Depends on how worn the other (undamaged) tire is. If the undamaged tire has good tread, then little reason to replace it.

Full sized spare does not fit in the space available in my "poorly designed" vehicle. hmm...

Also re: tire wear - there are tires now that are designed to last for only 40,000 miles.
