  • Page 64: Tyres - Air Pressure: Manufacturer's Recommendations

    If there is a change to a different version of tyre or wheel rim, a different tyre pressure may apply — contact Gremo. Danger! To avoid serious accidents, always follow directions for inflating tyres.
  • Page 65 500 kPa 2 20 100 kPa = 1 bar All tyres are from the factory (Gremo) and inflated to 450 kPa. The minimum pressure is approximately 50 kPa below the stated values and the maximum pressure is around 50 kPa above the stated values.
  • Page 66 3.10.1 Filling of fluid in forestry tyres The tyres can be filled with fluid to increase the machine’s stability and traction Gremo recommends filling 50% of the tyres’ volume. Maximum permitted is 75%. The fluid should consist of water. At temperatures below Fig.
  • Page 67 Calcium chloride increases the fluid’s density by up to 1.2 kg/litre in a 35% blend. Fluid-filled tyres are less elastic owing to their smaller air volume and are therefore more vulnerable to spot loads. Rolling resistance and the dynamic forces acting on the wheel rims and suspension components are also higher.
