Dealing with a flat tire

I recently purchased a 2011 370Z and was pleasantly surprised to learn that it contained a temporary spare tire - I was expecting a can of Slime blow-up! However on closer inspection I noticed it was an 18 inch tire whereas the ones on the ground are 19s. I'm certainly no tire expert, but would have expected that all the wheels be the same diameter. I would guess the the temporary 18 could be mounted on the front with no problem as there is no differential to damage. However, putting an 18 on the rear with the same drive shaft with a 19 could cause a problem.

If faced with this situation, my plan would be to put the temporary 18 on the front, and use the good 19 front tire on the rear. Does this sound like a plan? I know that the rear whels can't be mounted on the front, but is there any reason the the front tire couldn't be mounted on the rear?
