A ratio by weight of the total amount of the reinforcing filler to that of the plasticizing agent is less than 4.50. The total amount of the reinforcing filler and the crumb rubber is more than 30 phr and less than 70 phr. A ratio by weight of the total amount of the crumb rubber to that of the reinforcing filler is more than 0.20 and less than 2.50.
