As the adoption of Electric Vehicles (EVs) continues to grow, the automotive industry has recognized that there are tyre requirements around electric vehicles that differ from that of the Internal Combustion Engine (ICE) Vehicles. These differences are critical for ensuring optimal performance, safety, and efficiency in EVs.
Key Considerations for EV tyres:
- Increased Weight: EVs generally have a heavier battery pack, which places greater demand on tires to support the additional weight.
- Enhanced Acceleration and Deceleration Forces: EVs tend to have higher torque and faster acceleration, which increases stress on tires, requiring them to be more durable and responsive. In addition, the influence of regenerative braking has impact on tyre longevity also.
- Noise Cancellation: EVs are typically quieter than ICE vehicles, meaning that tire manufacturers need to focus on reducing road noise to improve ride comfort.
- Lateral Forces: With increased curb weights, EVs require tires that can handle higher lateral forces during cornering without compromising stability.
- Reduced Rolling Resistance: To maximize battery life and range, EV tires must be designed to minimize rolling resistance, which can directly impact efficiency.
In addition, it is not common to have a spare wheel in an EV and Runflat Tyres are not traditionally OEM on EV’s. The above speaks to the conversation that says – there are critical differences between ICE and electric vehicles that tyre manufacturers need to consider when it comes to designing tyres ensuring they are optimised for electric vehicles.
