wheel fitment questions can be answered here...

if you're not planning on changing any suspension components/settings, on a non-///m an 8.5" wheel in front with any offset more aggressive than et40 will most likely rub on the fender liners at 235 or wider. many of the other members here have had that result. 275 in back shouldn't be too big of an issue as long as the offsets are appropriate. if this were me looking at this upgrade, i'd install the following...

235/35R19 on 8.5" et40
275/30R19 on 9.5" et45

this should be no rubbing on stock susp/settings, and also no stretched tire look on the wheel. definitely consider an alignment after install though... adding an inch to tread width and increasing rear track will do weird things to toe-in.
