Does the weight affect the smooth rotation of small wheels?

Driving a vehicle with severely unbalanced wheels for a long time can also affect the lifespan of the bearings, and prolonged use may lead to bearing fatigue. Causes of wheel imbalance: Mainly due to external forces such as collisions, compression, etc. Additionally, low tire pressure can easily cause wheel deformation. Generally, iron wheels are more prone to deformation, while aluminum alloy wheels fare better. The tire is also a critical factor—some tires have uneven thickness, which makes them inherently unbalanced. After inflation, the uneven thickness causes the inner diameter to deviate from a standard circular shape, which over time affects the wheel's shape and leads to imbalance. Phenomenon of rear wheel wobbling: During normal driving, the rear wheels sway from side to side. This side-to-side movement accelerates the wear of bearings and tires, while also increasing power loss from the engine.
Small wheels not turning smoothly is often directly related to weight issues. As a mechanic, I've encountered numerous cases where excessive load on bearings or pulleys dramatically increases rotational resistance, causing jamming or stiffness. Overweight conditions accelerate component wear and compromise lubricant effectiveness. For instance, trunk-mounted pulleys become immobile when overloaded. The solution is straightforward: first reduce the load and inspect for wheel looseness or deformation; then clean and reapply grease. Persistent issues likely indicate bearing failure requiring replacement. Regular load monitoring and preventive maintenance can prevent major repairs. Never underestimate this - neglect accelerates systemic component degradation.
