The present invention provides workability, low fuel consumption property, rubber strength, the rubber composition abrasion resistance and wet grip performance can be a good balance improved, and a pneumatic tire using the same.
The present invention relates to active end of a copolymer obtained by polymerizing a monomer component containing a conjugated diene compound and a silicon-containing vinyl compound using a polymerization initiator represented by the following formula (I), the nitrogen atom and / or a conjugated diene-based polymer obtained compounds containing a silicon atom is reacted, the nitrogen adsorption specific surface area and a silica 40 to 400 2 /
g, in 100% by mass of the rubber component, the above-mentioned conjugated diene-based heavy content of 1 to 60 wt% of coalescing, is 0 to 99 wt% content of polyisoprene rubber, the content of the silica to 100 parts by mass of the rubber component is 10 to 80 parts by mass, carbon ratio It relates to a rubber composition but is 50 or more.
