The invention provides wheel steel with high wear resistance and crack resistance and a wheel production method. The wheel steel comprises the following components: 0.58 to 0.75 percent of C, 0.55 to 1.0 percent of Si, 0.70 to 1.0 percent of Mn, 0.15 to 0.35 percent of Cr, 0.03 to 0.06 percent of V, 0.005 to 0.010 percent of P, 0.006 to 0.015 percent of S, less than or equal to 7ppm of T.O, less than or equal to 1.5 ppm of [H], 60 to 100ppm of N and the balance of Fe and inevitable impurity elements. Compared with the prior art, through component design and design of a matched wheel production process and a heat treatment process, the tensile strength (Rm) of the produced rim is larger than or equal to 1200 MPa, the yield strength is larger than or equal to 800 MPa, the rim abrasion limit brinell hardness is larger than or equal to 321 HBW, and the wheel has good high abrasion resistance and crack resistance.
