This is a Schwalbe studded winter tire I bought a few months ago, and I’m not sure what exactly I did to get it like this but for some reason the bead seems to be warped or stretched. It doesn’t want to fit my rims. There’s a small section of the tire that’s popped out of the rim, and when I try to lever it back into place the bead pulls out further down.
I’ve tried this tire on two different rims with the same results, and to make doubly sure it isn’t the rims I put on one of my old Schwalbe Marathon tires which fit perfectly. Both tires are 40-635 700b.
Is this repairable? I don’t have much experience dealing with tires but I find it unusual that this tire seemed to be fine until now when I changed out the wheel.
Start putting the 2nd side of the tire opposite side from the valve, and lastly at the valve spot. Bicycle wheels usually have a small indent in the middle of the rim, and you should try to move the tire bead there as you put it on the rim, allowing more clearance to work with.
If you have the valve stem somewhere else than at the very last spot, it will block the tire bead from dropping into this indent.
Some tires just are pain in the ass to install
