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

When ensuring the safety of tires on a towable RV, inspecting the lug nuts for proper torque is crucial. Properly torqued lug nuts are essential for maintaining the integrity of the wheel assembly, as loose lug nuts can lead to wheel separation, which poses significant safety risks while driving. Regularly checking the torque ensures that the wheels remain securely attached to the RV, preventing accidents that could result from sudden wheel loss.

While other factors, such as tread depth and weather exposure, are important for overall tire performance and maintenance, the immediate safety concern when operating a towable RV is the secure attachment of the tires to the vehicle. A thorough safety inspection should include verifying that lug nuts are tightened to the manufacturer's specifications to ensure safe handling and stability on the road.
