Spare tire different size???

Question for you dually tire experts.
My dually has 265-75-16 (31.64") all around.
My spare tire is a 215-85-16. (30.38")
I think the spare would be fine in the front but what about the rear?
I'm thinking to use the smaller rear tire on the outside or not at all.

If a rear goes flat, put spare on front and move front to rear. You cannot run different height tires together on the rear. The difference in circumference would create issues with heat.

Thanks for the feedback.

You really don't need a spare at all. Just run a single on the rear until you get to the tire shop.

...unless you are, say, towing something heavy and don't want to leave it behind on the side of the road while you go and get the tire fixed...
