Abstract:
A vulcanizable rubber composition comprising:a. cross-linkable unsaturated chain polymeric base, and b. from 2 to 30 parts by weight of the polymeric base of at least one polymeric organic compound solid at room temperature and having a glass transition temperature of from 80 to 160Â° C. and an average molecular weight of from 10,000 to 1,000,000, said polymeric organic compound being substantially insoluble in said polymeric base, wherein the rubber composition has, once vulcanized, a first hysteretic behavior at a first working temperature of a tire having a thread made of the composition and a second hysteretic behavior, which differs from the first hysteretic behavior, at a second working temperature of the tire.
