Pneumatic tyres for a vehicle

The tread profile has a profile strip (1) that is provided for delimiting a circumferential groove (3) in an axial direction, such that the width of tire groove (7) is smaller than the measured distance of profile strip. The measured width of tire groove is set within the range of 1-3 mm along extension direction. A recess (8) is extended at an end of the tire groove in an axial direction over an extension length (L), such that the width of recess is made less than the width of tire groove.
