I have four brand new Pirellis for sale, size 205/50 r17. I originally bought them for summer/track tires, and ended up getting new 18" instead. They were originally $220 each, but I figure they can make someone else happy.
They have not been mounted on wheels, and have been stored in my basement (read: climate controlled)
FYI, this is an extremely aggressive summer tire, and is really a street legal competition/slick. This tire is the Original equipment tire for the Ferrari Challenge Stradale, as well as the F430 Scuderia, to give you an idea of its performance capabilities.
I am asking $150 each plus shipping...
