So the rears on your new setup WILL be "taller" than the fronts

Your previous setup are actually much closer matched with the rears just slightly more "taller":
Front sidewall height: 225mm x 40% = 90.00mm
Rear sidewall height: 265mm x 35% = 92.75mm
This equation gives a direct tire to tire comparison but makes no provision for the effect wheel width has on final height. I'm not saying my setup will end up better, I'll measure once mounted and confirm what the end result is.
