Abstract
A tire includes a pair of sidewalls and a circumferential tread having a zigzag circumferential groove. The zigzag circumferential groove is defined by a groove bottom, a pair of groove walls, and a pair of groove edges defining an intersection between each groove wall and a top surface of the circumferential tread, wherein each of the groove edges smoothly widens and narrows along the groove. The circumferential tread has a first circumferential pitch with first and second circumferential pitch lengths. The first circumferential pitch includes a first zigzag circumferential groove segment and a second zigzag circumferential groove segment that form a first intersection angle. The second circumferential pitch includes a third zigzag circumferential groove segment and a fourth zigzag circumferential groove segment that form a second intersection angle different from the first intersection angle.
