Pull the stuck side toward the center of the rim. Pull with all your might. The bead has ramped up onto the rim ledge to form a tight seal, which is a good thing. It needs to come off the same way it went on, from the center of the rim. Trying to pry a sealed rim off the outside of the rim wall is nearly impossible for a tire/rim that has a good seal. Forcing it will probably damage the tire, rendering it useless on the tire. The only thing left to do after you rip a bead apart is to make a belt out of it.

I had a tire where the bead just got welded in. I couldn’t get it out no matter what. I took it to my LBS and they couldn’t get it out. I ended up cutting the tire and was finally able to lever it out with about an hour of work. Complete nightmare.

Lay wheel on the ground. Step on the tire with one foot, as close to the rim as possible.
Now slowly apply increasing weight to the opposite end of the wheel with your other feet.

Had one like this on a carbon rim so I had to be careful the tire was worn and leaking I ended up slicing it down the middle with a razor blade then slowly cut to the bead and pried it up with a thin flat blade screwdriver and cut it thru

I usually hold the rim with one of my legs at the bottom and the pull the side towards the center and down with all my weight.

At one point Paneracer tyres were a little bigger in their bead circumference (just a tad), and I could use them so the customer could at least change the tube if they’re on a training ride. BUT THEN, I got this wheel with a rim that wasn’t conforming to anything. So I measured it and in the gutter of the rim it was 7mm longer than any other rim in the shop!! Needless to say, we changed the rim.

Park tool PTS-1 tyre seating tool…. Or REALLY strong thumbs.

Get them warm/hot they’ll be more pliable.

Table vice.
Put some cloth over the vice to not damage your rim. Clamp the tyre itself (NOT THE RIM!!!) tightly. Carefully tilt the tyre towards yourself. This will compress the rubber and take it off the rim.
I did this for a set of WTB gravel tyres that were fully stuck to the side of the rim, no amount of leverage, tools or any other solution would work. For what it’s worth, the first time I did it I put a small scratch on my rim as I tilted it so be very careful.

Liquid silicone grease between bead and rim sidewall. Put the rim down on a bucket or something similar and push down on the bead until it pop off.

As a bike mechanic it takes less than 30
Sec to fit any tire to any rim. I would like to explain how it is, but…. How can I explain 20 years and thousands tires?

Got it off with sore hands and brute strength. If anyone’s still here – is this okay to ride on for a bit? I couldn’t bend it back into place. :,)

Did you drop the bead into the center of the rim?
