More about Tires vs. Tracks

More about Tires vs. Tracks

Tires are fine up to about 2-3” of hard crusty, wet or powdered snow. I have found that snow/sand paddles work best, even on the packed snow. The contact area of even dual tires or Maxx tires on the back just did not provide the floatation and forward motion that is required to keep the tires from just sinking in during acceleration on deeper or powdery snow. Soft powdery show has a surface tension of about 1oz./square inch. There is a reason they have specialize vehicles call snowmobiles that will outperform any other vehicle on snow. As a result a track system is required for snow deeper than 2-3 inches. The good news is that it can be done, and a couple of people already have, however you can expect to spend between $200-$400 for all the parts to make it work right at full speed. Although I have found all the appropriate materials, and have developed a solution in my CAD program with all commercially available materials, which will simply bolt on to the Stampede and E-Maxx, I think I would rather spend the money on something else. After all we only have decent snow about a month out of every year.
