Dan's latest set of tires is a quintet of 37-inch Nitto Mud Grapplers. The grip is equal to the bias-ply tires he'd used in the past, but the radial construction and overall build quality of the Grapplers is far superior to the old set of bias tires. No tire shop would touch the beadlock-wheel system, so there wasn't any sort of professional balancing in the offing. The Nittos didn't need it. Tire-and-wheel balance probably isn't 100 percent perfect, but this much is certain: Dan can drive Dixie on the highway sans death wobble. Death wobble was a big problem with the old tires, but it vanished as soon as the Mud Grapplers were in place.
