[Vehicles]how to create effect deflated tires

Hi, how can I create deflated tires like this,
how about world position offset? i need this on moving vehicle, like if tire deform from vehicle weight.

If you want a simple solution which will work I’d suggest modelling the tire as flat, not rotating it, and instead rotating the texture maps on it.

You could use world position offsets but I think that’ll be a lot more difficult to get right, making the vertices move correctly as the approach the bulge and leave is not going to be simple and likely will require a lot more geometry than a normal tire would.
