Ok, I have a 2010 SPORT Supercharged, but this is what I am running (Since April 2018 )
Hankook VENTUS ST RH06 - SIZE: 275/40R20. I replaced a set of Conti Extreme Contact Sports and I am very pleased. These Hankook tires handle just as good as the Continentals did up to 100+ MPH, have a more aggressive tread - I do take the Sport off road - beach sand mostly and they work a lot better than the street only Contis did. The ride seems more refined as well.
