Have you ever seen a massive truck driving down the highway with one row of tires hovering a few inches above the ground? In this video, we explain the engineering, physics, and laws behind these "lift axles" step by step using real examples and verified mechanical facts.
Why Do Some Truck Tires Not Touch the Ground? | Simple Things Surprising Histories
This documentary style episode from Simple Things Surprising Histories covers the reasons why heavy-duty trucks use retractable wheels, technically known as lift axles, and how they change based on load and location.
Topics covered in this video:
• Why some truck wheels spin in the air (The Ghost Wheel)
• Understanding road damage and axle weight limits
• How weight distribution works on asphalt and concrete
• The mechanics of Lift Axles (drop axles)
• Rolling resistance and fuel economy savings
• How toll costs are calculated based on axles
• Tire "scrubbing" and steering geometry
• The difference between Pusher Axles and Tag Axles
• How trucks prevent tire damage during tight turnsThis video is designed for auto enthusiasts, curious minds, and general audiences who want a clear explanation of heavy vehicle engineering without unnecessary complexity. All explanations are factual, educational, and suitable for learning purposes.
