Indestructibility...: better corrosion resistance than chromed steel or aluminum alloy, and higher strength than aluminum alloy.
The Peugeot rims I've seen are dimpled, rather than serrated. Dimpling is a clever way to retain water rather than let it drain away.
I'd much rather replace my brake pads regularly (wear item) than, e.g. alloy rims, due to braking wear, or warping. That's just me... I'm not trying to convince you that my way is right for you; but if my info helps others, that would please me.
