Title: Force tirechanges to complete.

If there was another part mounted on the tire (e.g. a box on a motorcycle), the tirechange would fail but still consume the tire.
The change forces tirechanges to complete, i.e. we can change tires where removing and then adding the tire seperately would fail.
