<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of exhibiting excellent driving stability even when a low-exothermic and low-hardness rubber composition is used for a cap tread compound. <P>SOLUTION: In the pneumatic tire, a pair of circumferential grooves 11 elongated in the circumferential direction of the tire is provided on both sides of a tire equator line CL of a tread part 1; a first land part 21 is demarcated between the pair of circumferential grooves 11; and the land part 21 is demarcated on the outside of the pair of circumferential grooves 11. A tread profile, in which a position of the tire equator line CL of the land part 21 is a maximum outside diameter part of the tire, is configured in a state in which the tire is assembled to a normal rim and in which internal pressure is adjusted to normal internal pressure, and a groove wall on the tire-width-direction inside of each of the circumferential grooves 11 arranged on both the sides of the land part 21 is set higher than a groove wall on the tire-width-direction outside thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
