Removing tire with inserts - can't get the bead to separate!

I have a tire that will not separate the bead from the rim (they’re even hookless) no matter how hard I press. They have inserts in them and this is the first time I’ve ever experienced this, so I’m guessing this is a common problem (a friend of mine is having this issue right now too).

I know how hard inserts are to install, but taking the tire off is something I never expected problems with.

Does anyone have any tricks to help get the tire off?

Park Tool BMT-1 is your friend :smiling_face_with_sunglasses:

Not quite identical situation, but recently worked through a similar “unable to displace tyre from bead” issue with Vitoria tyres and with the help of friends on this forum was made aware of Parktool tyre bead tool that fixed the issue for me. BMT-1 Tire Bead Breaker | Park Tool

Thanks fellas! I probably won’t go out and buy the BMT-1 just for this, but that gives me some ideas on other clamping tools I have kicking around that’ll do the same thing.

Happy to loan you mine if needed - can e-mail me directly. FYI, I tried two other tools (both inadequate) before resorting to the Parktool

Thanks! I’ll see how I go!

I wonder if a generic welding clamp pliers would work rather than paying the bicycle tax. Add some 3d printed feet if you want to show off

@wade_wallace - Pro tip I learned from @Dave_Rome …. in a pinch you can clamp the tyre in a bike workstand clamp and then rotate the wheel to separate the bead. I had the same issue unseating a tyre with an insert and this approach did the trick.

My mate just tried something like this and he said that the lack of rubber grip on the ends made the tire keep slipping out. As you say, the printed feet would make it work.

Great idea! (If I had that type of repair stand)

I give up. 2 hrs of this and getting nowhere

CushCore bead dropper tyre lever and a big plastic bin.

Success! Separating the grippers and working the tyre inwards with a lever into the wheel trough (or whatever it’s called) did the trick.

None of the YouTube techniques worked for me. This must have been a tough case.

Pedro’s tyre levers to the rescue!

I had Maxxis DHF/DHR 29x3.0 mounted on 40mm (?) hookless carbon rims with Panzer inserts.

I, nor the shop could get off. Eventually the Maxxis rep suggested a shop and he used the Pedros downhill levers and was able to break the bead. I now carry said downhill lever with me.

I told this to someone a year later, and although they almost had a heart attack in the process, they somehow managed to get the tyre off (with the insert in) using just a tyre lever in their shop.

Each of us took away an entirely different conclusion from what happened.

My biggest mistake at the start of this process was trying to hook the tire with the lever and remove it the same way I’d removed hundreds of tires in the past (i.e. hook it and lift it over the rim). But what I eventually realised is that breaking the bead by pushing it into the middle of the rim is the right technique. It still made a grown man cry a few times though!

I have a suspicion that SRAM and Shimano bankrolled tyre inserts so that we’d all stop complaining about bleeding brakes.

This is the sort of story that one day, Dave Rome will write a book about, but it will never be published due to a suppression order.

There is a reason Wade isn’t on Geek Warning. I have never tried to remove a tyre without pushing it into the centre of the rim well first.

The first time I needed to remove a tyre with an insert in it I gave up and cut the tyre off - since it was worn out anyway.
