<p>Vehicle pneumatic tire comprises a radial carcass, a belt and a tread which comprises two layers made of different rubber mixtures, a tread cap and a tread base in the radial direction, where the tread cap represents the part of the tread which is in contact with the road and the tread base is arranged between the tread cap and the belt. The tread base is based on a rubber mixture, which comprises: more than 70 phr natural and/or synthetic polyisoprene; 21-42 phr silicic acid and carbon black; and at least one coupling agent for bonding the silicic acid to the rubber. Motor vehicle pneumatic tire comprises a radial carcass, a belt and a tread which comprises two layers made of different rubber mixtures, a tread cap and a tread base in the radial direction, where the tread cap represents the part of the tread which is in contact with the road and the tread base is arranged between the tread cap and the belt. The tread base is based on a rubber mixture, which comprises: more than 70 phr natural and/or synthetic polyisoprene; 21-42 phr silicic acid and carbon black, where the ratio of silicic acid to carbon black is greater than 1:1; and at least one coupling agent for bonding the silicic acid to the rubber.</p> |
