Hi, new to the forum and also new Fiat owner, found a fairly original, 1973 850 Spyder with 4300 miles. Had not been tagged since 1984. A local mechanic has it running, 3 of the 4 tires were Kelly Springfield, and of course all of the tires have dry rot. I did search the forum first, but did not see a lot of links. Just curious what tires you have used on your older Fiats? Only asking because I know there are manufactures for older American muscle cars that are "period correct" with the new tire technology. TIA.
