Hankook supplied the tyres for the TCR and GT4 classes, including the new BMW M4 GT4, which made its official race debut in the Nürburgring 24 Hour race. 21 cars out of the 160 starters ran on with its Ventus Race range; the manufacturer supplied a total of 1,500 tyres for the Eifel region event. Hankook states that the slick tyre provided a consistently high level of grip both in daytime track temperatures of up to 47 degrees and on a cooler track during the night. The manufacturer added that the tyres’ high level of consistency allowed drivers to clock fast lap times at the end of their stints.
