mattrod, I ran my 235/75R/15 all last winter with no problems at all. Didn't have the rubbing issue till I lifted my Sporty.
I don't have a large budget. I bought the tires first. Then the warn manual hubs, then the 3"UPYOURKIA. I'm looking at more backspacing on the wheels then move into more aggressive treaded tires. The tires I run still have 95% tread so it'll be a while.
Get those bigger tires, fills the wheel well more and looks better too. Good Luck.
