FIAT 450 TIRES
The Fiat 450 tractor is available in both 2WD and 4WD configurations, with 2WD utilizing standard agricultural tires (Front: 6.00-16, Rear: 12.4/11-28) and 4WD deploying larger tires (Front: 7.50-20, Rear: 12.4/11-28) for enhanced traction. The 4WD variant provides improved stability and maneuverability on challenging terrain, making it ideal for demanding agricultural tasks, while the 2WD version may have a lower initial purchase cost but may struggle in wet or uneven fields. Consider the operating conditions and load requirements to maximize efficiency and performance in your agricultural operations.
