 They checked them out for handling, noise, and energy efficiency, and they came up with the best overall tires, the most energy efficient, the least energy efficient, the best overall performance, and then the best balance of performance and efficiency. I will link up that report on the website richontech.tv, but spoiler alert, the Michelin Pilot Sport 4S non-EV was the best overall, but the most efficient was the Hankook.
