AWD needs less grooves since the car naturally produces more grip. The grooves allow the tire to get up to temperature quicker and provide more lateral grip due to deflection. The MR02 likes 4 grooves and at the specific depth they seem to work best. Any deeper and they get too squirmy. More grooves and straight line acceleration suffers due to a smaller contact patch.
