I was wondering if there have been any issues with the 20-inch aluminum rims offered as an option on the Silverado and if so what they might be? Also any problems with the 18-inch rims? I'm looking to get a new truck soon and would prefer the aluminum 20's. I won't put any chrome plated aluminum rims on any of my vehicles again. If I can't get the 20's then I will look for the 18's. With the incentives. now looks to be a good time to replace the 95 S-10.
