I've searched and seen both 7.5/8.5 and 8/8.5. What's the real widths? The reason I ask is I just had some new tires installed and the installer scratched up 1 front and 1 rear rim. They say they will replace them with reconditioned rims, I just want to make sure they don't stick me with 2 fronts or 2 rears and maintain proper/similar wheel widths front and rear. Anything else I should watch out for like non OEM replacements? Any way to tell the difference? Thanks!

I believe the following is correct:

C55 RIM Specifications:
Diameter: 18"
Front Rim Width: 7.5"
Front Rim Offset: ET37
Rear Rim Width: 8.5"
Rear Rim Offset: ET30

Bolt pattern: 5 x 112

According to the Mercedes-AMG website the fronts are 7.5" width with ET30 offset; the rears are 8.5" width with ET34 offset.

Those are right specs as I have seen it on the back side of each of the wheels.

The front wheels are "one-offs" for the C55 to accomodate the wider track.

It seems pretty clear that the f/r WIDTH's are 7.5 and 8.5 respectively. But there is still confusion over the offets. My stealer says the front offset is ET37. Perhaps there is a difference between years or countries?

what are the weights again? I keep looking and can't find them. I should have weighed mine when they were off.
