Revolutionizing Electric Mobility: The Latest Breakthroughs in Tyre Design

Abstract

The increasing demand for electric mobility has brought about significant advancements in tyre design. This paper covers the latest developments in tyre design that cater specifically to the needs of electric vehicles (EVs). EVs have unique performance characteristics that place greater emphasis on tyre requirements like High traction, Wear resistance, Low Cavity & pattern noise, Low Rolling resistance and High load carrying capacity. Hence, the tyre manufacturers have been working relentlessly to create advanced designs that can meet these requirements.

This paper will cover various aspects of tyre design, including tyre cavity, tread patterns, sidewall design, compound & reinforcement design, and various construction techniques. The tyre cavity and tread pattern play a crucial role in the overall performance of an EV. The new tyre cavity with flat tread and adaptive tread pattern are optimized to provide low rolling resistance, pattern noise reduction and enhanced dry and wet traction. Additionally, the use of advanced materials such as high-performance functionalized polymers and high tenacity reinforcements has led to the creation of low rolling resistance, lightweight and durable tyres that can withstand high power, acceleration, and braking torque on driving wheels of EVs. Furthermore, the construction techniques of EV tyres have also seen significant improvements for durability to handle heavy battery packs. In addition, this paper also highlights various enabling technology like the use of foam technology for cavity noise reduction and Sealant technology for Extended mobility.

In conclusion, this paper showcases the recent advancements in tyre design for EVs. The advancements in tyre design have enabled tyre manufacturers to create bespoke designs that cater to the specific needs of each EV model. These developments are crucial in promoting the adoption of electric mobility and improving the overall driving experience for EV users.
