Have an extra set of 13” Dunlop’s for a Formula Ford for sale. Sorry for the title, I had 2 sets and 1 are Dunlop’s. They came with the car I bought to restore. I don’t know any history. They look like they have well over 1/2 tread. They look in good shape and don’t have any cracking or blemishes. I can help with any questions. Not sure what they are worth. Looking at other ads, seems $350 might be a good spot to start. Open to offers. Tires located in WI. Will be at Road America in May, July and Sept, if that interests any one. Thanks for looking.
