DOES FOAM IN A TIRE TRULY QUIET DOWN ROAD NOISE IN AN EV?

EV Channels Review

This video from EVChannels explores the effectiveness of Goodyear's SoundComfort technology in reducing road noise in electric vehicles, specifically testing it on a 2018 Tesla Model S 90D. The core of the review involves a back-to-back comparison of the same tire model, one with and one without the foam insert, conducted at Goodyear's San Angelo proving grounds. The reviewer highlights that EVs, lacking engine noise, are more susceptible to road and tire-generated noise. Goodyear's SoundComfort technology, a polyurethane foam applied to the tire's inner liner, aims to reduce cavity resonance and booming noise. While the reviewer acknowledges the subjective nature of NVH testing and the extensive training required by Goodyear's engineers, they report a noticeable and significant improvement in cabin quietness with the foam-equipped tires. The difference was so pronounced that it felt like driving on a different surface, with the foam effectively reducing intrusive ringing and booming sounds, making the overall experience less annoying. The video also touches upon the engineering compromises involved in EV tires, balancing range, grip, and noise reduction.
