Air pollution: Smoke contains harmful heavy metals, toxic chemicals, and particulate matter
Tire fires are a major cause of air pollution, as the smoke released contains harmful heavy metals, toxic chemicals, and particulate matter. The combustion of large quantities of tires, typically waste tires, produces significant smoke, which carries toxic chemicals from the breakdown of synthetic rubber compounds. This smoke can contain high levels of harmful chemicals such as carbon monoxide, sulfur oxides, volatile organic compounds (including benzene and styrene), dioxins, and various metals. These toxic emissions can linger in the air, causing serious health issues for nearby communities, including skin and eye irritation, chronic respiratory problems, and an increased risk of cancer.
The dense smoke from tire fires can rise to significant heights and travel long distances, spreading air pollution over a wide area. In one notable example, a tire fire in Rhinehart, Virginia, in 1983, produced a plume of smoke 3,000 feet high and nearly 50 miles long, resulting in air pollution deposited in three states. The long duration of tire fires, which can burn for months or even years, exacerbates the accumulation and spread of air pollutants.
Tire fires release hazardous compounds, including gases, heavy metals, and oil. The average passenger car tire can produce over two gallons of oil when burned, contributing to environmental pollution. This oil can flow into nearby water sources, creating additional environmental concerns. Furthermore, the black rubber particles, or charcoal, left behind after tire fires can absorb harmful chemicals from the air, posing a significant environmental hazard if not properly addressed.
The toxic chemicals released during tire fires, such as benzene, xylene, ethylene, and acetone, are particularly dangerous. These compounds have been linked to cancer and birth defects, underscoring the severe health risks associated with air pollution from tire fires. The smoke emitted contains particulate matter, contributing to overall air pollution and posing risks to both human health and the environment.
To extinguish tire fires, smothering techniques using dirt or sand are often employed, as water and foam are typically ineffective in controlling these fires. The difficulty in extinguishing tire fires further prolongs their impact on air pollution, as the release of toxic chemicals and smoke can continue for extended periods.

Water pollution: Oil from burnt tires can contaminate water sources
Burning tires can contaminate water sources in multiple ways. Firstly, tire fires produce large volumes of pyrolitic oil that can flow into nearby water bodies, such as streams, and cause water pollution. The oil can also ignite, increasing smoke emissions close to the ground level and further spreading pollutants. The smoke from tire fires contains toxic chemicals and heavy metals, which can settle on the ground and be carried to water sources through rainwater runoff. These toxic particles can then leach into the groundwater and spread to new areas, contaminating both groundwater and surface water sources.
The average passenger car tire can produce over two gallons of oil when burned, and for every million tires consumed by fire, approximately 55,000 gallons of runoff oil can pollute the environment if not contained and collected. This oil contamination has significant environmental and health impacts. It can affect aquatic ecosystems and pose risks to human health through drinking water sources.
In addition to the oil released during tire fires, the ash generated from burning tires can also contaminate water sources. The toxic substances in tire ash can be deposited onto the ground and carried by rainwater into nearby water bodies, leading to water pollution.
The toxic chemicals released during tire fires, such as benzene, xylene, ethylene, acetone, carbon monoxide, sulfur oxides, and heavy metals, can also have indirect effects on water sources. These chemicals can mix with rainwater and be absorbed into the soil, eventually making their way into groundwater and surface water.
Furthermore, the particles emitted from tires during their use and wear contribute to microplastics in urban runoff, which can enter water bodies and act as a source of toxic substances. The chemicals and compounds found in tires, such as 6PPD, a chemical used to prevent cracking and degradation, can be toxic to aquatic life. For example, researchers found that coho salmon placed in water containing particles of new and old tires died due to the chemicals leached into the water.

Soil pollution: Hazardous solid waste, such as black rubber particles, can be left behind
Tire fires are a major cause of soil pollution, with hazardous solid waste left behind in the form of black rubber particles, or charcoal. Charcoal is a porous material that absorbs harmful chemicals from the air, and if left untreated, it can become a significant environmental hazard. The ash generated from burning tires can contain toxic substances, including heavy metals, that contaminate nearby soil and water bodies. When tire ash is deposited on the ground or carried away by rainwater, it can leach pollutants into the soil, potentially affecting ecosystems and posing risks to human health through the food chain and drinking water sources.
The average passenger car tire is estimated to produce over two gallons of oil when burned. This oil can exude into the ground and surface water, polluting the environment. In some cases, this may trigger Superfund cleanup status, requiring the intervention of the EPA or other agencies. For every million tires consumed by fire, about 55,000 gallons of runoff oil can pollute the environment unless contained and collected.
Tire fires can also release toxic chemicals into the atmosphere, which eventually settle on the ground in other areas, causing soil pollution. These chemicals include carbon monoxide, sulfur oxides, volatile organic compounds, dioxins, benzenes, and various metals. The smoke produced by tire fires can carry these harmful particles long distances from the fire, and when it rains, they can leach into the soil and groundwater.
The environmental impact of tire fires is significant, and the cleanup costs are high. The EPA, states, municipalities, and private companies have spent millions of dollars cleaning up tire fires and their resulting pollution. The pollution from tire fires can affect entire communities, requiring neighborhood evacuations and long, drawn-out fire extinguishing operations.
