Factory wheel sizing

[Babaganoosh]

I'm looking for either the 15's or 16's. I need to know the exact measurements width, backspacing and or offset.

I have found to many threads saying this will work and do this but I want to know what these came off the line with.


~Edit~

Found looking at brochures the 15's are 6 inch width and the 16's are 6.5 inch width.
Now to find the back spacing or offsets.

For the half tons, there were 15x6,7, and 8 too. Depends on the year and wheel, all were about neutral offset. I think all the 8-lug wheels were indeed 6.5 wide.

2wd was another story.
