Hey PorkDaddy,
239.00 sounds like a really good price. I didn't put a ton of miles on the Pirelli's as I also have a set of rims with Metzeler Karoo's on them for dual sport. Overall I found their sticky'ness to be as good or better then the OEM Bridgestones. Never had them in the rain. I liked the stock Bridgestones but they sure wear out fast. I may be putting my 17" rims with the Diablo Rosso's up for sale so I probably won't be able to comment on their life. Sorry I don't have more good info for you. I think overall they are a good choice. Not a lot of choices for street tires using OEM sizes and using radials which makes these a good alternatives to the Bridgestones.
