<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire having high wet performance and capable of reducing noises generated. <P>SOLUTION: A lug groove located in the tire surface in a tire peripheral direction includes a first groove wall face and a second groove wall face shaped to be changed relative to a first reference line with one cycle or more in a block width from a main groove to the other main groove or a tire grounding region. When the first groove wall face and the second groove wall face are projected from a connection part to the main groove toward the end of the other main groove or the tire grounding region in a direction parallel to the first reference line and a second reference line, at least one of the first groove wall face and the second groove wall face is projected all over, and P<SB POS="POST">min</SB><P<P<SB POS="POST">max</SB>and 0<P<SB POS="POST">min</SB>are established where P is the distance between the first reference line and the second reference line, P<SB POS="POST">max</SB>is the maximum width between the first groove wall face and the second groove wall face, and P<SB POS="POST">min</SB>is the minimum width between the first groove wall face and the second groove wall face. <P>COPYRIGHT: (C)2012,JPO&INPIT |
