The wheels on the show car at Kansas City were polished and they looked very nice!PAS22 said:Since GM has indicated an availability problem with chrome rims until Sept. does anyone who has been to the shows know if the stock rims are polished aluminum (or aluminium if you prefer) or painted????
My guess is standard wheels are aluminum, but not polished or chromed. Just coated, whether painted or not. This type wheel is subject to flaking and degradation when exposed to 1. salt-laden air in north in winter, or coast in summer 2. high pressure car wash.PAS22 said:So your thinking painted rims are stock?
Salt can be very bad for chrome, but it generally shows itself on cheap chrome. GM's factory chrome wheels all seem to hold up amazingly well in the north. Much better than clearcoated brushed aluminum wheels do. The clearcoated brushed aluminum wheels will begin to corrode under the clearcoat after just one or two winters, while the chrome tends to still look good for a number of years. GM apparently just spends the money on chrome to let it last, since I have seen aftermarket chrome rims that are trash after one or two winters too.Audio Imagez said:Are you sure about that? I thought that road salt stains and eats up chrome. I've never had problem with aluminum rims.
Im not all about the weight conservation like that or anything, But that does sound like a lot of chrome weightsolsticeman said:Go for polished aluminum.
I heard from a guy who used to work for a wheel company that chroming an aluminum wheel adds 1 to 1 1/2 lbs. PER WHEEL.
Gotta save that weight!!!:lol:
