Does the placement need to be close to the center or dropped wheel then for good contact with the ground? I would think the rocking of the tank drive could impact the traction of the idler.
We actively powered them down with a 5/16" bore pneumatic cylinder.

We had them installed far left/right extreme for precision in turns, and roughly centered between the front/middle wheels on our heavier side.

It allowed us to do 6 or so linear movements and drive about a combined 40' (and probably 720* of turns) and still measure within 2" (maybe better) our final position.
