CHALLENGER MT665D TIRES
The Challenger MT665D, equipped with standard agricultural tires of size 480/70R34 in the front and 520/85R46 in the rear, offers a balanced combination of traction and flotation, enhancing field performance in diverse soil conditions. The larger rear tires improve stability and weight distribution, crucial for heavy implements, while the front tires provide adequate steering control and maneuverability. However, the tire sizes may limit some narrow-row crop applications, necessitating a careful assessment of field conditions and implement compatibility.
