A low rolling resistance tire for vehicles includes a carcass structure, a belt structure coaxially extending around the carcass structure, and a tread coaxially extending around the belt structure and being externally provided with a rolling surface designed to contact the ground. The tread includes a vulcanized polymer base having at least a first silica-based reinforcing filler. The first silica-based reinforcing filler has an average projected area of aggregates, measured before incorporation into the polymer base, lower the 20,000 nm , a dispersion index in the polymer base not lower than 97%, and an average projected area of the aggregates, measured after incorporation into the polymer base, between 8,500 nm and 18,000 nm .
