I won't buy SPecialized tires. I paid $40 for a Mondo S works. It was thrashed within 500 miles, misisng a chunk of rubber. i know others with similar stories, ther was one posted in the road forum just the other day with pics where rubber lifted off the tire.
Well, other than an Armadillo. I did 5000 miles on one last year with all sorts of terrain, trail, roads, mountains without a single flat!
Threads were starting to seriously show so I took it off, but not a single flat!
