摘要： A tire includes a circumferential regional tire tread having a central region and first and second shoulder regions adjacent the central region. A circumferential array of spaced apart shoulder sipes is formed within one or both of the shoulder regions, each of the shoulder sipes having a depth in an unworn tire tread condition within a depth range of from 1 mm to 3.5 mm, and each shoulder sipe having a longitudinal axis oriented in a substantially axial direction within a range of between 20 degrees of the tire axial direction. The shoulder sipes each include a first and a second straight segment intersecting at an end-to-end intersection with respect to each other at an intersection angle. The first and second straight segments of each shoulder sipe incline in opposite directions from the end-to-end intersection and the end-to-end intersection of each shoulder sipe is located at a circumferential shoulder groove within a respective shoulder region.
