What size tires will fit on stock dart 15" wheels?

on overall diameter on the list for the P245/60R15 it says 26.54.
on overall diameter on the list for the P215/65R15 it says 25.98.
So, that means that the rear tires will still be .56 higher than the front?
Also, going by each size's recommended rim width, it looks like 7's all around will still fit both...
So, you think this would work? Or am I missing something?
Thank you so much for your help...
