Super Z® OTR ZT-143
Super Z® OTR is a product built specifically for durability, performance and easier handling. Its diagonal pattern cross member design provides smooth, consistent, aggressive traction. Z-OTR Chain is perfect for that special equipment that requires superior traction, low clearance, and ability to operate in special conditions. Used greatly by airports on pushbacks, and to transport cranes from job sites. Special military applications are in use.
Super Z® OTR's 0.685" diameter manganese alloy traction coils provide the lowest operating cost per mile of any traction product. They're easy to install and the included rubber tensioners adjust the product on the tire while the vehicle is in motion, so there is no need to stop and re-tighten.

Chain tensioners ARE required and included.
