Accidently glued the tire to the rim...

I got a flat tire on my mountain bike and it is impossible to pop the tire off the rim. I resorted to cutting the tire and inner-tube off and tire bead is still glued onto the rim. I certainly didn't intentionally glue the tire on, it is just a regular tire and I'm not running tubeless.

Barring a vindictive ex-girlfriend, the only thing I can think of that might have caused this glueing phenomena is that I couldn't get the bead to sit right so I followed a hint I read here about using windex to lubricate the bead and let it pop the bead into place. It took a bit of windex, but eventually the tire seated itself quite nicely.

I left part of the rim sitting in soapy water today but it still won't budge. Any ideas?

Try come orange based cleaner and a razorblade and carefully remove the tire bead. How old is your tire? I have sometimes changed tires for friends who have had the same tire on the rim for years and the bead has "glued" itself to the rim.

See if you can get some acetone from the hardware store. If that fails, "Goo-Gone" may do the trick.

I've never had to deal with this. Maybe the heat from a hairdryer would loosen the bond? If the wheel is steel, a wirewheel attachment on a drill might scour it off. Aluminum is probably too soft for that method.

If the wheel was a really tight fit, sounds like it was, it may just be hung on the bead lip. SOmetimes the tire/wheel bead mismatch is enough that a tire lever will not unseat it, you may need to use something narrow like a (horrors) screwdriver to get between the rim and the tire to force it off. Even if you have had some bonding action, this would work to get it off.

The acetone is a good suggestion... I'll give that a shot.

I'm still confused as to what caused the tube to glue itself to the rim. Both the rim and and tire claimed that they are tubeless compatible, could the windex have reacted with the tire?

The tire and rim are tubeless? That means you have an air tight fit. The key being tight. Windex does not react with alluminum or rubber, it is not glued on, the tire is firmly seated to the bead.

If that is the case, I'm super impressed.

I have cut the tire tread completely off the rim/bead. Then yanked, pulled, and pried on the two strips of tire trying to get it to separate from the rim.

If this is how tubeless tires are supposed to be, I want nothing to do with them...

Ok, I'm impressed.

After taking a razor blade to one side and cutting the tire away from the wire bead, I got a close look at it and I could move it with a screw driver. So as delicately as I could, I used a screw driver to pry the bead way from the side of the rim and it came off exactly like normal.

So is this how tight tubeless tires normally are? If so, how do you remove it without damaging the rim? (I was careful but there is a small mark from the screwdriver...)

The "trick" with tubeless rims and tires is the same with tighter standard tires and rims: pop the bead completely loose with side pressure, pushing it into the center well of the rim. Now, keeping the bead on the bottom of the wheel as it faces you hooked in that well, start prying the top out. If you don't get a UST bead off the shelf that creates the air seal...you'll snap every tire lever you own trying to get it off.

I've had frustrated customers come in with fistfuls of broken tire levers and red faces...and red faces again after I removed the tire with no tools at all. I can imagine it was even tougher for you after cutting the tire off and having nothing to grab onto.
