09 escalade rim question

[09escaladehybrid]

So my 09 Escalade (hybrid) started giving me a low tire pressure reading. After airing up the offender and keeping an eye on it, I confirmed that it's leaking. I checked the valve stem and core with dish soap but no bubbles so I took it to the local tire shop. The Michelin's have about 15k miles so they're in good shape. The tire guy showed me that the 22" chrome over aluminum rim was flaking off which keeps the bead from sealing. It's also been below zero for days so that doesn't help either. Rather than replace the 4 rims with aftermarket's made in Asia for $1,200, I'm wondering if I can just put tubes in the tires ($150). I've done this with other setups on trucks. Does anyone know if this will work on the Escalade? It almost seems too simple but thought I'd check for your thoughts. Thanks in advance.

I sometimes put tubes in low speed non dot tubeless tires if the rim has issues with rust and it's hard to get a replacement or the unit is due for scrap within a few years. it seems to work fine, just makes them kinda annoying to unmount.

does anyone even sell a 22in tube that would work in a low profile tire? you should use the correct size, if they are to big they have folds in them and over time the folds are where leaks start. other that that seems like balancing would be the only big concern.


but for me, you can't see the inside bead. if it was mine I'd just hit it with a wire brush attachment on something high speed and knock all the flaking chrome off. put the tires back on and go?
