Is it normal for the front wheel hub to be hot to the touch?

[DiTheo]

Under normal circumstances, the wheel hub should not be hot to the touch. However, after prolonged driving, the brake pads and tires may become quite hot. The wheel hub is the rotating part of the wheel that connects the tire's inner rim to the wheel center via spokes. It is the metal component that supports the tire and mounts onto the axle, also known as the wheel rim, steel rim, or simply the wheel. The wheel hub contains information such as size, width, PCD (Pitch Circle Diameter) and bolt pattern, offset, and center bore. Reasons for a hot wheel hub: 1. Heat generated from prolonged friction between the tire and the road surface; 2. High temperatures caused by extended braking and friction from the brake pads; 3. Leakage in the brake caliper or brake fluid lines; 4. Overly tight or abnormally worn bearings.
