Just checked. All outside edges on the outside. MPS4S are not directional.
Good idea, though. Reminds me: I once had an XC90 that was pulling slightly to the left under acceleration. Turned out it had a replacement tire on the front right that was a different brand. Car was used and I hadn't noticed when I bought it.
