Ever striving for quieter, more comfortable tyres, tyre manufacturers are looking at increasingly novel ways of achieving sound reduction. Goodyear is one of a number of manufacturers attempting to solve the problem with foam, or as the press release puts it, an “open-cell polyurethane foam element attached to the inner surface of the tyre.”
Apparently this is good enough for a 4db noise reduction in the cabin, and is light enough to avoid any impact on fuel consumption. Already being fitted to the new Audi A8, RS6 and RS7, it will be interesting to see if this is the next step in lower label scores and increased driving comfort.

New Tyre Technology
Goodyear reduces interior car noise levels with new SoundComfort technology Four decibel noise reduction is something to talk about Birmingham 23rd May 2014 – Goodyear announces today that it is launching a new technology that addresses the noise caused by the tyre cavity resonance.
Goodyear’s new “SoundComfort” technology features an open-cell polyurethane foam element attached to the inner surface of the tyre. The technology dampens the Tyre Cavity Resonance (TCR) sound peak, generated when the tyre rolls over a surface, by up to 11dBA and enables an vehicle interior noise reduction of up to 4dB, making the vehicle cabin significantly quieter across a large range of vehicle speeds.
The new technology is designed to make the overall driving experience more pleasant.
Goodyear’s 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.
“As car manufacturers continue to perfect their vehicles, noise reduction has become an integral part of their drive to improve overall driver comfort”, says Xavier Fraipont, Director Technology Consumer Tyres EMEA. “Today Goodyear is joining this effort with SoundComfort Technology and is thereby making a significant contribution to overall noise reduction in the car.”
