends radially outward towards a tread portion (20) of the tire (10) forming a respective turnup portion (1', 3', 4'). Furthermore, at least one of the inner plies (2) has a terminal end (2') which has a radial location in a first zone (C) defined by a first plane (28) and a second plane (29), wherein the first plane (28) is tangent to the outer radial surface of the annular bead member (14) and parallel to the axis of rotation of the tire (10), wherein the second plane (29) is perpendicular to the first plane (28) and extends through the center of the annular bead member (14), and wherein the first zone (C) is located radially inward of the first plane (28) and axially outward of the second plane (29). Preferably, the tire (10) is an aircraft tire.
