What is the proper method to fill machine tires with water ballast?

The proper method to fill machine tires with water ballast involves jacking up the wheel and positioning the valve at the top of the tire. This method ensures that the air inside the tire can escape effectively while the water is being added, preventing air pockets from forming which could lead to an imbalance. After filling the tire with water, adding antifreeze protects against freezing conditions, especially in colder climates. Once the water ballast is filled and the antifreeze is added, the tire can then be inflated to the correct pressure. This sequence is important for maintaining both the performance and safety of the machine.

The other methods do not accommodate the necessary steps effectively. For instance, filling with the wheel on the ground might not allow for proper ventilation of the air in the tire. Removing the wheel adds unnecessary complexity and risk. Finally, filling from the bottom without raising the wheel could lead to an incomplete filling process, as moisture could remain trapped inside, leading to uneven weight distribution or insufficient ballast.
