Following up on my original post years later:
I recently, I bought a new set of tires for my 1995 GMC Jimmy SLT and thought I'd try a little experiment. Along with the tires I bought an OEM set of Chevy 4X4 alum. alloy wheels (I like the look of the Chevy OEM's better than the OEM GMC's). One of the things I noticed right away was how little of an offset the Chevy 4X4 OEM wheels had compared to the "Prime" alum. wheels that came on the truck when I purchased it in 1997. I would say that the "Prime" wheels where offset nearly 1-1/2". I had an alignment done after the installation of the new wheels and tires and took it out on the highway. It had a smooth ride through all speed ranges.
