Two new options for loader backhoe owners who want to use radial tires, without the expense of buying new rims, are available with the DuraForce line of construction tires. The new DuraForce radial tires are designed specifically for front axles of loader backhoes. The Dura Force 320/80R18 AT-R is approved for rim width of 9-10 inches. The 340/80R18 is approved for rim widths of 10-11 inches. They increase forward and reverse traction significantly—up to 18 percent over bias equivalent—because their larger footprint reduces wheel slip. They offer lowered costs per hour, since shorter cycle times may increase productivity. They reduce road vibration by featuring a harmonically noise-treated tread design that reduces cab noise and road vibration for reduced operator fatigue and improved operational comfort.
