Hello,
I’m searching for solution to deform a 2D tire, when its collide with ground. Just a little bit press edges of sprite, where it lays on the ground just like in the picture below.
I know jelly sprites, but it deform a whole sprite.
Maybe have 2 separate sprites, one for the outer ring, and one for the inner. This way you can lock the inner, but deform the outer all you want 
Yeah I considered that, but how to deform that outer layer?
I think what people do is they turn the sprite into a mesh, such as a plane with 2d collider, with the sprite as its texture and deform the mesh.
I think you can see an example of it in this video
