Mitas, part of Trelleborg Group, is extending its range of Cyclic Harvesting Operation (CHO) tires and presents two new sizes this month.

Mitas CHO tires are designed for combine harvesters, grain carts and similar implements. Their unique construction uses hexacore technology, steel breakers and flexible sidewalls and allows for larger loads at a lower tire pressure to protect the soil. Mitas CHO tires are a favorite among leading agricultural machinery producers.

Pavel Kott, Product Manager for Mitas agricultural tires, said: “Cyclic loads when filling and emptying corn tanks, for instance, can vary significantly, by more than twice in some cases. At high inflation pressures, this leads uncompromisingly to soil compaction. The solution is a Mitas CHO tire as it is capable of carrying more load at a lower tire pressure.”

 Kott added: “Mitas CHO tires are a popular original fitment preferred by major combine harvester manufacturers. The range extension of CHO tires is a directresponse to their needs and tire size specifications and we now offer nine sizes of CHO tires on worldwide markets. An additional three sizes will be released in first quarter of 2017.”

With CHO, Mitas has designed a range of extremely powerful tires for large combine harvesters. CHO is capable of higher maximum loads than standard tires and at the same time, the tire permits higher yields through gentler ground handling in the field and offers more comfort on the road. The larger footprint of Mitas CHO tires helps to distribute loads equally, which has a positive influence on lower soil compaction. Mitas CHO fulfills all legal requirements on vehicle widths and are mountable on standard rims.

 Sizes of Mitas CHO tires include:
