Wheel / tire question

[wvstar]

I have found a set of factory reproduction grand sport wheels in 18x9.5 (57 offset) and 19x10 (56 offset) that are 'supposedly' the correct offset that will fit on the C5. Can someone verify these offsets will be correct? Also, would the following tire sizes be about right: 245x40x18 (front) and 285x35x19 (rear)?

Thanks!

I just installed a set of C6 Z51 (precursor to GS) OEM wheels and tires on A C5 and they fit without rubbing anywhere.

Thanks! I believe those wheels have a 79 offset on the rear (19"). If they don't rub...the 56's should be a no-brainer. I believe the tire sizes I quoted above were the stock size for the C6...is that the rubber your wheels have mounted?
