Abstract: The present invention relates to a winter tyre for vehicles comprising a tread band obtained by vulcanisation of a new elastomeric composition. Said elastomeric composition comprises among the others a plasticising mixture of liquid polymer (A), resin (B) and possibly plasticising oil (C). Said winter tyre, in addition to excellent driving and braking on snow and at low temperatures, surprisingly exhibits an optimal balance of notoriously conflicting properties, such as the behaviour on wet and dry.

Abstract: Tyres for vehicle wheels, in particular high and ultra high performance tyres are described along with a process for the manufacturing thereof. These tyres comprise one or more components with high rigidity and are particularly high- performing in road behaviour. Due to the use of particular stabilised co-vulcanising compositions in the mixtures of such components, it has been possible to increase the rigidity of the same and simultaneously prevent the release of irritating by-products during manufacturing, in particular during the step of calendering the rubber-covering mixtures of the cords.
