Will the wheel hub become hot after running more than ten kilometers?

Running more than ten kilometers will cause the wheel hub to become hot. Below is relevant information about wheel hubs: Introduction: The wheel hub is the rotating part of the wheel steel inside the tire connected by columns to the wheel core, which is the metal component mounted on the axle that supports the tire. It is also called the rim, steel ring, or tire ring. Wheel hubs come in various types based on diameter, width, forming method, and material. Types of Wheel Hubs: The wheel hub is also called the rim. Depending on the characteristics and requirements of different vehicle models, the surface treatment process of wheel hubs will adopt different methods, which can be roughly divided into two types: painting and electroplating. For ordinary vehicle models, the appearance of the wheel hub is less considered, with good heat dissipation being a basic requirement. The process mostly involves painting treatment, which means spraying first and then baking, making it cost-effective with bright and long-lasting colors. Even if the vehicle is scrapped, the color of the wheel hub remains unchanged.
I've been driving for many years, and it's normal for the rims to get slightly warm after running a dozen kilometers. During driving, the braking system generates heat through friction, which is transferred to the rims, especially after frequent braking in urban areas or high-speed sections. I've touched the rims after several long-distance drives, and they felt warm but not scalding. This is mainly because the brake pads and discs generate heat during operation, which gradually spreads to the rims. If the weather is hot or road conditions are poor, heat accumulation can be more noticeable. However, if the rims become excessively hot, it might indicate an issue with the braking system, such as brakes not fully releasing or foreign objects stuck. Regular checks on the brakes and rims can prevent accidents. I once saw a friend's car overheating due to brake drag, which turned out to be a brake fluid issue—timely repairs fixed it. In short, under standard driving conditions, the heat is within safe limits, but don't ignore signs of abnormal temperature rise.
I just started learning to drive not long ago. After driving over ten kilometers, I curiously touched the wheel hub and found it a bit warm, which made me worry if there was a problem. Later, I asked some experienced drivers, and they said this is especially common in summer. When the brakes are working, friction generates heat, and it's normal for the heat to transfer to the wheel hub. I usually drive in the city with frequent stops at traffic lights, so the wheel hubs tend to get warm. However, if the heat is excessive or scalding, it might indicate that the brakes are stuck or malfunctioning, and immediate inspection is needed. Now, I habitually check the wheel hub temperature after long trips without overreacting. Remember, normal heat doesn’t affect safety, but avoid touching it directly for too long to prevent burns. During seasonal maintenance, I also remind mechanics to pay attention to the brake system to prevent minor issues from becoming major problems. Overheating of the wheel hub often starts with slight warming, so regular observation is sufficient.
