Pneumatic tire

A pneumatic tire comprising

• a tread portion bound with an intended tire rotational direction, and provided with a plurality of main grooves extending continuously in a tire circumferential direction,
• wherein the intended tire rotation direction is indicated in a sidewall portion of the tire,
• wherein the main grooves include a crown main groove, a pair of middle main grooves extending on both sides of the crown main groove, and a pair of shoulder main grooves extending on both outer sides of the middle main grooves, wherein
• each of the middle main grooves has, in its top view, a zigzag configuration in which first oblique segments and second oblique segments are alternately arranged, wherein
• the first oblique segments inclined outwardly in the tire axial direction toward the opposite direction to the intended tire rotational direction, and
• the second oblique segments inclined oppositely to the first oblique segments, and having a circumferential length less than the first oblique segments,
• wherein middle land regions defined between the middle main grooves and the shoulder main grooves are provided with a plurality of middle transverse grooves connecting between the middle main grooves and the shoulder main grooves, wherein
• the middle transverse grooves inclined to the same direction as the first oblique segments, or alternatively, extending in parallel with the tire axial direction,
• each of the middle transverse grooves has a depth less than the middle main grooves, and
• the axially inner end of each of the middle transverse grooves is connected to one of the second oblique segments so as to include at least an axially outwardly protruding outside corner portion of the middle main groove, and
• wherein grooves disposed in the tread portion and extending continuously in the tire circumferential direction are said crown main groove which is a straight groove, said pair of middle main grooves which are said zigzag grooves, and said pair of shoulder main grooves which are straight grooves.
