My old 32c Schwalbe Marathon's crapped out on me on the last day of my tour. The tire quickly lost pressure, so I walked it the remainder of the ride in San Francisco to a friend's house. There I fixed it, so I could ride it to a BART station...only 7 miles where I'd catch a private shuttle home. Another flat. Jesus....on closer inspection, I realized the sidewall had been blown out. I thought this might have been a manufacturing defect. I rode my old 25c Armadillo's to the LBS and asked them and they said no, that I must have run something over to cut the sidewall and that the tire was essentially dead. What a disappointment, only 2,000 miles in and the tire is done. I got them because I heard they were among the best. Maybe it was a fluke but I miss riding fatter tires. The Armadillo's ride is simply jarring. =/

I believe they're rated for 115-125psi. I have them at 100 now. Is that as comfortable as they get or can I go lower safely?
