A mold (10) particularly for road vehicle wheels, of the type comprising a lower mold part (11), an upper mold part (13) and perimetric mold parts that form an impression (15) to be filled with molten material, and comprising a distribution unit (16) that is arranged below the lower mold part (11) and is meant to be connected to at least one riser tube (17), which is shaped so as to form one or more slots (21) shaped like a circular arc for injecting the molten material into the impression (15), the slots being arranged, when the mold is closed, at the outer front edge of the impression. The one or more slots are distributed circumferentially so as to allow a balanced injection with respect to the center of the impression (15).
