I have a set of 20" Mich Dia's which came off my Cayenne Turbo. Size is 275/40/20. They are all in great shape with between 60-70% tread left. No nails or any damage just regular (even) wear. These are FREE. Come pick them up as i'm sick of looking at them. I will not ship- so please don't ask me about the rates as it's just too much of a pain. Tires located in Camarillo CA.
