the faster i went the more it would shake, was there a problem with the installation?
Answer Hisham, I suspect the problem is in the balancing. Most BMW’s have wheel bolts instead of lug nuts. Many tire dealers do not have the proper equipment to balance these wheels properly. The wheels on many of the European cars are balanced from the bolt holes and not the center of the rim. I suspect that the tire dealer balanced your rims from the center. I don’t believe this to be unsafe however, for an optimum balance you would be better served to have the wheels/tires balanced at a BMW service shop or a tire dealer that has the proper equipment.
