1.5 inch tire on a 1.75 inch rim?
Looking to get back into full time commuting once the Orthopedic Surgeon finds out what is wrong with my knees. In the meantime and now that our local wet rainy winter is on the way, I have purchased a bike trainer to do some light indoor exercise.
My commuter is a MTB with a 26 x 1.75 inch rim on the back with a 1.95 inch slick tire. For riding my bike on the trainer, can I mount a 1.5 inch tire on that 1.75 inch rim? I asked at the local bike shop and was told no and that could only use a 1.75 or 1.95 tire on the rim.
Thanks in advance.
