New-Style Tire Works Like A Rubber Track
A round rubber pneumatic tire that flattens out under load, allowing the bottom surface to take on the shape of a flat rubber track, is being developed by the Mitas Tire Company based in the Czech Republic, (www.mitasag.com).
  According to Mitas, the PneuTracís footprint is 53 percent larger than that of a standard tire, and its lateral stability is 167 percent higher. Instead of the sidewalls bulging out at low pressure, the sidewalls of the PneuTrac actually concave or deflect to the inside of the tire. The design elongates the tread so that the imprint becomes longer and the tire imprint looks more like a track than a tire. It results in better traction, less slippage, and less soil compaction.
  Mitas research and development department in Europe is testing PneuTrac tires in 18, 28 and 38-in. sizes. The tires arenít expected to be available for at least 2 to 3 years.
