LOW ROLLING RESISTANCE TIRE FOR VEHICLES |
摘要 |
A low rolling resistance tire (1) for vehicles is described which comprises a belt structure (12) coaxially extending around a carcass structure (2) and a tread (9), coaxially extending around the belt structure (12) and being externally provided with a rolling surface (9a) designed to get in touch with the ground, the tread (9) comprising a vulcanized polymer base including at least a first silica-based reinforcing filler, the tire being characterized in that the first silica-based reinforcing filler has: an average projected area of the aggregates as measured before incorporation into the polymer base lower than 20,000 nm<2>; a dispersion index in the vulcanized polymer base of the tread (9) not lower than 97 %; and a projected area of the aggregates after incorporation into the polymer base comprised between 8500 and 18000 nm<2>. Advantageously, said tire has mechanical properties improved or at least comparable with respect to those of the known tires for the same type of use. |
