FYI, my OEM (18" 400m staggered) sizes:

Front: 225/50R18 = 26.858"
Rear: 255/45R18 = 27.035"

My summer setup with Pilot Super Sports (19"x8.5" front, 19"x9.5" rear):
Front: 235/40R19 = 26.402" (1.700% smaller than OEM front)
Rear: 275/35R19 = 26.579" (1.689% smaller than OME rear)

No issues that I know of yet! Running great!
Originally, I was recommended 235/45R19 and 265/40R19, which would have been perfect, but PSS's didn't come in those sizes.
