Hello, with the change from winter to summer tires I also had the Runflat tires exchanged for Non Runflat tires. Since then I have between 80 and 100 km / h a slight vibration in the steering wheel. After everything I found in the net, this seems to be a balancing problem. So back to the tyre dealer. He has then after the front wheels after. Unfortunately this did not succeed. So once again all four wheels were balanced and the rear ones were made on top of it. L the steering wheel still trembles slightly between 80 and 100 km/h. It is not as strong as at the beginning to feel and not always, but now and then. The tyre dealer says that he can’t do more. Can this be due to something else and if so what or is this normal with the sports suspension? Since the shaking is not so strong and also not always occurs, I also thought about leaving it. I can’t drive constantly to balance. ? My mini is a cooper from 07/05 with sports suspension. He has original Mini-LM rims with 205 / 45 / R17 on it. On Monday the little one must anyway because of the clutch to BMW. Does it make sense to have this checked there? I have often heard that BMW dealers are not so competent in tyre questions and then tell me that I have to make run flat tires on it again. Thank you for your help.
