Pewag style European tire chains made by Konig/Thule in Italy. All the high quality heavy equipment tire chains are made in Europe because of the high manganese steel that's available, Pewag, Trygg, Norse, Weissenfels and Konig. The cross chains are square link through- hardened alloy for better traction and extra-long life. Because of the square link design, they don't need v-bars for traction which allows these chains to be flip or reversed for twice the life of regular tire chains!
