You'll only have one guaranty the paint will come off. You could take them off, remove the Tyres have them grit blasted, then 2 Packed or powder coated. Prolly stay on fairly well then but that is quite a hassle to have- let me guess. Black rims right.
^ just like that. They give a harder finish, both fairly chip-resistant but not impervious to scratching etc.
You could also try using plasti-dip (I think it's called that). It will resist chipping a little because it's flexible, but if it starts to peel it'll come away just as easily as paint (if not easier).
Whichever way you go, try to coat the wheel as evenly as you can, to avoid having to rebalance the wheels.
Plasti dip is ok because it can be removed, but I’ve found it seems to attract dust and is harder to clean off. My brother did his wheels with plasti dip and after an around Aus trip because of all the dust.
Alternative might be buying a set already painted or powder coated and selling your current ones. I see them fairly regularly on online trading sites.
