The invention relates to a rubber composition comprising a rubber component that comprises at least one halobutyl rubber selected from the group consisting of bromobutyl rubber and chlorobutyl rubber; and a filler component that comprises at least one filler F1 which has a 14C content in the range of 0.20 to 0.45 Bq/g of carbon; a carbon content in the range of 60 wt. % to 85 wt. % relative to the ash-free and water-free filler; an STSA surface area in the range of 10 m2/g of filler to 50 m2/g of filler; and acidic hydroxyl groups on its surface; and wherein the proportion of halobutyl rubber in the rubber composition is 70 to 100 phr. The invention further relates to a vulcanisable and a vulcanised rubber composition based on the aforementioned rubber composition, a kit of parts for preparing the vulcanisable rubber composition, and methods for preparing the rubber composition and the vulcanisable rubber composition. Furthermore, the invention relates to a method for further processing the vulcanisable rubber composition, wherein webs are formed which are suitable, when cut to size, for use as inner liners in a method for manufacturing a pneumatic tyre. The invention also relates to the use of the aforementioned hydrothermally carbonised lignin for the preparation of rubber compositions for inner liners.
