-i live in colorado springs, co.
-i ride about 8 miles round trip to work, which is about 40 percent on bike paths, the rest on streets. i can put way more miles on in a week, depending on my after work/weekend riding... and which bikes i choose to ride.
-i skip some, but never really skid. i don't ride with brakes either.
-my longest lasting, best flat resisting, fastest, grippiest tires are vredestein fortezza's. they might be so effective against flats because i run them at 130 to 140 psi. they are by far the best tire i have used.
i also have some continental attack/force tires, which have been great so far. these tires feel like tubulars, are light, roll fast, grip well, but seem easier to skip/skid with. i run these at 110 to 120 psi. they seem to have softer sidewalls, so i imagine low pressure could make them more prone to pinch flats.
