Abstract: A tire comprises an outer strip (2) having a tread (21). The outer strip (2) has a central part and two axially outer parts and comprises at least two rubber compounds (M1, M2) making up at least 90% of the volume of the outer strip (2). The first compound (M1) is radially on the outside of the second compound (M2), which makes up at least 60% of the axially outer parts and being disposed in a layer that is substantially continuous from one axially outer part to the other, said layer having a minimum thickness at least equal to 0.3 mm. The compound M1 has a modulus G* that is greater than 1.35 times and less than 3 times that of the compound M2. The compound M1 has a dynamic loss at 0° C. greater than 0.5 and the compound M2 has a dynamic loss at 23° C. less than 0.3.

Abstract: A rubber composition based on a reinforcing filler, an elastomer matrix that is reactive with respect to the crosslinking system, wherein the elastomer matrix comprises an elastomer A comprising monomer units of a first methacrylic acid ester which represent at least 20 mol % of the monomer units of the elastomer A, and a crosslinking system is provided. The rubber composition makes it possible to improve the wet grip of tires whose tread consists of the rubber composition.

Abstract: A tire tread that comprises a rubber composition based on an elastomer matrix that comprises more than 50% by weight of at least one butyl rubber, on a reinforcing filler and on a plasticizing system that comprises at least one polybutene oil having a glass transition temperature below ?75° C. A tire comprising such a tread has a good compromise between the wet grip performance and the rolling resistance performance.

Abstract: A tire tread that comprises a rubber composition based on an elastomer matrix that comprises more than 50% by weight of at least one butyl rubber, on a reinforcing filler and on a plasticizing system that comprises at least one phosphoric acid ester having a glass transition temperature below ?75° C. A tire comprising such a tread has both a low rolling resistance and a strong grip on wet ground.
