shrink wrap mode that doesnt affect detail, only the overall shape

Update: surface deform can be used instead.

I've made a high poly tyre, I'd like to use it in a soft body physic sim, but it will take a looong time because of the poly count.

It would be great if I could simulate a very low poly version which has no tread etc (basically an uncapped cylinder) and then use a shrink wrap to get the very low poly version to reshape the high poly version whilst still maintaining all of the surface detail of the high poly.
