In several operating conditions, especially in agriculture, Off-Highway tires need increased traction. Liquid ballasting can be useful to achieve major traction and higher adherence on the terrain as well as improved stability (lateral stiffness).
When filling the tire with liquid, it is recommended not to exceed 75% of its volume, in order to leave an air reserve of at least 25% of the tire volume. At any rate, it is important to inflate the tire at the pressure recommended by the manufacturer with reference to the loading conditions in order to maintain specific tire features such as elasticity.
In areas with a harsh climate, it is advised to add anti-freezing agents such as calcium chloride or magnesium chloride. It is highly recommended that these operations are carried out by a professional specialist only.
