I'm thinking of buying a set of used MB steel wheels from a wrecker to mount snow tires on. Well I went to every wrecker in town and believe it or not there's not a single W123 to be found. But there are several W114/115's and a couple of W116's in the yards. So I was wondering if these steel wheels will fit my car? Right now my car has the MB alloy wheels but I don't know if these are 14x6 or 14x6.5 since I can't find the owner's manual. From reading old reviews of w114/115's they all seem to have 14x5.5 steel wheels so I guess these are to small. I have an review of an '74 450SE and it says it uses 14x6.5 steel wheels. Somebody what to clear up this mess of wheel sizes. Thanks.
