Interestingly, Michelin decided not to officially enter their EV-specific tire, the Pilot Sport EV, or their e-Primacy model in the test, opting instead for the Pilot Sport 4 SUV from their sports tire 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 tires.
The tires 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 tires like the Hankook iON evo SUV can offer benefits, high-quality standard tires 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 tire 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 tire test for EVs showcases the importance of considering a balance of safety, performance, and efficiency when selecting tires for electric vehicles. While EV-specific tires can offer some advantages, the test proves that high-quality standard tires can also rise to the challenge of providing excellent performance on these technologically advanced vehicles.
Dry
The Hankook iON evo SUV showcased the best dry braking performance, stopping just short of the Continental PremiumContact 7. The GT Radial SportActive 2 EV and Goodride ZuperEco Z-107 required the longest distances to come to a halt.
Continental PremiumContact 7 demonstrated the most agile and precise handling on dry roads, closely followed by the Michelin's Pilot Sport 4 SUV and Bridgestone Potenza Sport. The Goodride ZuperEco Z-107 and GT Radial SportActive 2 EV struggled to keep up with the leaders in this discipline.
Wet
In wet braking tests, the Continental PremiumContact 7 outperformed the competition, with the Goodyear Eagle F1 Asymmetric 6 and Michelin Pilot Sport 4 SUV not far behind. The Goodride ZuperEco Z-107 had the longest braking distance on wet surfaces.
The Bridgestone Potenza Sport and Michelin Pilot Sport 4 SUV displayed the best handling characteristics on wet roads, while the Goodride ZuperEco Z-107 was again last.
The Michelin Pilot Sport 4 SUV had the highest resistance to aquaplaning in straight-line conditions, with most tires performing similarly well. The Falken e.Ziex was the first to lose grip on the water-covered surface.
Comfort
The Hankook iON evo SUV proved to be the quietest tire, whereas the Bridgestone Potenza Sport produced the most noise.
Value
The Continental PremiumContact 7 demonstrated the lowest wear rate, promising the highest mileage. The Bridgestone Potenza Sport had the highest wear, just half of the Continental.
The rolling resistance and energy consumption tests yielded intriguing results, particularly for the Bridgestone Potenza Sport and GT Radial SportActive 2 EV tires. 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 tire's performance.
The article does not provide specific theories to explain this discrepancy, but it is possible that other factors, such as the tire'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.
The Continental PremiumContact 7 produced the least amount of tire abrasion, suggesting a more environmentally friendly performance. The Bridgestone Potenza Sport had the highest abrasion rate, which may lead to increased tire particulate emissions.
