Tyre Inflation Systems

The advantages of an adjusted tire pressure

The advantages of an adjusted tyre pressure

  • Reduced fuel consumption of the towing tractor in the field and on the road (10 % – 15 %)
  • Example: A tire rut depth of 5 cm is equivalent to driving uphill at a gradient of 5 %!
  • Reduced rolling resistance in the field and on the road
  • Higher ride stability on the road, even at higher speeds
  • Reduced tyre rut depth as a result of the much larger tire footprint
  • Far greater tractive force due to better interlocking of the tire tread with the ground
  • No/reduced harmful ground compaction
  • Increased plant yields
  • Effective self-cleaning of the tire tread via the flexing of the tires
  • Less tire damage/wear

Using central tire inflation systems also gives contractors a real competitive advantage. Not only because customers are increasingly demanding that the tire pressure of their tractors be as low as possible, but also because this technology allows customers to extend their seasons. Even with difficult ground conditions, it is often still possible to drive over the ground with a reduced tire pressure.
