No complaints here. I've been riding 27 x 1-1/4 Pasela tires on my commuter for years. Most of my riding is on pavement, but I don't shy away from trails and gravel. This is a backway home I typically take around once per week. Yes, the sidewalls do feel thin, but I have yet to tear through a casing and I rarely get flats. I ride this bike almost every workday, heavily loaded with school papers, clothes, computer, lunch, plus my ~210-pound mass. Tires at about 60 psi, and I change tires when I see threads (if I notice).
