Anyone tried the IRC GP-110 tires? These look like a good fit for my kind of riding, but if anyone has any gripes about them I'm all ears. I'm on pavement more than dirt, but I want good grip in the dirt. Currently running the d606's that came on it. No real complaints about them, but I could use a more streetable tire. If the dirt ride is too much of a trade off I might stick with the 606's.
