I bought a set of 27x1 1/4 Paselas for my Peugeot PH10, to find out that they are really too big. I have read over and over on the undersizing of tires back in the 70s and 80s, old Michelin 1 1/4 came off it with plenty of room, and was just curious as to how current tires compare to one another in that regard. Would I be better to drop down to a 1 1/8 or 1 inch Pasela, or try a different brand? For clarity, the tire is both too tall (I have to deflate it a bit and use some force to get the back tire in the frame), and too wide (there is little room between the tire and the frame, so that any decent bump that could wiggle the back tire the slightest gave me a rub). I've got other options to put the tires on, so I'm not worried that these will go to waste, just need to find something that fits a bit better for this bike.
