You can fit a 17x11" rim with 6" backspacing in the rear and a 9.5" rim with 5" backspacing in front.
315/35/17's in back and 275/40/17's in the front.
You might be able to fit a 285 up front with minimum rubbing.
I'm almost certain a 335/35/17 will fit in back but it would need at least 6.5" backspacing on an 11" rim which no one makes, so spacers would have to be used.
They'd stick out over an inch past the wheel well also. It'd look like **** but handle and accelerate like crazy.
