What is Tire Fluid, and How is it Used in Tractors?

Tire fluid isn’t a single substance, but rather a range of products used in tractor tires for different purposes. It is typically a liquid solution that is added to the tire to increase its weight, improve traction, and prevent slippage.

What is Tire Fluid?

The amount of tire fluid added to a tractor tire can vary depending on the tire size and manufacturer’s recommendations, but it is typically between 20% to 40% of the tire’s total volume. This means, for example, if a tractor tire has a volume of 20 gallons, it may require approximately 4 to 8 gallons of tire fluid.

The fluid is usually added through a valve stem or other access point in the tire, and once added, it distributes evenly within the tire cavity, providing the desired benefits for tractor operation.
