In 1845, Robert Thomson, a Scottish engineer and entrepreneur, patented the first pneumatic tire, a revolutionary invention that has since evolved into an everyday item. With the rise of electric vehicles, tires have become more important than ever before. While passenger safety remains a top priority, the right tires can greatly impact efficiency and range. As the traditional global tire market is worth over $200 billion and 2.5 billion tires are sold annually, manufacturers are preparing for the shift towards electric cars and the demand for eco-friendly, high-performance tires.
The primary concern for EV tires has been range optimization. According to Michelin, the difference in efficiency between good and bad tires can be as much as 7 percent. This means that a car with good tires can travel 7 percent further on the same amount of energy. To achieve this, manufacturers are experimenting with nanomaterials and bio-based compounds to reduce rolling resistance and improve performance, traction, and durability. However, reducing tread depth to decrease rolling resistance can also lead to decreased longevity and increased noise.
Continental, a company involved in electric motorsport, claims to have found a solution to this problem. They have developed special soft rubber compounds that reduce rolling resistance and noise without sacrificing mileage. Other companies, such as Enso, are also focused on optimizing tires for EVs, aiming to improve efficiency, durability, and pollution.
Speaking of pollution, it has become a growing concern with the rise of electric vehicles. While they produce zero emissions, the tires themselves can still contribute to pollution through the release of particulates. This has led to a push for more eco-friendly tire options and stricter regulations on tire production.
In conclusion, as the world shifts towards electric vehicles, the tire industry is gearing up for a battle to create the perfect balance of eco credentials, performance, and efficiency. With the potential to greatly impact range and reduce pollution, the development of EV tires is crucial for the success of electric cars.
