Here on the farm in northern Illinois, the work goes on even if it’s rainy and sloppy. The result is often deep ruts in lanes and fields. When these ruts dry, one has to drive in the ruts, which can be brutal on sidewalls. This is where the Armor-Tek3 and the abrasion- and puncture-resistant buttress design of the S/T MAXX sidewalls come into play. We pushed through lengthy, nasty, sharp-edged ruts, purposely driving the sidewalls into the rut edges, and suffered no problems. Clearly, this buttress design will also benefit those who use the tires on rocky trails.
