Electric Vehicles Tire and Pollution Threat.

Electric vehicle industries have grown so much in the past few years and are predicted to keep growing at a high rate in the future, according to a report by Fortune Business Insight, In 2023 alone, the electric vehicle industry is valued at approximately $577 billion. This electric vehicle market is predicted to reach a valuation of $2,108.8 billion by 2033 with a compound annual growth rate (CAGR) of  23.42% from 2024 to 2033.

One key driver of this growth is the drop in the price of EV batteries. Dropped from $1,200 per kWh to $132 per kWh over the past decade, enabling EV production costs more affordable. The adoption of regulation in some countries to subsidies EVs to promote the EVs adoption is also a major factor in this EVs massive market growth

Like any other car, EV cars also need tires as an important part. For tire manufacturers, producing a perfect tire that meets the performance and durability requirements of a vehicle is a mandatory task. Due to some properties of EV vehicles such as their great weight, and large torque, EVs need a specific tire that could meet their requirements.

Why Does EV Need a Special Tire?

When you replace an Electric Vehicle tire with a normal tire you will see a big drop in range. EV tires were designed to maximize their efficiency. EV tires produce a lower rolling resistance. Rolling resistance is the combination of forces that work against the forward motion of your vehicle. Designed to lower rolling resistance meaning the tire creates less friction when rolling. With less friction, EV uses less power to move.

There are a lot of factors that affect rolling resistance such as air pressure, diameter, and width of a tire, and the tread design. But the biggest factor that affects the rolling resistance is its material. The tire compound itself has several types. Some rubber compounds create more grip, some better or wet surfaces, some are hard, and some are softer

Tires and Pollution

With cars, the focus tends to be on air pollution from the car exhaust. But with EVs, this issue is not a problem anymore but rather tires that contribute to pollution significantly. Tires will tear down over their uses, the smallest pieces of this then will go into the air and could be inhaled. According to a report by Emission Analytics, a single car could shed as much as 4 kilograms per year. Add the global car existence, and this number will add up to 6 million tons each year.  

Environmental Hazard

Tires contain several volatile compounds such as microplastics and 6PPD. 6PPD is used to prevent rubber from cracking. 6PPD is also water-soluble, so it is carried off of roads by rain and washed into rivers and oceans. This compound is linked to mass salmon and trout die-offs. Recent studies found that 6PPD is absorbed by plants like lettuce which we usually eat.
