I plan on ditching them, just waiting for the $$ if ya know what I mean.
At stock height the 305/70/16 will rub the rear fenders when stuffed or if you hit a big bump/dip in the road at speed.305/70r16 will turn out to be about 33/12. Should fit on stock height. You will need about 4.5 inches of backspace to avoid rubbing
Edit: Thinking now, I don't know that they make 305/75r16. 305/70r16 = 33x12
