1. A method of producing a vehicle wheel from a light metal material comprising introducing a light metal material in liquid form into a mold cavity of a casting mold via a gate region adjoining the mold cavity,
wherein the vehicle wheel is produced using pressurized casting,
wherein in areas in which the vehicle wheel has a smaller cross-section, the casting mold is tempered to higher temperatures, and in areas in which the vehicle wheel has a larger cross-section, the casting mold is tempered to lower temperatures,
wherein the light metal material is in a liquid state and is introduced into the mold cavity at a casting piston speed of more than 5 m/s and a pressure of less than or equal to 100 bar, and
wherein a ratio or modulus between the smallest cross-sectional area of the gate region and the volume of the mold cavity is at least 0.6 mm2/cm3, and,
wherein the wall thickness of the vehicle wheel that is produced is less than or equal to 1 mm in at least some areas.
