Rusted rim

Tomorrow will tell you that.

Good luck with it.

Disco.

As long as you got it as smooth as the proverbial babies bum you could have a show.
However, it seems to me that if it's pitted, I doubt you'll have much joy in the long run.

With the brand spankers steel rims on our camper, the first thing I did was run a bead of fisholene around the join between the inner and rim.

.....

But now that I think of it I didn't do the tyre/rim interface, so I guess I'm more or less in the same boat. Must check.

Des, I have HT Holden wheels on my tandem car-carrying trailer, and they kept going down.
I found the centre section of the wheel was heavy spot-welded to the rim in about 12 or 16 places (the centre material is about 3.5mm thick).
I also found that the spot welds had been "working" (flexing) under cornering forces, and the spot welds had cracked the rims in small semi-circles, where they'd been spot welded.
I installed tubes and the leaking stopped.
Many later rims have the centre and the rim welded in several places. This is a far better idea than spot-welding.

Good used, common model rims, are cheap, it's hardly worth the effort to try and repair rust damage. In the case of my car trailer, to properly cure the leakage/cracking problems, I'll have to replace the hubs and wheels with later Holden or Falcon hubs and wheels, as the HT pattern is pretty much obsolete now, and good HT wheels are very hard to find.

Also - be aware that there is often a difference in rim construction between car wheels and heavy commercial wheels on the common brands, such as Holden and Ford.

For example, the HQ-WB Holden rims on the 1-tonners have a much thicker centre section for heavier loading, than the standard rims fitted to the sedans and wagons of the era.
Similarly, Ford produce a heavier rim which is used on their Falcon utes and their high performance vehicles such as the police cars and the performance V8's.

Hey Des,
Time in the shed is never wasted!
I would have done the same, and if it didn't work, buy a new rim.
In years gone by, I brazed a rim centre when a small crack from offroad use caused a chronic leak. Was a bit tight on money 35 years ago!
