Abstract: A pneumatic tire is provided with sipes, at least some of which have an open top end to the surface of the tread block. An intersection of the sipe with a surface that is geometrically congruent and parallel with the surface of the tread block and arranged a depth apart from the surface of the tread block into the tread block forms a curved line. A first sipe is shaped in such a way, that at all depths (d) within a range from the open top of the first sipe to a first transition depth, the curved line includes at least one deflection point having an inner corner that has a radius of curvature under 0.3 mm. A lamella plate for manufacturing the pneumatic tire, the tread band, or the tread block. Use of the lamella plate for manufacturing a tread block, a tread band, or a pneumatic tire.

Abstract: A pneumatic tyre with a wear indicator may be manufactured by inserting rods of a mould into the tire tread during manufacturing. A mould may include at least seven rods extending in parallel in a direction of height on a same side of an object and connected to the object. The rods are arranged so multiple distances are left between the cross sections of the rods and a minimum of the multiple distances ?0.5 mm. In the direction of height, the cross section and/or the height of at least some of the rods varies so at a number of different height positions, the cross sections of the rods at those height positions define that number of different mirror-image symbols, of which mirror images are expressible by the wear indicator, one mirror-image symbol corresponding to one height position, with at least two different height positions and mirror-image symbols.

Abstract: A vehicle tire (1), including a tread (2) which intended for rolling contact with a foundation, the tread 82) being formed with a tread pattern (20) which includes circumferential grooves (25) and transverse grooves (26) for removing water from a contact patch between the foundation and the tire (1). The circumferential groove (25) has its wall (251) formed with a flow deflector (259) reducing a width of the circumferential groove (25), commencing from the wall (251) of the circumferential groove (25), bypassing a reduced-width portion (250) of the circumferential groove (25), and continuing arcuately into the transverse groove (26) so as to turn into a wall (261) of the transverse groove (26).
