I have two sets of the take off Pirelli slicks in 305/680/18 size. One set was never used. The other set has one 20 minute track session last week. They both have a ton of life left. I get my tires from John Berget in Wisconsin and he has never let me down. I really don't want to ship them and if you are relatively close to Philly I can meet you half way. $450 for the unused set and $400 for the used.
