PURPOSE: To provide a method for determining a split part of a traveling surface to an oblique groove profile of a pneumatic tire of an automobile in consideration of characteristics of the tire such as drain performance, noise generation or the like. CONSTITUTION: A traveling surface is divided into V-shaped split modules. The module has one split part element each on right and left with respect to the traveling center area, and a number of split part elements are provided in a shoulder area. The minimum width BKPU of the split part element of the shoulder area, the inclination azimuthsα,βof the center area and the shoulder area of the traveling surface, the width BRsch of the shoulder rib and the split shifting V are found by a designated formula. |
