Shahram,
With your lift and tires you should be fine. Only time I ran Millers (with Sam) I had no lift and 285's. Bent the stock running boards (nice warning system - and good excuse for sliders!) and that was it. Not being as well set up as Sam, I'd chime in and say you'll be fine with a 3" lift.
X3. The only time I ran it (2yrs. ago) I was not lifted. I was on 33's had sliders and the slee t-case skid. I used all of those to get through without a hitch. With that being said, a lift would have more than likely gotten me through with out the use of the sliders and skid (I also had the ARB bumper so I had a lot of weight on those poor little lexus springs). A lot could have changed there in 2 yrs though.
