    Abstract: The invention relates to a tyre (1), the tyre (1) comprising: a tread (2) having a tread surface (3) for contacting the ground and at least one groove-like recess (4) therein forming a free space (5), the recess (4) having a longitudinal extension A along the surface (3) and a depth B measured in a radial direction with respect to a radial axis (X) of the tyre (1) from the tread surface (3) to a radially innermost position (19), wherein the free space (5) can be divided into a sipe portion (6) opening to the tread surface (3) and a groove portion (7) located radially inwards the sipe portion (6), wherein in a cross sectional view transverse to the longitudinal extension A of the recess (4) the groove portion (7) has a groove contour (9), with a longitudinal axis (X′), wherein a corresponding width of the groove contour (9) has a local maximum Wg at a height H referred to a spatial extent E of the groove contour (9) in the direction of this longitudinal axis (X′) and wherein the groove portion (7) has at least one transition section along the longitudinal extension A of the recess (4), between the ends (17, 18), wherein the height H of the groove portion (7) changes by an amount ΔH. The invention further relates to a corresponding wheel for an automobile comprising such kind of tyre (1), a blade (11) for forming a part of a corresponding tyre moulding form and a corresponding moulding form.
