The theme for my truck was what it should have looked like from the factory. So, I do not want tons of nifty and expensive aftermarket components on it, which is why I am running chrome 16" Denali rims. They look really good and give a good gripe with the Cooper rubber when I go off-road maybe once or twice a month. But I really want to full out that wheel well, and need to know what are the biggest stock - e.g., General Motors Corporation or Chevrolet - rims I can fit on this application. Since it is not electronic, what would I have to do, if anything, to recalibrate the transmission once I do?
