Pre-Trip Inspection for Commercial Motor Vehicles (CMV)

What are the four main items to check for when pre-tripping the wheels on a CMV? The four main items to check for when pre-tripping the wheels on a CMV are tire pressure, tread depth, lug nut tightness, and valve stem condition.

Pre-Trip Inspection for CMVs

When conducting a pre-trip inspection for Commercial Motor Vehicles (CMVs), it is crucial to pay close attention to the condition of the wheels. Here are the four main items to check for:

1. Tire Pressure:

Checking the tire pressure is essential to ensure that the tires are properly inflated. Improper tire pressure can lead to a higher risk of blowouts and poor vehicle handling. It is important to refer to the manufacturer's recommended tire pressure levels.

2. Tread Depth:

Inspecting the tread depth of the tires is important for traction and grip on the road. Worn-out tires with insufficient tread depth can increase the chances of skidding and losing control of the vehicle. Replace tires that have worn down beyond the recommended tread depth.

3. Lug Nut Tightness:

Ensuring that the lug nuts are securely tightened is crucial for preventing wheel detachment while driving. Loose lug nuts can lead to wheel separation, posing a severe safety hazard. Use a torque wrench to tighten the lug nuts to the manufacturer's specifications.

4. Valve Stem Condition:

The valve stems are vital for maintaining proper tire inflation. Inspect the valve stems for any signs of damage or leaks. Faulty valve stems can result in gradual air loss from the tires, affecting stability and performance.

By thoroughly checking these four main items during the pre-trip inspection, drivers can enhance the safety and reliability of CMVs on the road.
