Windshield Washer Fluid as Tire Ballast: Cheap, But at What Cost?

When it comes to tire ballast, windshield washer fluid might seem like an easy and affordable option. It’s readily available, has a low freezing point, and it has been used for many years as a tire ballast. But beneath the surface, washer fluid may be costing you more than you think.

The Appeal of Washer Fluid

It’s understandable why windshield washer fluid is a go-to choice for some. It’s inexpensive and easy to find at any auto or farm supply store. For small equipment or light-duty use, it can seem like a convenient option.

Hidden Costs and Drawbacks of Windshield Washer Fluid as a Tire Ballast

Despite its convenience, washer fluid comes with serious drawbacks:

• Toxicity: Most washer fluids contain methanol, a toxic alcohol that can be harmful to humans, pets, and the environment.

• Low Weight: Windshield washer fluid is not heavy compared to other ballast alternatives, weighing in at only 7.6 pounds per gallon. It is even lighter than water. That means less traction, less stability, and reduced performance of the equipment where washer fluid is installed.  

• Corrosion Risk: While not as corrosive as calcium chloride, washer fluid still contains chemicals that can corrode rims and valve stems over time.

Environmental and Safety Concerns for Windshield Washer Fluid

Windshield washer fluid often contains the following materials:

• Methanol (up to 30–40%) – a toxic alcohol

• Ethylene glycol or propylene glycol in some winter blends

• Dyes, detergents, and other additives

Due to these materials and additives, windshield washer fluid leaks can contaminate the ground and water supply. It poses a danger to pets, livestock, and wildlife.  

Some of the greatest risks or concerns if windshield washer fluid leaks from a tire are:

Soil Contamination

• Methanol and glycol compounds can kill soil microbes that are essential for healthy soil.

• The fluid may disrupt nutrient cycling, harming plant growth.

• It can also cause long-term soil toxicity, making the ground unusable for crops or grazing.

Groundwater Pollution

• Windshield washer fluid is highly water-soluble, so it easily leaches into groundwater.

• Methanol can contaminate wells, drinking water supplies, and nearby surface water like streams and ponds.  

• Even small amounts can exceed EPA and state limits for safe drinking water.

Harm to Plants and Vegetation

• Methanol can dehydrate and kill plants  

• If spilled near trees or crops, it may lead to leaf burn, stunted growth, or plant death.

Toxic to Wildlife and Livestock

• Methanol and glycol compounds are toxic if ingested, inhaled, or absorbed through skin.

• Livestock or wildlife that graze on contaminated land or drink tainted water are at risk. This is particularly concerning as animals are often drawn to puddles and collections of water and can become sick or die from exposure.

Sustainability and safety are important as you consider what tire ballast is best to utilize. Using a toxic chemical as ballast is a growing liability.
