How Has Technology Made Tyres Quieter?

Using foam, that’s how.

Over the years, car engines have become quieter especially with the developments in popular electric and hybrid technologies. However, this means that the interior and exterior noise created by tyres is more noticeable which can make your in-car experience far less enjoyable.

At Goodyear, we pride ourselves in craftsmanship and innovation so we strive to make your journey as pleasurable as possible. Our tyres are specifically #MadeToFeelGood.

Recently, we have been investigating the ways that we can adapt our tyre designs in an innovative way to make them quieter without affecting any of the other key properties or performance of the tyre such as rolling resistance, handling, braking and tread wear.

The most prominent interior noise we hear is tyre cavity resonance – but what is it?

The noise is caused by air that fills the space between the tyre wall and the wheel itself. This air vibrates when the tyre is moving in contact with the road and can be heard within the car. We’ve devised a simple yet effective solution to the noise problem; SoundComfort Technology to the rescue.

An open-cell polyurethane foam element is attached to the inner surface of the tyre. The technology dampens the tyre cavity resonance sound peak that is generated when the tyre rolls over a surface, by up to 11dBA and enables a vehicle interior noise reduction of up to 4dB.

SoundComfort Technology is cost effective, stable over the full life of the tyre and is light enough to avoid any negative impact on mileage, rolling resistance or speed capability. It is available for summer, winter, All Season and RunOnFlat tyres.

We expect to see this technology used more and more in the future by tyre brands, as it is affordable yet highly effective at reducing in-car tyre noise.

But what does the future hold for reducing tyre noise – where will the technological developments take us next?
