If these are the factory Dunlops (which I think they are), I've got two in my garage with at least 70% - 80% tread left. I just replaced all four tires with Michelin PS2's. These tires are in great shape, and I would sell them for a song, if you don't mind paying shipping.
The 8080E's are the OEM tires. Tirerack sells them for $210 a piece which is better than anywhere else that I have found. My local NTB matched that price because they claim that their parent company supplies tirerack with their tires. Thus, the shipping was free, but I had to pay the tax which was a little more than what the shipping would cost.
