EV tire compounding challenges and approaches

Electrification in the passenger vehicle (PV) is in increasing trend. The CV segment is expected to follow in the footsteps of PV. The conventional requirement of rolling resistance, traction and mileage for an IC engine vehicle is no longer good enough to meet the performance requirements of an EV. Though not exclusively mentioned, low noise and high cut and tear resistance became essential requirements of EV tires due to the combined effect of low hysteretic tread compound and tires designed for high traction. In this current work, the compounding challenges and approaches to tackle the expanded and conflicting performance requirements will be discussed to achieve the optimized set of tire compound properties.
