<p><P>PROBLEM TO BE SOLVED: To provide a pneumatic tire suitable for traveling in muddy place such as a field, and equipped with a lug showing sufficient traction from a case that inner pressure is low to a normal case. <P>SOLUTION: The pneumatic tire is equipped with the lug 100 extending in the direction intersecting the tire rotating direction D1. The lug 100 projects out of a surface of a tread to the outside in the tire diametrical direction, and has a center side lug portion 110 positioned close to a tread center portion, and a shoulder side lug portion 120 positioned close to a tread shoulder portion. A shoulder side disposing angle &alpha;<SB>s</SB>is different from a center side disposing angle &alpha;<SB>c</SB>. If a straight line passing through a tread center 112c at a center side end 112 and a tread center 122c at a shoulder side end 122 is set to be a lug center line 100CL, an inflection point P from the center side disposing angle &alpha;<SB>c</SB>to the shoulder side disposing angle &alpha;<SB>s</SB>is positioned close to the tire rotating direction D1 from the lug center line 100CL. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT</p> |
