What liquid are tractor tires filled with?

Polyurethane foam enters the tire in liquid form, but then hardens. The great attraction is that the weight of the ballast increases by up to 50 percent compared to running water. When filling tractor tires with polyurethane foam, the tire is not punctured, but it is not possible to make future tire pressure adjustments. 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. Adding a liquid or fluid to tractor tires has been used as a ballast for tractors ever since tractors began using tires. It is one of the easiest and most affordable ways to improve the stability and traction of the tractor. Because tyres are the lowest point on the tractor, filling them with heavier liquid reduces the tractor's center of gravity.

Calcium chloride is generally sold in the form of flakes. It is mixed with water and the solution withstands freezing to around -50°F. Calcium chloride was the go-to liquid for years, but it's known to rust wheels to oblivion. Obtaining the raw material may be an affordable task, but replacing wheels in the future will not be, however, there are people who still use it because it can be cheap and the solution weighs about 40% more than running water.

Personally, I don't suggest calcium chloride, but it's an option. That's something you'll want to add to your list of farm tools and equipment when you're considering what tractor and machinery to buy. To get the weight per tire of the ballast fluid of your choice, simply multiply the gallons per tire of your size by the pounds per gallon of your ballast fluid. Foaming your tires also means that you can't adjust tire pressure or footprint, but likewise, you'll never have to check tire pressure, so it's really a difficult situation.

Keep in mind that tires fill up faster if you occasionally stop the pump, close the manifold inlet valve, and then fully open the outlet valve to remove excess air pressure. We hope it can help you choose the best option for you and the climate of the region in which your tractor operates. 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. In the John Deer sales manual, they provide a table describing the weight of liquid per tire for a 40% fill and a 75% fill.

At a basic level, the ballast in tractor tires, whether in the form of liquid in the tires or in steel wheel weights, provides the tractor with better traction on the rear wheels and reduces the center of gravity and shifts it back to the rear. Filling your tractor tires with water is a great way to maintain their pressure and increase traction. It is also good to learn how to calculate the desired axle weight and tire pressure to ensure maximum tire traction and avoid the impact of unnecessary stresses on the engine, which could eventually cause an expensive mechanical bill. Since tractors are huge vehicles that weigh at least 19,000 pounds, it is to be expected that all four tires on a tractor will also have to be substantial.

Once again, the valve stem should be in the 12 o'clock position, but since I lifted the two rear tires, I can do it easily without moving the tractor. Wheel weights are counterweighted plates mounted on a tractor tire, similar to the gray one in the photo below. 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. The table shows the most common sizes of tractor tires, the number of gallons they contain at a 75% fill level and the number of pounds added when using RimGuard.
