Specifically, for both the 20" and 17" wheels used on the 4th Generation Laramie, including width (don't know what the width of the 17s is), offset, backspacing, and weight?! You'd think this would be widely available, but I'm having no luck finding it.

Thanks. Backspacing still not there, but you can get pretty close by taking 1/2 the wheel width and adding the offset. I assume that the figure following the wheel width is the offset.
