There might also be some tire manufacturing tolerances got a little fucky during covid(or on certain production lines). Not sure what can cause issues when the bead is 2cm out of whack. Why can't tire beads just be standardized? As far as I understand, there is no benefit to having beads fit onto the rim super tight. I recall a few years ago I took a different mountain bike to a bike shop to get new tires, and after I picked out the tires I wanted, the guy installing them came to me and told me I have to pick out another set because he couldn't get the bead around my rims. This isn't the first time this has happened to me. I'm probably going to have to teke these wheels to my local bike shop and have them try to get the tire on, but I have a feeling they won't be able to, and I'll have to just get a new set of tires which have a slightly larger bead. The diameter of the tire bead is about 2 cm smaller than the diameter of the rim. I managed to get both tires removed, but now I can't get either one of them back on. I actually broke one of my tire levers clean in half while trying to get one of the tires off.

It turns out it wasn't glued, it just fit on extremely tightly. At first I thought the tire were tubeless since it seemed the bead was glued to the rim. So I bought a set Tannus Armor and set out to install it. Has anyone here ever had a problem with a tire that has a too small diameter bead and it won't fit onto your rim? My new enduro bike ended up getting a flat tire on my first ride.
