Tire size question

just a quick question:

My 2016 sport came with 17 inch wheels including spare. I replaced the 4 stock wheels with 16s and got ko2 285/85-16.

I kept the 17 inch spare and didn't replace the rubber but figure I should replace with something same size but don't want to replace the rim. Something in a skinnier profile would also be good.

Would a 255/70-17 fit?

 

I mean would. A 255/70-17 be the same hight as a 285/85-16?
