In theory I would tend to agree with Sheldon's statement above. However on Tuesday I came up over a bit of a rise to discover a stretch of bike lane littered with multiple broken beer bottles -- there was a lot of jagged glass on the road and no way to avoid it. Too late to stop ... crunch .... crunch ... crunch!
The Vitoria Team Pro (with well over 500 "city" miles on it) on the front came through like a champ. The brand new "heavily armored" Armadillo something or other that I had just bought at the LBS on Monday was sliced up like a piece of baloney right through the tread and belt into the inner tube. Both tires were at proper pressure.
I guess all this proves nothing -- but I don't think I will buy any more heavily armored Armadillo whatevers.
Buy the way, I think Continental makes a very serviceable 27" tire. If I can find these I tend to buy them for my "vintage" rides.
