To add, I'd actually prefer if on an ED they would allow you to get the summer tires/323 wheel option with 225/45 R18's all around and not go staggered with 225/40's on the rear. I prefer square setups so that tires can be rotated for even wear. I haven't yet found a good reason for staggered setups except to keep people who don't know how to drive correctly from oversteering. I think it would be a PIA if the rear and front wheels don't wear down evenly(can't be rotated) and you end up having to replace front and rear wheels at different times or throwing away front tires with tread left. I'd also expect having, for example, 9/32 left on the front and 2/32 on the rear wouldn't be good for the awd diff and could cause more wear or early failure. Not to mention grip would be different in the front and rear which would really hurt performance in dry and wet.
