The Auto Bild 2024 summer tyre test for electric vehicles (EVs) in the 235/55 R19 size aimed to compare the performance of standard and specialized EV tyres to determine if EV-specific tyres offer significant advantages over their conventional counterparts. The test included eight tyre models: the Continental PremiumContact 7, Falken e.Ziex [ev specific], Hankook iON evo SUV [ev specific], Michelin Pilot Sport 4 SUV, Goodyear Eagle F1 Asymmetric 6, GT Radial SportActive 2 EV [ev specific], Bridgestone Potenza Sport, and Goodride ZuperEco Z-107.
Interestingly, Michelin decided not to officially enter their EV-specific tyre, the Pilot Sport EV, or their e-Primacy model in the test, opting instead for the Pilot Sport 4 SUV from their sports tyre segment. Despite this, the discontinued Pilot Sport EV was still tested alongside the other contenders, providing an opportunity to compare its performance against both standard and EV-specific tyres.
The tyres were evaluated on a Kia EV6 electric vehicle across three main categories: Wet Performance (40% weightage), Dry Performance (40% weightage), and Cost (20% weightage). Wet Performance tests included aquaplaning, curved aquaplaning, handling, steering response, and braking. Dry Performance assessed handling, braking, rolling comfort, and pass-by noise. The Cost category considered mileage, price per mileage, rolling resistance, and electricity consumption.
In the final results, the Michelin Pilot Sport 4 SUV emerged as the overall winner, receiving an "Exemplary" rating. The Continental PremiumContact 7 and Hankook iON evo SUV tied for second place, also with "Exemplary" ratings. The Goodyear Eagle F1 Asymmetric 6 followed closely in fourth place. The test demonstrated that while specialized EV tyres like the Hankook iON evo SUV can offer benefits, high-quality standard tyres such as those from Continental and Michelin can also provide excellent performance on electric vehicles.
As for the Michelin Pilot Sport EV, although it wasn't officially part of the test, its performance in the measured categories suggests it would have likely placed in the lower half of the rankings. The tyre struggled in wet conditions, placing 7th in braking and 8th in both aquaplaning tests. It fared slightly better in dry handling, securing 6th place. However, without complete data across all test criteria, it's difficult to determine its exact position in the final order.
The Auto Bild 2024 summer tyre test for EVs showcases the importance of considering a balance of safety, performance, and efficiency when selecting tyres for electric vehicles. While EV-specific tyres can offer some advantages, the test proves that high-quality standard tyres can also rise to the challenge of providing excellent performance on these technologically advanced vehicles.

The rolling resistance and energy consumption tests yielded intriguing results, particularly for the Bridgestone Potenza Sport and GT Radial SportActive 2 EV tyres. In the rolling resistance test, the Bridgestone Potenza Sport had the highest rolling resistance, while the GT Radial SportActive 2 EV performed well, ranking second only to the Falken e.Ziex.
However, the real-world efficiency test revealed a different picture. The GT Radial SportActive 2 EV, despite its low rolling resistance in the lab test, consumed the most energy during real-world testing. This discrepancy highlights the importance of conducting both laboratory and real-world assessments to gain a comprehensive understanding of a tyre's performance.
The article does not provide specific theories to explain this discrepancy, but it is possible that other factors, such as the tyre's construction, compound, or interaction with the road surface, may have contributed to the GT Radial SportActive 2 EV's higher energy consumption in real-world conditions.
