Important: The Tire Size in this listing is in the factory publication for your tractor. Please confirm by checking the sidewall of the tire that this size is correct for your Tractor and that you have a minimum of 1.5 inches of clearance. Heavy Duty Tire Chain is made of thicker cross chain and thicker side chain and fasteners. Twisted Link Chains are recommended for pavement and concrete. 2 link snow chains, cross chains occur every other side chain link giving consistent ride with less grip-slip like a 4 link chain. Optional Tensioner is recommended for maximum life and performance of chains. For easier installation of two and four link chains see our Sno-Chain Ramps.
