The invention relates to an all-season tire with symmetrical patterns. A tread central pattern block is an irregular polygon with at least two acute angles; at least two acute angle directions of the central pattern block are arrayed along the circumference of the tread; two side pattern blocks adjacent to the central pattern block are irregular polygons with at least one acute angle; at least one acute angle of each irregular polygon is arrayed along the circumference of the tread; main water drain grooves are formed in the adjacent parts of the two side pattern blocks and the central patter block; each side pattern block and the adjacent tire shoulder patter block form a main water drain groove; the main water drain groove is a sipe formed in the adjacent part between two adjacent pattern blocks; the main water drain groove is unparallel to the equator line of the tire; and a certain included angle is formed between the tire equator and the broken line formed by surrounding along the circumference of the tire crown in a non-continuous manner. Not only is the excellent drainage performance during raining guaranteed, but also the handling stability and steering stability on dry and wet road surfaces and the comfort during high speed driving are guaranteed.
