I have a set of 235/40ZR17 Potenza RE-01R tires for sell. The set has one full season of autox (about 12 events) on them, plus about 500 miles of highway use. I also used them at one track day at Summit Point last year, but it rained all day, & I only ran 3 of the 4 sessions that day.

They are still in very good shape, and have plenty of tread left. They were bagged and put in storage for the winter. These are now going for $178.00 per tire new. Asking $500 for the set.
