Winter wheel, steel vs alloy in salt

My two experiences running alloy wheels in a salty winter environment, led to corrosion causing leaks at the bead. On steel rims I’ve never had this issue.

For those running alloy wheels on salty winter roads, is there a particular type of wheel that can withstand this environment or are you experiencing the same problem
Thanks

idk if it helps but wax rims inside/outside when rotating your tires....

I've used the same cheap ($125 CAD ea) 17" alloy wheels for 2 full winters on my Mk7. And the wheels look exactly like when I bought them. I don't do anything special to them for cleaning or treating them. Also no leaks - just lose a few PSI from being stored in the summers, which is pretty normal.

I didn't buy them from this store, but these are the wheels I got (in 5x112 of course) with Conti WinterContact Si.

My old car with steels for winter, the wheels all had rust patches on them. YMMV (obviously).

Nice wheels
The issue is only between the wheel and tire beads. Oxidation allowing air to escape
