On a FWD car, I would say put the toy spare on the rear and do 50 MPH all the
way in to your destination.
On a BMW, not so much. Running with the spare on the rear will wear your
differential. Running the spare on the front is pretty dangerous. I'd say
repair the tire with a plug-patch. If you can't find someone to patch it, put
a plug in the tire and run it on the rear and keep the speed down.
