JOHN DEERE 8100 TIRES
The John Deere 8100, equipped with 2WD and standard agricultural tires, offers a robust balance between power and fuel efficiency, making it ideal for moderate tillage and fieldwork. The front tire sizes of 11.00-24 or 14.9R34 paired with 18.4R46 rears improve traction and stability, although the 2WD configuration may limit performance in muddy conditions or on slopes. Operators should consider their specific terrain and workload requirements, as a 4WD option might provide improved maneuverability and soil preservation in challenging environments.
