CHERY RK704 TIRES
The Chery RK704 tractor, equipped with standard agricultural tires (front: 8.3-20, rear: 12.4-28), offers balanced traction and stability on various terrains, ideal for fieldwork. The optional tire configurations (front: 8.3-24, rear: 11-32) provide increased ground clearance and potentially enhanced flotation in softer soil conditions, improving performance in wet environments. However, transitioning to larger tires may also require adjustments to the tractor's gearing and engine load management to prevent performance loss.
