Actually, as slip angle is increased, the cornering force increases
to a peak, and then is approximately constant right out to 90 deg.
Once the slip angle is past the peak you can think of the tire as
just a slab of rubber sliding on the road--changing the slip angle
doesn't have much effect on the side force.

So, the tread won't spring back as you suggest.  If the
the car has spun half-way-round and is moving backwards, the tread
will re-center when the slip angles are near zero (or 180, if you
prefer to think of it that way).
