damaged rim

[mojobaby]

While doing restoration work to one of my tyre rims, I discovered a pea-sized hole next to the hole where the valve comes through, caused by rust.
The rim previously had an innertube.

My first thoughts were to weld the hole closed, but the tyre supplier said that for safety reasons it's "forbidden". Is this true?

In the meantime, I've managed to source another second hand rim for 20Euro which I'll be collecting tomorrow

As secondhand wheels are widely and cheaply available, don't think about it-buy a good one.
It's not dangerous to weld it around the valve hole (if done by a professional, of course), but a) the metal around may be too thin (eaten by the corrosion) so a large area will have to be built up, b) after you complete the repair, you will end with a heavy spot that will make the wheel hard to balance properly, and may need to be machined on a special lathe, c) more than likely. there will be other rusted places on the wheel d) if you add up the cost of repairing all of these properly, it can be equal to that of three or four secondhand wheels.

To stop this happening again, fit tubeless tyres.

Thanks for the advice Angel.

I went to a scrapyard and found a rim for 10Euros. I had them take the tyre off before I bought it and once again there was an inner tube fitted. There was quite a bit of rust once again but its fixable and far better than my one.

I think when an inner tube is fitted, water gets in the hole in the rim where the valve sticks out and causes the rust. Will definitely fit a tubeless tyre to prevent this happening again.

So here's is the second hand rim, with the rust removed, sprayed with a primer and top coat and fitted with a new tubeless Kleber 145/80 tyre.
