"The footprint and traction force of Mitas PneuTrac and rubber tracks are superior to those of traditional pneumatic tyres. The next step is to compare PneuTrac and rubber tracks and see how close they will come,” said Andrew Mabin, Mitas' sales and marketing director. “We are getting closer to a clearer release date being available. Our goal is to launch PneuTrac in roughly two years.”
PneuTrac footprint measurment vs. standard tyre
Mitas is conducting field tests in the Czech Republic with a John Deere 6150R tractor mounted with 480/65 R28 PneuTrac on the front axle and 600/65 R38 PneuTrac on the rear. The results show the traction force of Mitas 600/65 R38 PneuTrac is approx. 25% higher than a standard tyre and, compared with an IF-rated tyre, PneuTrac delivers approx. 15% better traction. Taking a closer look at the 480/65 R28 PneuTrac, it has approx. 10% advantage in traction force over a standard tyre and approx. 7% over the IF tyre.
“The results of the first field tests that are under way in the Czech Republic give us a good feel for continuing the successful development of the Mitas PneuTrac concept,” said Andrew Mabin, Mitas' sales and marketing director.
The slippage and traction force is measured under several modes of driving, and the result is the evaluation of traction force under the slippage that normally occurs during regular farm work (about 15%). The results are based on measurements conducted on July 22, 2015. Measurements are done by Research Institute of Agricultural Engineering, p.r.i.
“The field tests have so far demonstrated the clear advantages of PneuTrac over conventional tyre designs and confirmed previously released lab test results. The most important PneuTrac benefits are a larger footprint, greater tractive force and also higher lateral stability at a lower inflation pressure when compared with the standard tyre,” Mabin added.
Mitas is developing its PneuTrac concept with its partner, Galileo Wheel Ltd. Mitas and Galileo had intensively worked for four years to build the PneuTrac concept from an idea to lab testing and finally to the field demonstration. The award-winning tyre concept had its public premiere in 2013 at the Agritechnica fair in Germany, where Mitas presented 280/70 R18 PneuTrac and 600/65 R38 PneuTrac. At the SIMA fair in Paris in February 2015, Mitas presented the 480/65 R28 PneuTrac, which was the third size of the revolutionary concept.
