I don't have a lift and I have 265/70r16 General Grabber AT2's on mine and I do have rubbing but only when turning with the steering wheel locked to one side. Its def worth it to me cause I love the size without the lift (Id love to have a Truxx lift one day and bigger tires). The only complaint is the crappy gas mileage, I think my tires are a little heavier than BFG's but they are like half the price, def worth it to me.

He's a good link that you can compare tire sizes with different rims and how bad your spedo will be off...

It looks like my tires are 30.6" diameter and the tires you want (255/70/17) are 30.1", you should be okay. The guy with 265/65/18 def has some rubbing since it is 31.6" diameter.

I have 285/70/17 with truxx lift, the wheels are -12 offset. They stick out an inch or two too much but a 0 or -6 may be better. Rub's a little at a hard turn. There had to be some trimming in the front but it was worth it. Have a shop install the lift and trimm, if you want it done right.
