Hi! Truthfully it depends on the certain situation that is used. Usually in the early spring, wide tires are used before planting to help with the weight distribution and that if there is any moisture in the ground that they will not get their equipment stuck. When they use skinnier tires it is usually in-season after the vegetation is visible so that with proper spacing they can apply product and drive between rows without running the crops over. I believe there are alternative methods in process to limit compaction but as of now, at least from my experience that’s what I’ve seen. Great point though!
