Hi all

As stupid as it sounds, I just can't get some new tires on to these rims I've got. The rim has a 17mm internal width which I gather should be OK with 26x1.5" tires. But when I try and seat the tire on to the rim at one side, I notice the tire rolling off at the other side, as if the beads aren't 'clinching' the rim. I've tried spraying soapy water on the tire and rim as well as baby powder on the tube, but no luck.

So I'm thinking maybe this is a rim for tubeless tires? I honestly don't know the difference (I've tried searching on this site and Google but to no avail). How can you actually tell the difference?

I've attached pics of the rim, but I appreciate they might not be that useful.

Any help as always appreciated.

Thanks!

Those are not tubeless ready rims. They could probably be converted to tubeless with a Stan's Notubes conversion kit, as can most mountain bike rims, but that's for running mountain bike tires at low pressure, not what you're after.` So the answer to your question is no, your problems are not being caused by any sort of tubeless/tube incompatibility. Actually, even if they were tubeless ready rims, you'd still be able to mount a tire and tube as you would with a conventional rim.

Over-inflate the tire. This will seat the tire. Extra soapy water should help but you need pressure. I usually need to take them to 80 psi or more.

You need to be real wary of tires labeled as 26"-something, as there's something like half a dozen incompatible standards using 26" in the name.
My guess is that you've picked up the wrong kind of 26" tire for your rim.

Stick with the millimeters if you have a choice.
