i have Summit 2015 and on 100 speed you feel with the noise sound for the road ,it's not comfortable at all .
it's 100 km/h only on the high way
i have changed them already with best tires at all Pirelli Scorpion and still . just if the pavement was new i noticed it become smooth . but the air sound against the car or i mean the hitting sound on the car also .
yes it is like helicopter noise. but the windows are all closed . and i have replaced them also from the dealer. but it still this sound .
many many thanks to you for your answers i really appreciate your support here .
