The Firestone Super All Traction 23° R-1 tractor tire is a long-wear and durable bias-ply tire for 2WD farm tractors, 4WD farm tractors, or Mechanical Front Wheel Drive tractors and combines. It comes as the original equipment tire from John Deere, Kubota, and New Holland Tractors.
The 23-degree bar angle is proven to provide the best overall traction and wear-life. The Lugs are positioned to reduce vibration and shake which is harmful to the equipment over long periods of time, and uncomfortable for the operator. The tread also features a wide open-center that reduces mud build up in the tread.
