ABSTRACT A tire having a longitudinal central axis about which the tire is rotatable. The tire includes a pair of axially spaced rim beads. A carcass extends between and is connected at opposite ends to the rim beads. Each of a pair of axially spaced ground engaging tread portions includes an annular reinforcing member having substantially inextensible and parallel extending cords disposed at an acute angle relative to the mid-circumferential plane of the tire. The cords in the annular reinforcing member in one of the pair of tread portions extend in an opposite direction to the cords in the annular reinforcing member in the other of the pair of tread portions to minimize ply steer. A central portion is located intermediate the pair of tread portions and includes a surface defining a circumferentially extending groove. A central member has a substantially annular configuration in an unloaded condition. The central member has an outer diameter greater than the outer diameter of either of the rim beads and less than the inner diameter of the annular reinforcing member. The central member is located radially inward of the groove in the central portion and is deflectable from the annular configuration as the tire rotates through a footprint. dlh/1613 - 6/18/90
