I couldn't post for free in the FF or Vintage section so they are here.
I have a set of 4 Avon Formula Ford vintage treaded tires. I bought them used, don't know the age. I put 21 heat cycles on them but I don't know about the PO. I ran them two weekends last year (Gingerman and Indy) and they were great.
You can pick them up at my house in Indianapolis, or I can bring them to my race weekends (Gingerman, Blackhawk, M-O, Indy, Rd America) until they are gone. If you are considering running vintage for the first time (like I was recently) you go to the front of the line.
