I believed what "3002tii" meant was your new tires will be:
Front sidewall height: 225mm x 35% = 78.75mm
Rear sidewall height: 255mm x 35% = 89.25mm

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
