  1. Terrific, thank you. I only received the paper owner's manual with the car and wheel specs aren't included in that. I did, however, find the online manual and the wheels spec. it looks like there is very little offset difference between the two wheels; the 21" I have now with 50mm offset and the 18' wheels I'm looking with an offset of 53mm. Although running it through a calculator, it appears the 18" wheel face will sit inboard 28mm. So, if I want to maintain the somewhat flush look that I currently have with the 21" wheels, I'll need spaces?
  2. If my interwebbing is at all correct, there seems to be some differences between the 955/7 and the 958 wheels. I know they are interchangeable between vehicles, but I suspect there's some difference between the backspacing and offsets. I'm trying to get some some proper and semi-aggressive AT tires fitting to my CD. While I know the OEM 255/55-18 tires will fit with no issues, I'm wondering if I can't get a slightly taller and/or wider tire on my rig. Having access to OEM wheel specs should help me in that quest. Can you point me to a resource for OEM wheels specs? Specifically, the 18 inch wheels? Thanks
