Hello Forumian, I did a new used one 2 weeks ago *FREU* But when I put down winter tires yesterday and put the summer tires/alus on them, it was sobering: the summer tires (4mm profile) are running louder than the winter tires (relatively new). Could it be that the storage at the previous owner caused an imbalance? At higher speeds, the steering wheel moves a little up and down (or left and right if you want to) ), which then feels like a vibration (with the winter tires there was GAR NIX to feel). At about 50-60 I hear a “singing” of the (or a (?)) tire. I was then this morning at the tyre dealer around the corner. The caressed gently over my tires (parked car) and then noted expertly (?): DEFORMATION. He feels bump-shaped changes of the tire surfaces. That is well known especially with the combos (whether BMW or Mondeo, Passat or AUDI A4/A6) against En (End of a tire life at 4mm ??? Hey, I wanted to drive them this summer, , ). To test for unbalance he only waved off , , , he would see what that would be , , , , , and then wanted to sell me directly also new MICHELIN PREMACY for 150€ . “With these things would not happen ! ” What does my description sound like for you ? How can I (from the driving feeling ) distinguish imbalance and deformation ? Why deform combine vehicles R What to do,,,,,,? Rejoice me about clues ! Thanks DC
