Disclosed herein are tread rubber compositions containing a specified polyurethane, tires containing a tread made from the rubber compositions, and related methods of improving the wet and dry traction of a tire tread by using the polyurethane-containing rubber compositions. The polyurethane includes a saturated hydroxy-functionalized polydiene segment as diol.

    L'invention concerne des compositions de caoutchouc de bande de roulement contenant un polyuréthane spécifié, des pneus contenant une bande de roulement fabriquée à partir des compositions de caoutchouc, et des procédés associés d'amélioration de la traction humide et sèche d'une bande de roulement de pneu à l'aide des compositions de caoutchouc contenant du polyuréthane. Le polyuréthane comprend un segment polydiène fonctionnalisé hydroxy saturé en tant que diol.
