What's the biggest summer radial tire size that I can install on a 15"
rim. The OEM size is 225/60.

1) The diameter of any tire, if it's the same (+/- 4%) will work.

So, you can go to a 55 or 50 or if you're really nits, 45 series tire.

2) The width of the rim will dictate how wide you can go.

You could go wider but it starts getting silly. I wouldn't go more than 235.

Once more with feeling:

Why not ring up BMW in Germany and ask for a recommendation?

They will probably suggest 225/60, which I suspect might just be why they
fitted it in first place.
