R:19x10" ET25 - 275/35-18 (or 285/30-19)
Option 2: More aggressive/flush fitment

R: 19x10.5" ET22 - 295/30-19 (or 285/30-19)
Option 3: Most aggressive (Similar to option 2 only the front wheels are wider)
F: 19x10" ET25 - 275/30-19
R: 19x10.5" ET22 - 295/30-19 (or 285/30-19)
* Depending on your ride height and the brand of tire you go with, 295's out back may require negative camber and/or light fender rolling.
