Is it normal to have disc and wheel nuts hot after driving?

Yes, it's normal for disc brakes and wheel nuts to become hot after driving, especially after heavy braking or during prolonged use. The heat generated is a result of friction between the brake pads and discs, as well as the wheel nuts being affected by the heat from the brakes and the wheel itself. However, if they are excessively hot or if there are signs of damage or unusual wear, it may indicate a problem that should be inspected. Regular maintenance and checks can help ensure everything is functioning properly.
