Abstract
A pneumatic tire has an asymmetrical tread pattern. An outboard central main circumferential groove extends zigzag and is made up of alternate minor and major groove segments. The major groove segments incline at an angle of from 5 to 30 degrees with respect to the tire circumferential direction. An inboard central main circumferential groove is widest in main circumferential grooves. Outboard middle axial grooves are widest in axial grooves. The distance Li of the widthwise center line of the straight inboard central main circumferential groove from the tire equator is less than the distance Lo of the amplitude center line of the zigzag outboard central main circumferential groove from the tire equator.
