Abstract: The present invention discloses a tire tread pattern provided with an anti-stone structure. The tread pattern is composed of an annular groove that is continuous along the circumferential direction and a pattern block, the annular groove is defined by a discontinuous first chamfered edge, a first polygonal surface parallel to the tread is arranged at a portion in the annular groove that is concave relative to the first chamfered edge, a second chamfered edge and a third chamfered edge of the first polygonal surface separately extend along the groove bottom direction to form two second polygonal surfaces, the two second polygonal surfaces and the first polygonal surface share a vertex S; and a groove bottom vein of the annular groove is zigzag along the circumferential direction.
