How to Solve High-Speed Vibration in BMW 525?

[McMadison]

BMW generally uses run-flat tires, which contain steel wires inside. After prolonged parking, the steel wires in the tires that are in contact with the ground can become rigid, leading to tire deformation. For example, if the tire pressure of the four tires is uneven—some high and some low—or if the tire pressure is too high, vibration may occur at high speeds. When performing wheel balancing, remove the tires and check if the rims are wobbling. If they are, it’s likely that the rims are deformed. Under dynamic conditions of the wheel, weights are added to the wheel to correct the balance of each edge. This process is called wheel balancing.
