FIELD: tire production.

SUBSTANCE: present invention relates to a rubber composition for a tire, which is mainly intended for the use on a section of a tread of a pneumatic tire. This rubber composition contains, in diene rubber, from 30% by wt. to 50% by wt. of natural rubber and from 30% by wt. to 50% by wt. of butadiene rubber, a filler, and oil. Butadiene rubber is synthesized using a titanium catalyst. The filler contains carbon black and silica, wherein the total amount of carbon black and silica in the mixture is from 50 parts by weight to 100 parts by weight per 100 parts by weight of diene rubber. The total amount of the oil component containing oil is 15% or less of the total amount of carbon black and silica in the mixture.

EFFECT: development of a rubber composition for a tire, capable of providing significantly comparable characteristics on dry surface and characteristics on snow, as well as good extrudability.
