KUBOTA ST-30 TIRES
The Kubota ST-30 tractor features standard agricultural tires (6.00-12 front, 9.5-22 rear), enhancing traction and stability for various field applications. Alternatively, it can be equipped with lawn/turf tires (24x8.50-14 front, 13.6-16 rear), designed to minimize soil compaction, making it suitable for landscaping and maintenance tasks. The choice of tires directly impacts performance; agricultural tires excel in rough terrain, while turf tires offer better maneuverability on grassed areas.
