Run strip profile of a vehicle tyre

摘要

The tread profile (1) has the profile blocks or tread strip bands (3) that are provided with the fine incision portions (2). The two axial sections (5,6) are formed in the fine incision portions along a common imaginary straight line at spacing (a). A central protrusion portion (7) with maximum extension (b), is formed between the axial sections. The spacing is set less than the maximum extension so that the undercuts are formed. The fine incision portions are provided with large width at specific regions.
