PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving steering stability performance of the tire. SOLUTION: The pneumatic tire 1 has three circumferential main grooves 61, 62 extending in a tire circumferential direction on a tread surface. Further, in the pneumatic tire 1, a tread part is divided to a first tread area and a second tread area making a tire equator surface CL as a border. At this time, the single circumferential main groove 62 is arranged at the first tread area, and the remained two circumferential main grooves 61, 61 are arranged at the second tread area. Thereby, an asymmetric tread pattern is formed. Further, a symmetrical profile making a tire equator surface CL as a symmetrical axis is formed. COPYRIGHT: (C)2009,JPO&INPIT |
