A tread profile has a tread profile section which is in the center of the tire in the axial direction, and in each case one shoulder profile section. The central tread profile section is composed of profile belts, and the shoulder profile sections each have a second profile belt. A circumferential groove is arranged in each case between a first profile belt of the central section and the profile belt of the shoulder section. The groove is formed with a web which is radially raised from the groove base and which divides the groove into a narrow first and a wider second section which has, at the groove base, a linear section of extent which merges, with a curvature radius R3 and R2, with the edges of the profile belt or of the web, wherein R3>R2. The linear section of extent is at an angle of inclination >0°. |
