A pneumatic tyre (500) defining a wear indicator (510). The tyre (500) may have been manufactured by inserting rods (200) of a mould into the tire tread (505) during manufacturing. A mould (100) for the purpose comprises at least seven rods (200) extending in parallel in a direction (SZ) of height on a same side of an object (110, 160) and connected to the object (110, 160). The rods (200) are arranged such that multiple distances are left in between the cross sections (300, 301) of the rods (200, 201) and a minimum of the multiple distances (d i,j (z)) is at least 0.5 mm. In the direction (SZ) of height, the cross section (300) and/or the height of at least some of the rods (200) varies in such a way, that at a number of different height positions, the cross sections (300) of the rods (200) at those height positions define that number of different mirror-image symbols (120), of which mirror images are expressible by the wear indicator (510), one mirror-image symbol (120) corresponding to one height position, the number of different height positions and mirror-image symbols being at least two.
