I'm not saying that they shouldn't have different size sidewalls (aspect ratio's), I'm just saying from an aesthetic point the rear sidewall should be the same height or taller than the front.
If you look at a 275/45 tire it is 275mm wide and 45% as tall. 275mmx.45=123.75mm
A 295/40 is 295mmx.40=118mm.
If it would fit, you would rather run a 305/40 or 315/40 in the rear to keep the sidewall (and thus the overall diameter as close to the front as possible). Or keep the 295 in the rear and run a 265 in front.
If you look at the WK's they ran a 255/45 and 285/40 combo. Do the math and you will see there is less than 1mm difference.
