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.
