摘要： Tire tread having a central part (I) made from at least one first rubber compound and having at least one circumferential rib (121-123) formed of a plurality of blocks (1210) separated by sipes; a first and a second lateral part (II and III) made of at least a second and third rubber compound, and having a circumferential rib (131,141) formed by a plurality of blocks (1310,1410), separated by sipes, wherein the at least one second and third rubber compounds have a value of tan δ at 23° C.—at a frequency of 10 Hz and an elongation of 10% —of less than 0.25, wherein the complex modulus G*(T) of the at least one first rubber compound is greater than the complex moduli G*(T) of at least one second and third rubber compounds for all temperatures T greater than or equal to 0° and less than or equal to 60° C.
