The weak spots in the wire wheels will be where the spokes fit to the hub and rim. There will be flexing and any chrome plating that spans that gap will crack, creating crevices that are a nightmare for corrosion. Crevice attack. It is why body panels used to have a non hardening sealer to close them off. Even paint will suffer this eventually.
Stainless is your best bet, so you might consider selling yours and buying stainless. A bit of a money saver depending on what condition yours are in though.
