Chains of hard luck :) The ice chains of the tractor tested by Siivikon Sisu in video with 9mm pins. These are the chains of a decent place for any use. No sudi, no lateral lire, not even under extreme circumstances. Diameter of ice pick 9mm (8.8mm). Durable boron steel material. The large pin gives high grip and long wear resistance. Chains are delivered in pairs, in a strong wooden box. These chains were about to produce a little bit of blubbering with Siivikon Sisu's test video, it's worth checking out.Size: 12.4-36The chains play excellently, and as always, the chains require a little tea-it-yourself when installed in their places for the first time. Blue protective paint on the surface of the chains
