first experience was that it took quite some effort, time and a lot of swearing th get the new tire on a roadbike rim (i went with the 28c, had a 25c before on that rim and it looked like there is room left going even wider). once it was on it seemed to sit well and the first test arou d the block looked good annd felt comfortable at 80psi.during the first actual ride i experienced a loud pop at the end of a downhill stretch and the tire had come off the rim - resulting in a tube fatality. not sure about the reason for now - during higjer speed downhill nothing felt wrong, at the end of the downhill o had ro brake hard due to crossing traffic from both sides. still on rim brakes and the rims definitely felt pretty warm/hot. plus i had changed the tube along with the tire moving to tpu. that way it could also be the tube not happy with the heat even though unlikely.will give the setup another chance before deciding in which direction the rating should move.i found a few reviews here mentioning tires coming off the rim which would be a major concern for rider safety - especially if this happens at high speeds. the tire being really difficult to get in shape and on the rim after unfolding them is a first for me and hints they might be the issue.
