WLL with 10,000 lb. break strength; low-stretch webbing and reinforced stitching ADJUSTS TO ANY TIRE SIZE: Molded rubber blocks with tread-lock teeth grip tire surface for a centered, non-slip hold on any vehicle tire size ac's Tire Block Strap Pack provides a sleek, minimal-contact method for securing your show car for transport. Simply drape the 2" wide strap over your vehicle's tire and tighten the ratchet to compress the three molded rubber tire blocks against the tire. The tread-lock teeth on each rubber block bite into the tire's rain groove to keep the strap centered. Including four 10' straps, four strap wraps and one large tool bag, one of the advantages of Mac's Tire Block Strap Pack is that no part of the tie downs come into contact with the hard surfaces of your vehicle and you always have a place to store your straps. By avoiding contact with the axle, chassis or wheels, risk of marring fine finishes is eliminated. This low-profile design is also favored by car owners who prefer a tie down that doesn't obscure any of the car's detail. The generous 10' strap and moveable tire blocks adjust to fit any tire size, making them ideal for commercial carriers or anyone needing to secure a variety of vehicles. The E-Track attachment option supports both standard E-Track or A-Track (aluminum) track systems. Because an E-Track system's lateral load capability is lower than its vertical load capability, we've designed this system with a double fitting on the fixed end.
