Will the loss of the small iron block on the wheel hub have any impact?

Yes, it will have an impact. You should redo the tire's dynamic balance. The small iron block is used for balancing. Otherwise, the car may become unstable when driving, the tire noise may increase, and the steering wheel might shake when driving at high speeds. 1. The role of the balancing weight: The small iron block on the car wheel hub is a balancing weight installed on the wheel to maintain dynamic balance during high-speed rotation. 2. Principle: Any object has uneven mass distribution in different parts. Under static or low-speed rotation, this unevenness affects the stability of the object's rotation. The higher the speed, the greater the vibration. The balancing weight helps to minimize the mass difference of the wheel to achieve a relatively balanced state.
That thing falling off is actually quite troublesome. I still remember last time when the small metal block on my car's wheel fell off, the steering wheel shook like an earthquake, especially noticeable when driving on the highway. It's a balancing weight, and without it, the tire's dynamic balance is disrupted, directly affecting driving stability—it feels like riding a small boat. Not only is it uncomfortable, but over time, tire wear can worsen, with edges easily wearing unevenly, and fuel consumption might even increase a bit. I think it's better not to risk driving and quickly find a repair shop to redo the dynamic balance test and attach a new balancing weight—it's an inexpensive fix but saves a lot of hassle. Usually, when washing the car or brushing against the curb, be careful to avoid these small metal blocks falling off and causing trouble.
