Is it serious if the small iron block on the wheel hub falls off?

The small iron block on the wheel hub falling off is not a serious issue. Below is relevant information about the small iron block on the wheel hub: Function: The small iron block on the wheel hub is used for tire dynamic balancing. If it falls off, it needs to be reinstalled by removing the wheel, hammering in a lead block of the corresponding weight at the same position, performing wheel dynamic balancing again, and then reinstalling it. Impact: If it is not replaced after falling off, it will affect the driving comfort of the vehicle. Prolonged driving may lead to vehicle shaking, deviation, abnormal tire wear, and increased safety hazards. The car wheel is an assembly consisting of the tire and the wheel hub. Due to manufacturing processes, the weight distribution of various parts of the wheel is uneven. When the car rotates at high speed, dynamic imbalance occurs, causing unstable driving and steering wheel vibration. To avoid or eliminate this phenomenon, weight is usually added to the side of the wheel to correct the balance of various parts of the wheel.
I've been driving for over a decade and often encounter those small metal blocks falling off the wheel rims - they're actually wheel balancing weights. When they fall off, the wheel becomes unbalanced, causing noticeable vibrations while driving, with the steering wheel shaking severely, especially at high speeds. Over time, this accelerates tire wear and may damage wheel bearings or shock absorbers. Last time I lost one, after just two weeks of driving, the tire tread wore unevenly, costing me a lot of unnecessary money for new tires. It's best to visit a professional shop immediately - they can rebalance the wheel using specialized equipment in just minutes, usually for around 100 RMB. When washing your car, regularly check if these small weights are loose to prevent future problems and save yourself a lot of trouble.
I just started driving not long ago, and once when I was washing my car, I noticed the small metal blocks on the rims were missing. At first, I didn’t know what they were. Later, I learned they were wheel weights, and without them, the wheels become unbalanced, causing the car to wobble, especially when accelerating or turning. The steering wheel shakes, making the ride uncomfortable, and the tires wear out faster, increasing the risk of leaks. I quickly asked a friend to recommend a repair shop, took the car in for a check, and got new weights installed for just over 60 bucks. My advice is not to delay—fixing it early is safer. If you feel excessive vibration while driving, temporarily reducing speed can help alleviate some of the stress.
