The tread pattern has multiple profile elements (1,3,5) that are formed of grooves (2,4,8) on a main extension of the outer surface. The extending portions (9,10) of the grooves extend along the main extension in a radial direction of a tire. The grooves are bounded on both sides of the groove bottoms, respectively by a groove wall. The cutting lines (v,w,g) extend and steadily increase toward the extension end of the grooves in the radial direction, such that the extension end of the outer surface intersects at an intersection point (S). |
