All I have seen have been chromed/faux chrome plated aluminum wheels. The trouble spot then is at the edge of the plating. Could be as some have mentioned, a chemical reaction. Problem it creates is a tire you increasingly have to put air in because the plating coming off with damaged aluminum is right where plating ends - same place bead seats.Lots of Aluminum Wheels here and never seen a corroded one and I have family in the business...
Maybe it is snow/salt exposure?
Winter in the Bay Area is when it rains.
