I ordered two new tires, or mantles I believe is what they’re called. One looked fine and I mounted it on my bike. The other one looks quite warped. It’s not soft but rather pretty sturdy, so I worry it wont sit correctly if I try to install it.

I’m a newb to this, first time I even changed a tube by myself. So let me know if I need to add more information.

Thanks!

Edit: thanks everyone! I’ll give it a try tomorrow.

It doesn't matter what it looks like before it's mounted. It could be completely misshapen. Especially if the bead is not steel. Mount it on and see if it sits correctly once you inflate it.

I use Panaracer Pasela or Gravel King. Those come completely flat so there isn't even a round structure to go into the rim. I have to unfold them, then shape back into a tire before I can put it on the rim. It's annoying. Once I inflate them, they get into a perfect tire shape, perfectly sitting into the rim bead channels.
