well sure, my point was in contrast to the cavalier, "hey, i'll just grind these bits off because I don't know what purpose they serve and I just gotta save a few ounces".
And clearly I'll leave all such FEA matters up to you.
My intuition is that the ridge is there deliberately to spread load and act as a spine. without it you get heavy concentration of stress at the hoop/spoke interface. FWIW the automotive "standard" pothole (defined loosely) for wheel impacts is something like 3G up and 2-3G rearward.
