Why are tractor tires filled with calcium?

Calcium chloride solutions are used in tractor tires and other off-road tires to provide ballast, improve traction and reduce tire and machinery wear. Calcium chloride solutions can add approximately 30% to the weight of water and lower the freezing point of the solution well below that of tap water. There are three main reasons to fill tractor tires with liquids, such as water. It will increase the traction of the rear tires, reduce the center of gravity and prevent the rear tires from lifting off the ground when lifting heavy objects or by adding bucket loaders and other accessories to the front of the tractor.

Calcium chloride is a dense, widely available, competitively priced, but highly corrosive salt solution. You must add air tubes to the tractor wheels with %26 tires, otherwise the steel wheels will corrode quickly. A 31 percent calcium chloride blend is freeze-resistant to minus 58 F. 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. There are several other methods for adding ballast to your farm tractor that are just as effective, if not, more effective than water. Wheel weights are counterweighted plates mounted on a tractor tire, similar to the gray one in the photo below. Tractor dealers are often best placed to advise you on the exact amount of ballast your tractor needs, the right formula for the local climate, and the best way to protect the life of your tractor's wheels and tires.

When removing the ballast, whether wet or dry, be sure to maintain the proper weight distribution of the tractor on the front and rear axles. I am sure that it was through trial and error that they were able to find these effective and successful compounds and fluids to weigh down the tires of their tractors. Usually, this is 25% in the front and 75% in the rear on two-wheel drive tractors, 40% in the front and 60% in the rear on tractors with mechanical traction, and 55% on four-wheel drive tractors. Like the calcium chloride option, it is better for add weight to the tractor than many other liquid ballast options.

In the John Deer sales manual, they provide a table that describes the weight of the liquid per tire for a 40% fill and a 75% fill. The water weighs just 8.3 pounds per gallon, which will limit the amount of weight you can add to the tractor compared to other liquid ballast options. When bucket loaders and other accessories tend to take front tires off the ground, the liquid ballast added to those tires can be particularly useful. We hope it can help you choose the best option for you and the climate of the region in which your tractor operates.

In addition, it's worth noting that once tires are made of ballast, you'll need other types of heavy machinery (such as a forklift) to move, replace, or adjust them. Given the disadvantages of these other forms of ballast for tractor tires, it may be worth considering beet juice for tire ballast. When filling tractor tires with polyurethane foam, the tire is not punctured, but it is not possible to make future tire pressure adjustments.
