To create an organic garden, you need to choose the healthiest planting methods. Asking if tires are toxic for gardening is crucial before using them. Here, you’ll find the answer!
When I started gardening, using tires was highly recommended. Every DIY website suggested it, and gardening with tires was marketed as a great way to recycle them. I couldn’t help but wonder if they were really safe to use, so I did some research.
In this article, I share what tires are made of and if it’s a good idea to use them for gardening.
What Tires Are Made From
Typically, a tire can contain over 100 components, but I’d like to focus on the harmful ones. There’s a lot of secrecy around the exact materials that go into manufacturing tires, and each brand follows a different structure.
Most tires contain heavy metals, including copper, cadmium, chromium, lead, nickel, and zinc. These metals are harmful to your health. Some complications they can lead to include anemia, cancers, and kidney failure.
Solvents often used to produce tires are benzene, styrene, toluene, and xylene. These have been linked to cancer and other health complications.
Rubber is the main synthetic compound used to manufacture tires. Many brands use natural rubber or a combination of both. Synthetic rubber, which includes butadiene, is a known carcinogen.
Are Tires Toxic For Gardening?
Tires have been widely recommended for gardening, but whether they are safe is still unclear. There are sides approving and disapproving of the use of tires in your garden, and it’s difficult to pinpoint the truth.
Many websites – including health ones – recommend using tires in your garden for both environmental reasons and ease, but few touch on the subject of health.
The facts are that tires contain many chemicals and metals that won’t do us any good if we consume them. Over time, these leach into the environment. The argument against using tires is that these chemicals enter our food when we use tires to grow them, while the argument for using tires states that the leaching process is so lengthy it doesn’t have an effect.
Does this leave us with the question: Are tires toxic for gardening? The short answer is yes. Tires can be toxic for gardening, but how their toxicity truly affects what we grow is open for debate.
The Benefits Of Using Tires For Gardening
Using old tires for gardening has benefits. Besides the fact that you may have some lying around that you didn’t know how to get rid of, these benefits will make you consider using them even more!
Tires make the best no-fuss raised beds, and there are many benefits to planting this way.
- You can plant more in a small area when you use raised beds.
- Elevated soil warms faster and black tires speed this warming effect up even more.
- Planting in tires provides deeper ground for roots to develop.
- Raising beds is beneficial to older gardeners who can’t bend as low.
- The soil in raised beds is more exposed to the sun and wind, which means they have improved drainage.
When the cold creeps in, most gardeners worry about their crops. The black rubber that tires are made from is excellent at locking heat in! During the colder months, your soil will stay warm, and your fruits, veggies, or plants won’t suffer as much.
During heavy rain, your soil will also stay protected.
Is It Safe To Eat Food Grown In Tires?
Plant roots absorb substances from the ground they grow in, and if tires leach chemicals, it’s worrisome to think how much of it is absorbed by what you plant.
As of now, there’s no hard conclusion on whether eating foods grown in tires is safe or not. Vegetables grow relatively quickly, and tires can take years to leach harmful chemicals. Knowing this, it’s safe to assume that eating food grown in tires won’t cause you any harm.
If you’re planting fruit trees, it’s better to keep them directly in the ground. Because they take so long to grow before they start producing fruit, there’s a chance that they can absorb chemicals leached by tires.
With no concrete evidence available, it’s still a guessing game. Many experts say it’s perfectly okay to eat foods grown in tires, and I agree.

Do tires pollute soil?
Yes. Tires pollute soil by leaching chemicals into the ground.

How do tires harm the environment?
Tires don't decompose and release methane gas into the air while sitting in the sun. When exposed to rain or wind, they can start to crumble and spread over a large surface. Tires leach heavy metals into soil and water that contaminates it. If smaller tire pieces end up in the ocean, marine life can eat and die from it. If tires are burned to recycle them, they release oil into the ground and a thick black fog that pollutes the air.
