W123 Bundts question - Page 2 - PeachParts Mercedes-Benz Forum

If you have a factory service manual (FSM) you can see loads of wheel and tyre information in chapters 40-100, 40-102, 40-104.

For example, skinny 15" rims (5 1/2J) were also fitted to W123s when delivered with a slightly higher suspension for countries with poor road surfaces (Chassis numbers 123.02, 123.03, 123.04, 123.1 and 123.2) and for the stretch limo versions of the W123 (Chassis numbers 123.028, 123.125 and 123.132) but I think most of these vehicles were fitted with steel 15" rims.

As for 15" Bundts you'll find that they were fitted to 107, 116, and 126 models with a 7J X 15 H2 25mm offset. Part number 126 400 22 02 - but there were probably more versions of the 15" Bundts (I only have a W123 FSM)

As far as I know, the 15"bundts were supplied from the factory only on 70's V-8 sedans like the 6.9. V-8 107's and V-8 126's came stock with 14 x 6.5" Bundts, at least in the US. But who knows what someone could order as an option.

Good info. The 15" Bundts fits similar generation MB's (107, 116, 1st gen 126 (maybe 2nd gen), and of course 123).

There are also aftermarket versions of the 15" Bundts made by Centra, Intra, Ronal, ATS and ARC-Alurad.

Among these aftermarket units, ARC and ATS look almost identical to the original Fuchs MB 15" Bundts.

I'd recommend having the tire side of the rims sprayed with several coats of an epoxy type paint from bead to bead. In fact, I'd do that on any cast wheel. It would resolve any possible issue of porosity. The exterior can be finished or left raw, whatever you like.

Nice tip but isn't an epoxy coat the spongiest most flexible type of paint out there? Please correct me if I'm wrong I'm no paint expert - but wouldn't it rub off quite quickly?

I was thinking about powder coating my wheels. How do you think powder coat compares with epoxy paint?

When the tires are mounted....its not even subject to the elements. Epoxy paints are some of the most durable ones out there. Actually overkill for this application....but if you have a compressor and spray gun or access to them....its cheaper and better to buy a pint of it than it is to get a few rattle cans of cheap garbage.

What you are doing is sealing small or microscopic pores that might be in the castings.
