http://www.diablo.getpirelli.com/ Pirelli is doing to their Diablo Corsa III intro as they did with their Diablo Strada intro earlier this year. You buy a rear tire from a Parts Unlimited dealership and go to the above link to fill out the claim sheet, print it out and send it to Pirelli with the original rear tire receipt. Pirelli charges $25 shipping and you get the front tire. I did this deal with the Diablo Strada and it saved me about $70 bucks. The front would have costed me around 90 from my favorite cycle shop.
