PURPOSE: A tire with improved grounding performance is provided to increase stability and controllability by extending a side part of the tire in a width direction with a reinforcement member according to the rise of the tire temperature and by improving the flatness of tread. CONSTITUTION: A tire (1) with improved grounding performance comprises a reinforcement member (2). The reinforcement member protrudes a side part (1a) of the tire in a width direction (111) of tread (11) according to the temperature rise of the tire in high-speed driving. The reinforcement member is bimetal in which metal plates with different heat expansion rates are overlapped. The reinforcement member is connected to carcass along a carcass edge. |
