As you likely know, deep wheel tracks are a headache in the field. They lead to low crop clearance and can cause your pivot or linear to get stuck mid-rotation.
A common misconception is that a longer or heavier span automatically means deeper wheel tracks. This is simply not true. Pivot weight has little to do with deep wheel tracks. The key to minimizing ruts is ensuring that tires are properly inflated. Tire inflation directly affects ground pressure, which is the leading cause of deep wheel tracks. There is actually an equation you can use to determine the best tire pressure. And, proper inflation also maximizes tire life.
