Abstract
A pneumatic tire includes a tread pattern having circumferential and lateral grooves forming a plurality of circumferentially extending ribs, each rib having a plurality of tread blocks. A plurality of tie bars extend circumferentially across certain of the lateral grooves between adjacent tread blocks in at least two of the ribs which are located equally opposite of a mid-circumferential plane of the tire. The tie bars have a pair of sidewalls and a sloped top surface with the slope of the top surface in one of the ribs being opposite to the slope of the tie bars in the other rib to generate a residual aligning torque (RAT) on the tire.
