PROBLEM TO BE SOLVED: To provide a pneumatic tire having a tread rubber composition for a tire having wet skidding resistance, low rolling resistance, good wear characteristics and low temperature traction force suitable for driving on snow. SOLUTION: Solution-polymerized styrene-butadiene rubber up to 100 phr; based on 100 parts by weight (phr) of elastomer; [In the formula, R 1 is derived from the linear or branched alkyl of C1 to C8, the linear or branched alkenyl of C1 to C8, and the linear or branched alkyl of C2 to C6 substituted with 1 to 5 hydroxyl groups. Selected; R 2 is a C11-C21 alkyl or C11-C21 alkenyl] fatty acid monoester 5-50 phr; Hydrocarbon resin 5-50 phr with Tg in the range of -40 ° C to 20 ° C; Petroleum-derived oil less than 10 phr; and silica 50-130 phr, Optionally, carbon black about 1-50fr A pneumatic tire having a tread containing a vulcanizable rubber composition comprising.
