I would never do this regardless of how my car was geared up.

The most amazing thing about this discussion is the absence of discussion about why you should never run a space saver spare of any size anywhere for longer than it might take to get from where you had your flat to a tire repair shop.

Space saver spares are just barely safe for emergency use only. Many, many people just do not understand this important fact. Any time we can remind people about the safety aspects, we ought to.

Space saver wheels are ugly for very good reasons. Transmission or differential wear is not among them. Seriously. I think the limits of those tires are 50 miles at no more than 50 mph.
