I don't know about your commute, but during mine, I am not constantly breaking traction.
If you are that concerned about diff wear, you should probably avoid driving your car any direction except for straight. The wheels turning different speeds while turning might cause damage.
Running mismatched compound tires might not be a good idea for a few reasons, but angering the diffs probably isn't one of them.
