Dude, you can fit anything up to 35's easily, just depends on how much you want to cut/bend/hammer.
If you have no real need for larger tires, then don't get them.
If its your daily and you like the way it drives now, don't go much bigger.
If its a toy, then **** it, cut away and throw some 37s on.
Suspension lift (without long-traveling) doesn't really let you fit bigger tires, since the tire will still bottom out at the same place.
Getting the right backspacing, alignment, and trimming the pinch weld all make a much larger difference than any suspension lift.
