<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of reducing rolling resistance without damaging wear resistance, driveability, and puncture resistance. <P>SOLUTION: When the end part in the tire width direction of the shortest belt layer of the belt layer having the shortest length in the tire width direction is made to be the point B in the section including the rotating axis center, the length of the line segment extending parallel to a tire equator line from the point B to the tread surface is shorter than the length from the shortest belt layer to the tread surface in the tire equator line. The angleθ1 wherein the cord composing the longest belt layer of the belt layer having the longest length in the tire width direction is the acute angle inclined relative to the tire equator line is larger than the angleθ2 wherein the cord composing the shortest belt layer is the acute angle inclined relative to the tire equator line. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
