What is the rear tires. The 225/45 is slightly wider (10mm) and taller (9mm). The 235 is wider still but shorter than your existing tire by 5.5mm. All small differences so I'd see if you can fit the wider of the two options up front, and which has the better selection of tires available.
255/40 in a 17x8 got the rear
