pirelli corsa tires on 2004 challenge stradale!!!!!!

With 4000 miles on my stradale and tracked for the first time at Summit point at FCA National Meet Wash. D.C. Ferrari dealership was kind enough to point out innumerable "cracks" at the interface of the tread and the sidewall of all 4 tires. They told me of another customer with the pirelli corsa made only for the 360 challenge stradale with the same problem!!! I returnede to NY and Inquired at Ferrari of L.I. where I bought the car and they agreed that the car was unsafe!!!! I was told that they had a customer in Boston With the same problem!!
I called Pirelli customter support and spoke with a supervisoe and they were very, very understanding!!!! They will replace the tires on a prorated basis, based on tread life, and send new tires...the only new 19' tires are the ROSSO made for the ferrari 430., by Pirelli.
Please check your pirelli corsa tires on the 360 challenge stradale...it is a dangerous condition readily rectified by Pirelli!!!!
Anyone else with the same problem???
