<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving run flat durability while maintaining tire weight. <P>SOLUTION: The pneumatic tire includes: a reinforcement rubber member provided at a tire width direction inner side of a carcass layer at a tire side, forming a crescent shaped cross section along the carcass layer, and having a JIS hardness (20°C) of 70-85 and a loss factor tanδ (60°C) of 0.10 or lower; and a side rubber member provided at a tire width direction outer side of the carcass layer at the tire side. At least a part of the side rubber member positioned at the tire radial direction inner side than the tire maximum width position includes rubber having physical properties so that the JIS hardness (20°C) is 70-85 and the loss factor tanδ (60°C) is 0.10 or lower. <P>COPYRIGHT: (C)2013,JPO&INPIT |
