I have three (3) Michelin tires that have about 500 miles on them. Two (2) are 225/40 ZR18 selling for $280, and one (1) is a 285/30 ZR18 selling for $200.  This is 1/2 what the cost would be new.  

I am located here on the Cape and can arrange delivery out here.  Please let me know if anyone is interested.
