The car industry is constantly adapting to the technological revolution the sector is undergoing thanks to the growing demand for electric vehicles. This transformation is not just limited to the vehicle’s source of energy, but also affects other aspects of its design and engineering.
In this article, we will explain the characteristics of the tyres used on electric vehicles and their evolution over time.
Rolling resistance and energy efficiency
In order to achieve a greater reduction in carbon emissions, electric cars need to be efficient. And tyres play a major role, because they have a direct effect on the vehicle’s efficiency.
Rolling resistance refers to the energy the vehicle requires to make its tyres move over a surface. The tyres for electric cars are specifically designed to reduce this resistance, thereby helping to increase the vehicle's energy efficiency. This means that electric cars need less energy to keep moving.
Furthermore, tyres for electric vehicles often have a narrower tread than traditional tyres, which helps to reduce resistance and improve energy efficiency. This has a direct effect by causing less wear on the battery.
Better grip
Electric cars can often produce high torque at zero RPM. The tyres designed specifically for these vehicles can offer better grip and adherence, which improves performance in acceleration and manoeuvrability.
Quieter tyres
Another important aspect of tyres for electric cars is noise. Given that electric engines are quieter than internal-combustion engines, the rolling noise becomes more perceptible. These tyres often incorporate technologies that reduce noise emission, which improves the driving experience and reduces noise pollution in urban areas.
Durability and maintenance
Electric cars are heavier than internal-combustion vehicles and their tyres therefore have to bear a greater load. Another challenge for the sector is how to achieve more durable tyres that can handle this wear and tear. Manufacturers are developing composites and structures that resist this erosion, while also maintaining optimal performance.
At Endolla Barcelona, we welcome all technological advances in the electric mobility sector that help us to reduce carbon emissions and create a more sustainable future.
