<P>PROBLEM TO BE SOLVED: To provide a tire which combines excellent ride comfort with steering stability at high level. <P>SOLUTION: The tire 1 has a rectangularity Ri of a tread part 11 located on one side which is 10 to 20% smaller than a rectangularity Ro of the tread part 11 located on the another side. That is, the tire satisfies a relation of 0.8Ro<Ri<0.9Ro. The rectangularity is represented by following formula: Rectangularity (%)=L/W×100, wherein W denotes a length of a ground-contact shape of the tire in a tread width direction, and L denotes a length of the ground-contact shape in a tire circumferential direction, the ground-contact shape being formed by the tire when the tire is in ground-contact with a road surface when a normal inner pressure and a normal load specified by JATMA are loaded on the tire. Here, measurement positions are positions (Pi, Po) of 80% outside in a tread width direction from a tire equator plane CL at a maximum width position, where a length is largest in the tread width direction crossing the tire equator plane CL. <P>COPYRIGHT: (C)2013,JPO&INPIT |
