John Deere Tire Chains LP39862: 24×12-12 Tires. TerraGrip Traction Belts are the innovative traction aid designed to Protect the Driving Surface. They offer enhanced traction on all surfaces and outperform traditional chains in snow, mud, dirt and wet asphalt or concrete. On top of that, they will not scratch or chip concrete, asphalt or aggregate drive or walkways. We utilize the proven reliability of the traditional steel chain attachment system and combine it with the performance and durability of reinforced rubber slats. The rubber slats wrap around the tire so only rubber touches the driving surface. The result is aggressive traction without the risk of damage associated with traditional chains. ·Rubber slats surround the tire and will not damage driveways or sidewalks. ·No steel touches the driving surface. ·Easy installation utilizing a traditional steel chain attachment system. ·Improved traction on all surfaces especially loose material snow, dirt, mud, sand etc. ·Approved for John Deere X300, X500 and X700 Series Tractors. Additional tire sizes are available. Special Note for Four-Wheel Steer Models ONLY. X500 – Requires Wheel Stop Adjustment (see Tractor Manual). X300 – No Additional Requirements.
