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 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.
