I recently put on new tires - nightmare at the shop, and it took them four tries to get everything right (mounted front tire on rear wheel and rear tire on front wheel / swapped rear wheel to front and front wheel to rear / mounted directional tires in wrong direction).

Wheels are 18x8.5ET32 front, 18x9.5ET45 (+5mm spacer, so essentially ET40) rear.

Tires are meaty RE-71R, 235/40/18 front and 265/35/18 rear. No rub on OEM sport springs.

The interesting thing is, when the shop initially mounted one of the 265 width tires on the front 8.5" wheel, I had no rub at full lock. I didn't drive it far enough to deal with turning + suspension compression due to potholes, but I was surprised it didn't rub.

I may move to a 245/275 setup next, or even a 255/275 setup.

Update: 235/40/18 rubs slightly under hard cornering with stock sport springs. A 255/35/18 tire may work better on the front due to the lower profile.
