Salt on rims
Probably not. It's a factory part and wty replacement if they got bad unreasonably soon. In the winter I get a wash (with wheel and underbody spray) every time I fill up. But the salt will take it's toll over time, probably with small pits, etc.
It's the aftermarket rim finishes the worry me. I want to move up to 17" but I also need to find a brand that will keep looking good after a couple years on a daily driver.
