The invention discloses a 540 LF steel strip for 540 Mpa-grade automobile spokes and a production method of the steel strip. The steel strip comprises the following chemical components of, in percentage by mass, 0.08-0.12% of C, 0.04-0.10 of Si, 1.3-1.4% of Mn, less than or equal to 0.012% of P, less than or equal to 0.004% of S, 0.020-0.050% of Als, 0.02-0.04% of Nb, 0.01-0.03% of Ti, and the balance Fe and unavoidable impurities. The production method comprises the following processes of continuous casting, heating, rolling, cooling and reeling, wherein the cooling process adopts a laminar cooling process. The tensile strength of a prepared steel plate can reach 540 Mpa or higher, the problem that the mechanical property cannot meet the standard requirement during trial production of steel for the 540 Mpa grade spokes in the prior art is solved, the microstructure and the mechanical property anisotropy are greatly improved, the steel strip is stable in rolling performance, uniform incrystal grains and small in anisotropy, and the uniformity of the spokes furing spinning deformation is improved.
