The Future of Driving: How Eco-Friendly Tires are Making a Difference
With engines going electric and alternative fuel sources growing in popularity, the eco-friendly green wave has fully engulfed the car industry. But the engine is only one part of the car. A significant component that requires replacing is the humble tire. Tire manufacturers are using three main methods to do their part in saving the environment and making eco-friendly tires.
In today’s age of conscious consumption, eco-friendly products are making their mark in every industry, and the tire market is no exception. As the world strives to reduce its carbon footprint, introducing eco-friendly tires is a testament to the industry’s commitment to a greener planet. But what exactly are eco-friendly tires, and why should they be on your radar?
What Makes a Tire Eco-Friendly?
Unlike traditional tires, eco-friendly ones are designed with the environment and performance in mind. They are typically made from sustainable materials, including recycled or renewable materials like dandelion rubber. Furthermore, their production processes are designed to minimize waste and reduce energy consumption.
Benefits of Eco-Friendly Tires
- Lower Rolling Resistance: These tires are engineered to reduce the energy they use, translating to better fuel efficiency for your vehicle.
- Durability: Eco-friendly tires often come with improved wear characteristics, ensuring they last longer and reduce the frequency of tire replacements.
- Reduced Carbon Footprint: From production to performance, these tires ensure minimal environmental impact, making them a top choice for the eco-conscious driver.
Tire Construction
The first key component of an eco-friendly tire is the raw material used. Companies attempt to replace rubber with a synthetic blend, often incorporating silica. Silica can not only help replace rubber in the treads but reduces road friction – which we’ll come back to in a moment.
The tire’s construction, from treads to sidewalls, is also essential in keeping the tire green. Stiffer sidewall construction reduces the heat generated by the tire, which contributes to the tire’s longevity.
Aside from rubber, companies are also investigating ways to reduce the amount of petroleum used in creating a tire. Between 5 and 10 gallons of petroleum oil make a single tire, which the industry has been trying to cut back or eliminate for over 20 years.
Making synthetic rubber is also hard on the environment, leading manufacturers to try to cut synthetic rubber usage in half. Carbon black is used as filler for treads, though, as mentioned, silica is increasingly prevalent as a replacement.
More sustainable plant-derived materials are making headway as substitutes for various tire components, such as sunflower oil instead of petroleum and flora-derived latex replacing rubber. Even oil derived from orange peels has been used instead of more toxic chemicals.
Rolling Resistance
As mentioned, silica helps reduce rolling resistance or energy loss as the tire deforms against the road. Conserving energy also increases fuel efficiency. Rolling resistance accounts for 10-15 per cent of fuel consumption in passenger cars but can be as much as 30 per cent of fuel usage in large trucks. While low rolling resistance tires may only reduce that by 2 to 3 per cent, it’s still fuel savings – not only helping the environment but your wallet, as well.
Keeping your tires inflated near the recommended inflation level, it should be noted, can also help in saving fuel. The second benefit, a byproduct of how efficient the car is running, is reduced CO2 emissions.
Low-rolling resistance tires have improved significantly since they were introduced, providing good all-around performance, and most manufacturers offer low-rolling resistance tires.
Wear and Tear
The tread – often a proprietary pattern unique to a manufacturer – makes a great deal of difference in how quickly a tire will wear down. For example, a winter tire used in summer will wear down quickly. The tire composition and tread are not made for summer driving and will be rendered unusable much faster than in colder conditions.
As noted above, materials contribute to the tire’s lifespan, and what goes into treads can also help leave less proverbial rubber on the road. As tread patterns continue to develop and what the treads are made of improves, tires will see better rolling resistance and less wear, with better durability and longevity–meaning longer times between replacements. Fewer replacements directly equate to fewer tires needed, cutting down on materials required for manufacturing.
Building a Better Tire
Let’s look at an example of how construction, rolling resistance, and durability go into making a tire. Hankook tires feature the company’s “Kontrol technology,” which was introduced in 2008. The aim is to improve “performance, safety, and comfort” and make eco-friendly tires.
The “k” in “Kontrol” stands for “kinetic,” the company says, which ties into rolling resistance. Not only is Hankook focused on reducing what it calls rotational resistance, but they use silica in its treads.
The eco-friendly materials used do not stop at silica, however, as Hankook is replacing oil byproducts like synthetic rubber, carbon black, and synthetic oil.
On top of making the tire itself eco-friendly, Hankook is improving the manufacturing process by purifying water contaminants produced as byproducts and minimizing greenhouse gas emissions.
Like other manufacturers, they work hard to ensure that eco-friendly does not mean a sub-par tire, focusing attention on how the tire vibrates, grips the road, wears, and even how much noise the tire produces.
Tire companies are cutting down on using materials harmful to the environment while reducing friction, thus increasing fuel efficiency. As a result of less fuel used, CO2 emissions are also reduced, and the car becomes greener.
With less wear on the tire, durability and longevity are extended, meaning fewer trips to replace tires. Tire manufacturers don’t have to produce as many tires, saving materials and the energy needed to create the tires. In the end, manufacturers can provide high-quality, eco-friendly tires.
