The invention relates to a production method of hot rolled steel for an automobile tyre rim. The production method comprises the following steps: carrying out LF (Low Frequency) furnace external refining, slab continuous casting, heating by a stepped heating furnace, rolling of a hot tandem rolling unit, laminar cooling, rolling, inspecting and warehousing in sequence. Besides, the production method also comprises the following process treatment steps: before a heating technique of the stepped heating furnace is carried out, coating the surface of steel obtained by a slab continuous casting technique with a layer of coating material A; before a laminar cooling technique is carried out, coating the surface of steel obtained by rolling of the hot tandem rolling unit with a layer of coating material B. The production method disclosed by the invention is improved on the basis of an original production method, i.e., the surface of the steel obtained by the slab continuous casting technique is coated with the specific coating material A, and the heating technique of the stepped heating furnace is carried out; the surface of the steel obtained by rolling of the hot tandem rolling unit is coated with the specific coating material B and then the laminar cooling technique is carried out, so that the cracking phenomenon in the production process of the steel is avoided.
