I have an old front race compound Michellin Pilot that Ive had sitting in storage for about 5-6 yrs. Is the tire still good? It has about 90% center and 60% far edges. They were race takeoffs I bought but never used the front tire. Its in good shape just feels dry of its tackyniss. I currently have a D208, not gp, and i need something with a little more confidence.
