i disagree, the PR series is a touring tire. not a performace/ hyper-sport tire. thats why i run the PP3's for street. loads of millage. still on my first set which has lasted to longer than 2-3 sets of Q3's lasted me and they still look almost new.
if you ride at decent speeds/ maximum lean angle than i wouldnt trust a touring tire. if your out for casual jaunts through the backroads than PR's are great. but if your doing any "spirited" riding than PP's are a great choice.
tires are ALWAYS a trade off between grip and longevity. some tire manufactures are better than others with using carcass compounds, construction techniques and tire profile to enhance the amount of grip and "feel" while also optimizing millage. but regardless the more grip, the less millage.
whats important for street riding is that you really cant get speeds/lean angles (safely and sanely) to justify hyper-sport tires.
as for the track i wouldnt use anything other than a Q2/3 or equivalent as speeds, lean angles, and braking are all much more aggressive.
just my 2 cents tho
