Hello I bought a day registration. Car stood for over 5 months at the Kia dealer. Tire Nexen Winguard Sport 2 (245/45 R19) The vibrations come from the rear axle. Sometimes you can notice it from 75 and then only from 90kmh. What amazes me. As soon as it vibrates, that does not stop up to 130. With poorly balanced rims I know this so that it is present at about 80, at 90 – 110 is quiet and at 120 it vibrates again. As soon as I drive off the highway and the speed below The driver with ContiSportContact 5 also had slight vibrations during the test drive. Seller said this is due to the 3 bar that the tires have. Picked up the car Friday night. Mail to the seller is already out. What is your guess. Rust on the brake? Rust on the wheel hub? Wrongly balanced? Height stroke? As said, as soon as you drive 60, you think the vibration motor in the seat was removed. Don’t think that the construction is necessary, otherwise a lot of sportage riders would go to the barricades. Moreover, my preface lift Sportage didn’t have that.
