My Campys are 7's and 8's. However I bought an extra set of 7's and 8's (only to get the 8's) so I could mount 8's on the front of my car. It's taken me so long to get my new tires mounted because one of the 8's I bought was cracked. I sourced another wheel which a fellow member on this board generously donated to me, but it was corroded and pitted beyond being safe, and now I'm waiting for another wheel to arrive from Texas from another generous benefactor on this board (Thanks guys!). Hopefully I'll finish restoring the wheels next week so I can get my tires mounted.
Anyway, here are a list of tires I found a year ago when I began investigating tire options for my stock Campy wheels:
