I've been considering the 285/40r17 tire myself, paired with the 225/50r15 up front. Available as a matched set in the Pirelli P Zero model. In my opinion the 285/40R17 (26" diameter) is too small in diameter to pair with any front tire larger than 24.3" diameter.
The chart details options where you can acquire the same make and model for all 4 corners, with good availability, correct diameters, etc.
