Energy saving tire with large particle size, high structure carbon black in tread

Patent ·
OSTI ID:6078330

A pneumatic radial tire having reduced rolling resistance is provided. The tire has a novel tread composition comprising 100 parts by weight of rubber of which at least 90 parts by weight is cis-polyisoprene. The tread composition also has less than 10 parts by weight of processing oil and from 30 to 60 parts by weight of carbon black wherein said carbon black has a particle size greater than about 35 millimicrons and a dibutyl phthalate absorption value greater than 100.
