Joe.... I am not that well veresed in it, but here is my opinion thus far....
35's with a body lift and keys will require an aftermarket wheel of less then 5" backspacing in order to clear properly in the rear, however you will have clearance issues on the front....
I have a cladded AV not a wbh... so I can only guess as to the issues on the front, but in the rear you will rub on the points as I did if you run stock rims.
I had 315/70-17's on my AV with stock rims, and got completly fed up with the rubbing and bs of the setup....
Now if you are willing to take a sawsall to your inner fenders and front bumper then they will work with aftermarket wheels of the right backspacing.... and the right rim width.
I am now running 325/60-18's and have no rubbing in the back, but minor rubbing in the front, which I am dealing with between the use of pliers, a razor blade and a hammer.... the rubbing issues I am having now are due to the width of the tires in combination with the fact that they are mounted on a 9.5" rim.
In all reality, the AV with a 3" body lift looks more ballanced with 33's IMHO then with 35's...... don't get me wrong... with 35's it looks sweet, but they are a tad on the big side...
A good option for you would be to run a set of tires that work out to 34" or less no wider then 305mm.... this setup should clear with no need for trimming.... but I am guessing on this due to the experience I have had thus far....
I will shut up now...
Any questions, comments, grips or complaints feel free shout at me....
