A rubber compound for treads comprising a styrene-butadiene rubber (SBR), carbon black and a vulcanization system. The filler comprises 5 to 30 phr of a thermoplastic polymer, preferably polylactic acid, having a Tg ranging from 50 to 70&#xb0; C., a molecular weight (Mw) not exceeding 200,000 g/mol and a crystallinity not exceeding 0%.

Rubber compound to produce treads

A rubber compound for tyres comprising a cross-linkable unsaturated chain polymer base comprising, in turn, at least a rubber of synthetic origin, a silica-free filler at least partially comprising carbon black, a vulcanization system and a mercapto carboxylic acid.

Rubber compound for tyre production

A tire portion selected from the group including an innerliner, tread ply skim, TBR body ply skim, bead reinforcing skim, undertread, tie gum, squeegee, folded edge gum strip, belt edge gum strip and tread ply insert, and made from a compound including a polymer base and curing agents. The compound also includes a carbohydrate having 2 to 30 repetitive, possibly substituted, units.

Tyre portions highly impermeable to oxygen

A tire rubber compound having at least one cross-linkable, unsaturated-chain polymer base, and a curing system of at least sulphur, stearic acid, zinc oxide, and a chelating agent for complexing the zinc ion.
