Abstract

PURPOSE: To improve the rolling resistance and running stableness by constituting the tread by a mixture obtained by mixing at a certain rate a natural rubber or a diene system rubber, a styrene-butadiene copolymer of a predetermined composition and a vulcanized powder of acrylonitrile-butadiene copolymer.
CONSTITUTION: The tyre tread part is made of a rubber composition vulcanized and mixed with 5W50pts.wt. of vulcanized powdery rubber which comprises 100pts.wt. of natural rubber and/or diene system synthetic rubber, the styrene-butadiene copolymer rubber containing 30W50wt% of styrene and/or the acrylonitrile- butadiene copolymer rubber containing 25W45wt% of acrylonitrile. The tyre having the above composition can be improved in the rolling resistance and the running stableness such as the wet skidding and wet braking characteristics.
