Bend a mesh inward with rotation?

Hello, :)

I would like to know:

• how can I apply any kind of modifiers or whatever, that can bend a mesh inward following a circle spline please ? I already tested Bend and twist but nothing solved my problems. Thanks for your help.

I'm making a tire actually. i'm adding a photo for you to understand.

Ok, i found a way to "solve" the problem roughly, even though the result is not 100% accurate, using front view/ soft selection scaling, but it's really close to what i wanted, just the edge are a little bit squeezed.
