Why is it important to torque wheel lug nuts properly?

Torqueing wheel lug nuts properly is crucial for ensuring wheel safety and performance. When lug nuts are tightened to the manufacturer's specified torque, it secures the wheel firmly to the hub. This prevents the wheel from coming loose while the vehicle is in motion, which can lead to accidents or loss of control. Additionally, proper torque helps to distribute the load evenly across the wheel and hub, reducing the risk of damage to both components and ensuring optimal handling and braking performance.

The other options do not address the critical safety and functional aspects that proper torqueing provides. While aesthetic appearance, vehicle weight, and legal requirements may be relevant in other contexts, they do not highlight the fundamental necessity of secure wheel attachment, which is vital for safe vehicle operation.
