Abstract
A pneumatic tire is provided with a tread having a shoulder portion isolated by a main groove, and a slit formed on the shoulder portion, wherein a first tapered portion is formed on a side wall of the slit which comes into contact with the ground first when the tire is rotating, and a second tapered portion is formed on the side wall of the slit which comes into contact with the ground later, an end of the first tapered portion on the main groove side is located at a position closer to the main groove than the end of the second tapered portion on the main groove side, and the second tapered portion is formed so that a width on an opening end of the slit opening at a contact surface is wider than the width of the portion where the second tapered portion is not formed.
