Hidden Foam Inside Tires That Reduce Road Noise #engineering #car

Quiet tires were first developed in Japan, based on a surprisingly simple concept. By applying a layer of sound-absorbing foam to the inner surface of a tire, cavity resonance is reduced, significantly lowering road noise. What makes this innovation even more interesting is that older tires can be retrofitted with the same foam layer, delivering results nearly identical to newly manufactured noise-insulated tires.
Despite its effectiveness, this technology has seen limited adoption in Europe, particularly in Germany. High labor costs and concerns over manufacturer warranties have slowed its acceptance. In contrast, countries like China have widely embraced this modification, with workshops offering fast and affordable installation. This video explores how the technology works, why adoption differs across regions, and what it means for the future of quieter driving.
