Abstract
A tire having a mid-circumferential plane and comprising a plurality of circumferentially arranged tread blocks for contacting a road surface. Surfaces define a pair of substantially parallel grooves extending transverse to the mid-circumferential plane of the tire for at least partially defining each of the tread blocks. A channel separates each respective one of the plurality of tread blocks into a pair of tread elements. A first channel in a first tread block is oriented at a first angle relative to the mid-circumferential plane of the tire. The first angle varies from second and third angles at which second and third channels in respective second and third tread blocks adjacent the first tread block are oriented relative to the mid-circumferential plane of the tire.
