What aspect of tires on a towable RV should be inspected for safety?

Inspecting lug nuts for proper torque is crucial for ensuring the safety and functionality of tires on a towable RV. Loose lug nuts can lead to wheel detachment while driving, resulting in dangerous situations. Proper torque ensures that the lug nuts are securely fastened, allowing the tires to maintain their connection to the wheel hub under various driving conditions.

Additionally, while aspects such as tread depth and weather exposure are important for tire performance and safety, they do not directly relate to the immediate structural integrity of the tire mounting. Evaluating the sidewall color may be relevant for aesthetic purposes or indicating specific tread features, but it does not provide information on the safety or security of the tire itself. Therefore, focusing on lug nut torque is a priority for anyone assessing the safety of tires on a towable RV.
