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.

You measuring the rims themselves? or just the tire?
what rims are you talking about specifically?
what tool are you using to measure this?

You should have a sticker somewhere on your rim that says something like "559xNN",with NN the rim's width. Compare that to this chart to see what will fit:

I use 1.5 in slicks on MTB wheels made for any knobby tire. It works just fine. I don't see any reason why that wouldn't work for you too. Not sure what your bike shop is thinking.

That depends on the bike, many older mountain bikes came with 26x1.75" rims. I have an old Ross that has them. I wouldn't put a 1.5 inch tire on them and there is really no need or advantage.

Thanks everyone. The rim is a MTB rim as I purchased it some years ago for this same bike. I tried the 1.5" tire on the rim last night then tested on the bike trainer and had no problems after an hour and a bit of riding on the trainer. I will see how it goes over the next few days and can always switch back to the 1.95" tire if need be.

I doubted you had such a wide rim , were just calling the tire the rim.
seems confirmed .
Ross is just the brand they didn't make the rims , so still nobody measures anything.
I run 1.9" tires on my Snow Cat rims , they really are wide .. 45mm . or 1.5"
the tire takes on a straight sidewall D, shape. rather than a usual more round section.
Its running Studded tires, now..

Chances are good that the 1.75" rims are only 25mm across on the inside, so a 1.5" tire would be fine by the ETRTO guidelines. I wouldn't go any narrower, though.
