PURPOSE:To obtain the subject composition capable of providing studless tires excellent in gripping properties on frozen road surfaces and good in acceleration and braking performances, etc., by blending a specific rubber component with a silylating agent. CONSTITUTION:This composition is obtained by blending (A) 100 pts.wt. rubber component in which liquid polyisoprene having OH group or liquid polybutadiene having OH group or both account for 3-40wt.% of the rubber component with (B) 2-15 pts.wt. silylating agent. Furthermore, any one of a chlorosilane compound, an alkoxysilane compound and a silazane compound is preferably used as the component (B) and components other than (C) a vulcanizing agent and (D) an antioxidant are preferably basically kneaded at 130-170 deg.C and the components (C) and (D) are then preferably added to carry out the finish kneading. |
