The capability of the engine + gearing would affect that decision, the more motor and lower gearing the more rear bias is desired.

W/ a stockish 3.2 8 to 9 & 9 to 10 is a good place to be

8 & 10 w/ 225/45 & 255/40 is pretty efficient and provides a good balance, 215/45 & 245/40 would be a bit more efficient and get the most from the tires(though the 245 on a 10 is a bit of a stretch)

unfortunately in 17 there aren't any other good street tires.

When I set my 911 up w/ 17s I chose 8 & 9.5(8.5 isn't a real good fit on a n/b otherwise I would have gone w/ 8.5 front) 235/40 & 275/35 Bridgestones were the original tire. This would have been a max Carrera body fitment which retained a modicum of efficiency) Unfortunately they became na shortly afterward. Now these sizes are only available in track rubber.

For street use there is no significant down side going w/ 8 & 10 225/45 & 255/40 x17
