The invention relates to a pneumatic tyre comprising a metal component, a textile component and a cured rubber component, wherein the cured rubber component contains carbon black and recovered filler material, which is obtained from pyrolyzed tyre rubber comprising lignin-based filler material. Upon pyrolysis, the presence of lignin-based filler material in a tyre rubber may be used for adjusting the morphology and overall bulk density of the recovered filler material. Use of recovered filler material in a rubber component of a pneumatic tyre reduces the use of virgin feedstock materials.
