An automotive passenger vehicle full face wheel having a sheet metal disc-rim including a central bolt circle mounting portion, an intermediate portion extending generally radially outwardly therefrom and an outer peripheral portion surrounding the intermediate portion having an outboard tire bead retaining flange. The rim part includes a rim edge portion extending circumferentially continuously adjacent the rim outboard lead seat and permanently joined by a continuous weld to the disc-rim outer peripheral portion. In a first embodiment the disc-rim intermediate portion has an outboard-concave bowl shape with a radius of curvature ranging about 10.50 to about 11.00 inches. The bolt circle mounting portion has pad surfaces defining a wheel mounting plane and a frusto conical transition portion outboard divergent therefrom joined integrally to the bowl portion by an annular bend portion spaced axially from the mounting plane about 0.75 to 1.50 inches. In a second embodiment the disc-rim intermediate bowl portion is integrally joined to the outer peripheral portion at a bend junction radially spaced inwardly from the rim edge flange portion about 14.30 to 13.71 inches. The disc-rim bowl portion has a radius of curvature of about 10.50 to 11.00 inches and the wheel offset dimension is about 1.0 to 1.25 inches.
