Claims14
A tire mold for manufacturing at least one pneumatic tire, the tire mold comprising an annular base part comprising two or more recesses,
- wherein a first recess of the two or more recesses has a first recess shape S1 and
- wherein a second recess of the two or more recesses has a second recess shape S1′ different from the first recess shape S1, and
- two or more plaques,
- wherein a first plaque of the two or more plaques has a first plaque shape S2 comprising a negative shape of the first recess shape S1, such that the first plaque is insertable into the first recess of the base part,
- wherein a second plaque of the two or more plaques has a second plaque shape S2′ comprising a negative shape of the second recess shape S1′, such that the second plaque is insertable into the second recess,
- wherein at least one of the two or more recess shapes is asymmetric to a plane spanned by the central axis of the annular base part and a straight line perpendicular to the central axis through the geometric center point of the at least one of the two or more recess shapes, and
- wherein at least one of the two or more recess shapes comprises a geometry composed of at least one hole and a long hole or of at least two long holes, wherein the holes all have different hole diameters.
