Hello, I drive a Passat 3C Variant TDI with 140hp. 10 days ago I had two new full-year tires from Hankook (Optimo 4S) installed on the front, the two GJs from Goodyear are still on the rear. I find from the beginning of the tyre exchange that at a speed of almost 100km/h and at approx. 110km/h a resonance frequency is created, which generates an ugly buzz in the vehicle interior. With the cruise control I can adjust the speed and the sum This sounds like I’m pumping up the tunnel tire on the mountain bike and boarding it over the asphalt. At low speeds it’s absolutely quiet, at higher speeds I can’t say anything yet, because I haven’t driven a motorway yet. You can also notice that the profile blocks really want to bite into the asphalt, this makes itself unbelievably noticeable on the steering wheel. drivages with the new Hankook tire already made, or is it because of the combination tire – vehicle? Can the tire also be installed incorrectly? What reasons can still exist? Thank you for your reports. Until then, chhi-ing
