A tire suitable for a guide wheel position of a tractor comprises a tire tread, and the tire tread comprises a first tire shoulder pattern strip, a first pattern groove, a first middle pattern strip, a second pattern groove and a center pattern strip which are sequentially arranged in the circumferential direction. A second tire shoulder pattern strip, a fourth pattern groove, a second middle pattern strip and a third pattern groove are symmetrically arranged about the radial plane of the tire; the width of the central pattern strip is 15%-17% of the width of the tread, the width A of the first pattern groove and the fourth pattern groove is 4%-8% of the width of the tread, and the width B of the second pattern groove and the third pattern groove is 1%-3% of the width of the tread; the width of the first middle pattern strip and the second middle pattern strip is 16%-18% of the width of the tread; and the rest parts are first and second tire shoulder pattern strips. According to the invention, five pattern strips and four pattern grooves are adopted, and the purposes of increasing the mileage of the tire and reducing the rolling resistance and abnormal wear resistance of the tire are achieved by optimizing the shape and depth of the pattern grooves of the tire and the width of the pattern strips.
