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?

I need to replace the rear tires on my 2007 C4s and it turns out the Michelin Pilot Super Sports are completely unavailable, with no ETA. Even if one makes allowance for the odd size and likely small demand, that is still pretty shocking. What alternative have you tried and what do you recommend? Car is a daily driver, street driven, I value quiet running (not that our cars are *that* quite, but would rather not add running noise).
I did my first track day in my 997.2 S, and am hooked. Next up is to avoid grinding down my street rubber, and move to DOT approved dry tires and wheels. I currently have 19" wheels on the car, but am thinking of going to "-1" or 18" wheels as there seem to be more tire options, and they are a bit less expensive. I've got the following questions:
1. What wheel widths should I be looking for?
2. What is the corresponding tire sizes?
3. What offset is 'right' and if right is different from 'acceptable' what's the range?
4. Any tire recommendations (folks at the track were raving about the Nittos)?
