Tractor tires are often filled with a calcium chloride solution to provide ballast, improve traction, and reduce tire and machinery wear. This dense, widely available, and competitively priced salt solution can add up to 30% more weight than water and lower the freezing point of the solution well below that of tap water. A 31 percent calcium chloride blend is freeze-resistant to minus 58 F. Adding air tubes to the

Calcium chloride weighs 11.3 pounds per gallon, making it a good choice for getting the most weight out of your tractor. If a tire breaks and causes liquid ballast to leak, the salt is not toxic to animals, but it can damage any plant that grows on the affected soil. Nebelsick plans to move away from calcium chloride due, in part, to the mechanically assisted front-wheel drive tractor. However, 60% of farmers in the Nebelsick market still use liquid ballast, in their case, a premixed saline solution that is approximately half as corrosive as calcium chloride.
Filling tires with polyurethane foam is an alternative option, but it does not allow for future tire pressure adjustments.When filling
