You don't want to be using the 215/70R16's. The 235/65R16's have a higher load rating and that translates into better rolling resistance - about 2% better. This is larger than the 0.6% you get with the diameter difference.

Plus, there is the safety issue using a tire with a lower load rating.

But there is another consideration. The difference between tires is an even larger affect on fuel economy. So look this over very carefully.
