can i use 215/55/16 for the front rims and use 205/55/16 for the back rims?

made a mistake in buying some rims from some guy. I needed to replace one rim for the one in front. the new rims, set of 4, 3 with good tires and one not with 215/55/16. should i put the new rims with the bigger tires in the front or the back? i just want to change two and keep two of the old ones with 205/55/16.

Or should i just have the same profile of tires in all?
my car is a 2wd
