HANNOVER, Germany (Nov. 11, 2013) — Czech tire maker Mitas A.S. is developing, under license, a lower pressure farm tire that offers a 53-percent larger footprint and more than double the lateral stability than standard farm tires.
The tire maker is developing the tire—dubbed PneuTrac—in partnership with Galileo Wheel Ltd., an Israeli technology company that has been working on the design for the past several years. Mitas is showing the concept at Agritechnica 2013, the biennial farm equipment show in Hannover Nov. 12-16.
Galileo has described its "CupWheel" design as having an "accordion-shape" folding sidewall that allows the outer circumference to change its shape freely and move about the wheel center in all directions. Furthermore, while air pressure drops, the sidewall folds, not collapsing as in a standard tire, therefore generating far less heat.
Mitas claims its tests on an 18-inch rim have demonstrated the concept's benefits of a larger footprint, higher lateral stability and greater tractive force at a lower inflation pressure. PneuTrac mounts on standard rims, according to the company.
"Mitas PneuTrac boasts significantly higher productivity and lower operational costs thanks to better traction and improved transfer of power to the ground," said Andrew Mabin, Mitas' sales and marketing director.
The PneuTrac offers less soil compaction because of its lower operating pressure, said Galileo Wheel CEO Alon Hayka.
The larger footprint and higher tractive force "ensures gentle ground handling with much lower and improved distribution of pressure to the ground with less soil compaction, Mitas said.
The PneuTrac is not yet commercially available, Mr. Mabin said, but Mitas is confident it can bring it to market. He did not offer a timetable for this, though.
Mitas is showing the tire on both 18- and 38-inch rims at Agritechnica. A video demonstration of the concept is available on Galileo's website.
