Title: Indestructable tire!
Review: Jan thru april of 2012 I had 8 flats on my commute to work through the city. I got tired of changing tires and I bought these. Guess what? No flats from April to October! I have run over some broken glass on occasion and no flats. The tires are not that much heavier and I'm commuting, not racing anyway. These tires are expensive upfront but tubes at $4-$5 a pop will catch up with you sooner rather than later.
Is the review positive or negative?
