Energy saving tire with silica-rich tread
A pneumatic radial tire is provided with a tread having from 1 part by weight of hydrated amorphous fine-particle silica per 3 parts of carbon black tread reinforcing filler, to about 3 parts by weight of the silica to 1 part of the carbon black. The amount of silica present is preferably in the range from about 18 parts to about 50 parts by weight per 100 parts of natural or synthetic rubber. When such a tread is compounded with a mercaptosilane in which the mercapto group is reversibly blocked, the tread provides reduced rolling resistance without loss of traction. Such reduction in rolling resistance without loss of traction is not observed when the silica is not coupled with the mercaptosilane coupling agent.
