Ev Trend Dominates Tyre Development

Ev Trend Dominates Tyre Development

The global electric vehicle (EV) market has taken a tremendous leap forward, with new registrations reaching record market shares in nearly all countries. For the tyre development landscape, the accelerating growth of the EV market means a pervasive transformation.

Boosting circular economy

At Black Donuts, the impact of the EV trend can be seen everywhere, from the tyre designers’ desks to the new practices of tyre testing. Beyond meeting new demands of the EV sector, the procedures and practices are tuned to serve the company’s strategic goal: to spearhead the industry’s shift towards a circular economy.

Black Donuts launched the first EV tyre development projects with its tyre manufacturer customers in 2018. The internal research on EV tyres was initiated even before, at the time of the first EVs entering the market. “The first research project addressed the primary technological challenges: rolling resistance and noise,” says lkka Lehtoranta, Head of Tire and Material Development at Black Donuts.

In tyre design, it is essential to focus on specific aspects to ensure optimal performance for electric cars. Compared to combustion cars, tyres for Evs must carry a heavier load withstand high instant torque – and be efficient and quiet. 

Lately, the focus on tyre technology has shifted towards more comprehensive sustainability. Bio-based materials and compounds are opening new possibilities, and the rapid growth of the EV market accelerates the pace of development. ”The EV trend has highlighted the sustainability of tyres. The demand for bio-based materials and tyre recyclability has significantly increased,” says Jarkko Mällinen, Technology Development Manager of Black Donuts.

In cooperation with its partners, Black Donuts is investigating new possibilities to replace fossil-fuel-based raw materials with bio-based or renewable materials in all products, including studded tyres. The company is currently testing the use of bio-based plastics in stud bodies.

Also, end-of-life tyres are a hot topic in the industry, and Black Donuts is researching how the waste tyres can be recirculated and recycled back into the process. Even the tyre development process is undergoing a renaissance. New design tools for faster tyre development are being introduced, emphasising the key features of sustainable, future proof tyres.
