Why Do Truck Wheels Hang in the Air?

Описание: Why Do Truck Wheels Hang in the Air?

Have you ever noticed a truck driving down the highway with one of its wheels not touching the road at all?

At first glance, it looks like a serious mechanical failure.
A broken suspension.
Or a strange visual glitch.

But that floating wheel is actually doing something incredibly smart.

In this video, we uncover the hidden engineering behind lift axles—why heavy trucks intentionally raise and lower their wheels while driving, how this protects roads from damage, saves fuel, reduces tire wear, and prevents massive stress during sharp turns.

You’ll discover:

Why roads are more fragile than they look

How weight distribution matters more than weight itself

The real reason trucks don’t keep all wheels on the ground

And how a simple analogy—high heels vs sneakers—explains it all

This isn’t a malfunction.
It’s a real-time engineering decision.
