In another embodiment, a TPV composition includes an ethylene based copolymer, a thermoplastic polyolefin, and one or more of an oil or a plasticizer. The ethylene based copolymer has an Mw of from 400,000 g/mol to 3,000,000 g/mol, a Mw/Mn of 10 or less, and a g.sub.vis of 0.7 or more. An amount of the one or more of an oil or a plasticizer in the TPV composition is from 10 parts by weight to 200 parts by weight per 100 parts by weight of the ethylene based copolymer, and the TPV composition has an extrusion surface roughness that is from 50 in to 120 in. In another embodiment is provided a method of forming a TPV composition. In another embodiment is provided a method of forming an article that includes a TPV composition. In another embodiment is provided an article that includes a TPV composition.

The present invention relates to a tyre (10) comprising, in the beads or in the tread, a rubber composition based on: an elastomeric matrix predominantly by mass comprising natural rubber; at least 65 phr of reinforcing fillers, the reinforcing fillers consisting of 40 to 70 phr of pyrolysis carbon black and 10 to 40 phr of carbon black, the ratio (mass of pyrolysis carbon black)/(total mass of reinforcing fillers) ranging from 0.60 to 0.75; 10 to 20 phr of a reinforcing resin mixture, the reinforcing resin mixture comprising a cardanol-based phenolic resin, the ratio (mass of cardanol-based phenolic resin)/(total mass of reinforcing resins) ranging from 0.1 to 0.7; a curing agent; and a crosslinking system.
