Those are the exact sizes I'm using on the stock sport wheels. The 275/35/19, looks like it belongs on the front and I'm using a 10mm spacer for that slightly tucked look.
Bridgestone RE050A:
305/30/19 5 mm spacer and 26.3 diameter
275/35/19 10 mm spacer and 26.5 diameter
with a 4.08 tire shredding gear ratio
