I would let my tensiometer answer that question. If the drive-side spokes are below the max tension rating of the rim (with the tire off!), I'd go ahead and add a bit of tension to the non-drive-side spokes, knowing that this will pull up the drive-side spokes as well. But if the DS spokes are at or above the max rating, I'd let a bit of tension out of them first. That might be enough to re-center the wheel without adding more tension to the NDS spokes.
