Hey bad -
The 315-30/18 has an overall height of 94.50mm (this is the whole wheel/tire)
The 265-40/17 has an overall height of 106.00mm
The spreadsheet shows a delta of -2.6% in red, which is supposed to indicate too much variance front-to-rear.
FYI, switching to a 275/35-17 front (which would help to remove a little udersteer, especially with the meaty 315 rear) is a delta of only 0.4% (it has an overall height of 96.25
Hope that helps!
DOH! Had to edit this - I've been thinking about an 18" front, and the 275-35/18 is pretty common, but I don't think that's a common fitment for 17", so here's the info for a 265-35/17 (which is available in a Michelin Pilot):
92.75 height with a front-to-rear delta (still using the 315 rear) of 1.5% (which is not highlighted red,)
