You don't need that much traction on a high gravity planet and the two extra wheels become unnecessary.
On the Moon, Mars, or anywhere else where the gravitational acceleration is below 5 m/s², you want six wheels, because at least two of them will always not contact the ground due to poor traction and movement over uneven terrain.
