🚗 The Reason Why Tires Deform During High-Speed Driving

In the video, you can see scenes where rapidly rotating tires visibly stretch and expand.

The cause of this phenomenon is none other than centrifugal force. As speed increases, the rubber is pulled outward, increasing the diameter and causing slight deformation in shape.

When frictional heat and rising internal air pressure are added to this, the tire swells even more. This is because as the temperature rises, the air expands, and the rubber walls become flexible and temporarily weaker.

However, although a tire looks like simple rubber, steel belts and nylon fiber structures support the interior like a grid. Thanks to this, it disperses centrifugal force and pressure, maintaining its circular shape as much as possible even at high speeds.

Considering all these physical forces, engineers set a ‘speed rating’ for each tire. It is the result of precise engineering design capable of withstanding pressure, heat, load, and even deformation.

🏁 A tire is not just simple rubber. It is the culmination of perfect engineering that maintains its form even at super-high speeds.
