Actually if you look at a ‘74 Charger sales brochure they refer to them a Magnum Road Wheels with a chrome trim ring available in 14” but interestingly enough it also shows that a 15” chrome Road Wheel was also available. FYI, I have never come across a Mopar factory equipped with a 15” chrome Magnum. It goes to show you that the guys writing the sales brochures didn’t talk to the guys writing the parts catalog.
Parts catalogues are mostly dry and naked facts, for many people unbearable. But then the marketing lets our brain spin around so we buy stuff we want but don't need.
Road Wheels? What does that actually mean? LOL...
I stay with Mopar's parts catalogue. The official binder. Mind the official parts catalogue is from 1974 (sales code W23). Other years, other marketing vocabulair and tricks to pursuade the emotional thinking human species. Nothing to agree or disagree on. Not seen the labeling Mag 500 in the 1969 catalogue. The same (bit smaller) wheels with trim rings were just called 'Chrome Wheels' (part no: 2944162, Belvedere and Coronet, 14"x5,5 not 14"x6 as in 1973-74). Nothing musculin or sexy in the name, as a trigger to develop any unleashed desire. I do not know about other years.
I am happy with my 14" Mag(num) 500 wheels
