What forum should wheel and tire questions be posted?
I know this is an old post but I have just started back looking into this topic. I did speak with a local parts department; however, the young lady did know. Are wasn't interested. I though that maybe someone here had swapped from steel wheels on a cab and chassis to the aluminum wheels.Have you called your nearest dealer about the fit? The parts department should be able to tell that.
Your post would be properly made in the OTHER TOPICS subforum. Go back to the main page and scroll down to it. There is a listing for tires, wheels, etc in that (3rd one down).
