JOHN DEERE 3640 TIRES
The John Deere 3640 tractor offers versatile tire options ranging from 12.4-28 to 16.9-24 in the front and 16.9-38 to 18.4-38 in the rear, enabling customized traction and flotation depending on soil conditions. A wider rear tire configuration, like the 18.4-38, improves stability and reduces soil compaction, which is advantageous for use in softer, wetter fields. However, narrower front tires may challenge steering and maneuverability in tight spaces, necessitating careful selection based on operational requirements.
