3 of the 4 wheels on my megane RS are leaking air, approx 10 PSI a week. I think its due to corrosion, i've had all the tyres changed and checked the valves etc. Is this the sort of thing a full wheel refurb would actually solve or is it cheaper/easier to get some new wheels?
A full refurb would remove all corrosion and be as good a new set of rims.
Assuming they're not cracked or buckled that is. That said, a wheel refurb place should be able to straight and/or fix any issues like that and have them back to as new anyway.
