Will 255/40s rub on a lowered 9.5 +12?

Minato is right, the difference is minimal. I tried to find set ups that were closest to the factory sport wheel diameter - i think the stock sports were 245/40 & 275/35. The 255/40 and 385/35 are both about 27" diameter (26.9 for fronts and 27 for rears) according to the tire calculators I used. So both fronts and backs went up as close to the same amount as possible.

I'm pretty sure I could run the 265/35 up front, certainly a 255/35 and a 30 series on the back. But I'm hoping to stick to a 40 profile up front and 35 profile in the rear to further reduce tire noise (will also be switching from Michelin Pilot Super Sports to Continental Extreme Contact DW or DWS).
