J.I. CASE 4490 TIRES
The J.I. Case 4490 tractor is equipped with versatile tire options, including Ag front tires sized 20.8-34 and various rear configurations (20.8-34, 23.1-30, 24.5-32, 30.5-32), allowing for adaptability to different soil conditions and crop types. The heavier rear tire sizes can enhance traction and stability for larger field operations, while the more standard options can provide a balance between maneuverability and traction. However, choosing the wrong size may lead to inefficiencies in power delivery and increased soil compaction, which should be evaluated based on the specific agricultural scenario.
