ABSTRACT A rubber composition comprising a natural and/or synthetic rubber, a filler and an acrylamide compound represented by the formula of X-NH?CH=CH2 wherein X is an aliphatic or alicyclic group, phenyl or phenoxyphenyl, in which said aliphatic or alicyclic group may contain halogen or oxygen in the group, said phenyl may be substituted once or twice by halogen, hydroxy, alkyl of 1 to 8 carbon atoms, alkoxy of 1 to 8 carbon atoms, nitro, cyano, carboxy or alkoxycarbonyl, and said phenoxyphenyl is represented by the formula of Image wherein Q1 and Q2 independently of one another are each hydrogen, alkyl of 1 to 8 carbon atoms, cyclohexyl, phenyl, halogen, hydroxy or amino. This rubber composition is increased in its loss factor, and is useful for tires such as tread parts. The resulting tires prepared from the rubber composition are improved in their gripping performance.
