A tire (100) having a tread (80) with tread elements (84,86) which, when compressed in a radial direction, exhibit a net torque about the tire footprint. The net torque so generated can be directed and designed so as to affect the tire's residual self-aligning torque (also known RSAT). One embodiment of the invention features a tire tread (80) having a first tread element (84) and a second tread element (86). The first tread element (84) is on a first side (74) of the tire's circumferential centerline (CL) and has a first sidewall (92). The first sidewall (92) is a plane which makes an angle alpha 1 with a plane passing through the tire's axis of rotation. The second tread element (86) is on the second side (76) of the tire's circumferential centerline (CL) and has a first sidewall (102) which is in a plane making an angle alpha 2 with a plane passing through the tire's axis of rotation. The angle alpha 1 may be different from the angle alpha 2 or equal and opposite in sign. <IMAGE> |
