Unique inner tire enables quick inflation of agricultural tires

Mitas has introduced AirCell, a unique inner tire that enables the inflation of large agricultural tires by +/- 1 bar (from 0.8 bar to 1.8 bar) within half a minute – more than 10 times faster than the current method of inflation. Mitas AirCell is located on the rim inside the tire and occupies about 30% of the volume of the tire.

Mitas Aircell has been designed for the Mitas 710/75 R42 SFT, other sizes will follow. AirCell is continuously inflated to a maximum of 8 bar during tire use, releasing some of the pressure on demand enabling a rapid increase of pressure into the agricultural tire itself adjusting the pressure in seconds rather than minutes. Mitas AirCell will be available for the Fendt 900 Vario equipped with Mitas 710/75 R42 SFT starting in November 2016.

Mitas AirCell not only enables rapid inflation but also helps to release the pressure just as fast again as the volume of the outer tire is reduced by up to 30%. AirCell is not in contact with the tire itself and so it does not create any additional friction or heating. It is made from sturdy rubberized materials that retain their shape even when inflated to high pressures so the volume of the outer tire does not depend on the inflation of AirCell.

Hans-Ulrich Klose, head of the automotive engineering unit at Mitas, said, “Mitas AirCell brings advantage to farmers and contractors who need to change pressures quickly from low inflation during field work to higher pressure for better fuel efficiency during on-road transportation and vice versa.”
