TIVOLI, Italy (Sept. 3, 2013) — Trelleborg Wheel Systems S.p.A. has developed a "double-lug" tread pattern for its farm tractor drive tires that it claims delivers "progressive" traction under varying soil conditions while offering improved flotation at the same time.
The design concept, to be marketed under a "ProgressiveTraction" moniker, will debut at the Agritechica 2013 farm industry trade show in Hannover, Germany, Nov. 10-16.
Trelleborg said the idea, under development for the past two years, is still in the concept phase. The first tires, in size 650/65R38, are now undergoing field testing.
Piero Mancinelli, R&D director, Trelleborg agricultural and forestry tires, said the design concept is targeted at the new generation of tractors and transmissions that offer more power and torque.
"To cope with these requirements, agricultural tires have been growing both in terms of width and overall diameter, becoming larger and larger," Mr. Mancinelli said. "The ambition of 'ProgressiveTraction' technology is to increase tire efficiency and performance by simultaneously working on the tire's dimension while re-engineering the traditional tread."
