I'm with Red. I keep my tires at 120 and I have had 2 flats in 10 years. Generally, the roads here are OK; no chip seal. I do feel the bumps, but, to me, it's part of riding. I also ride Contis, and I've never seen anything about 120 being "dangerous." My DH has different Contis that are actually rated up to 135, which is what he uses.
