When you eliminate the internal combustion engine from a car, the lack of engine noise highlights other sounds that would have otherwise been drowned out. This is actually a big issue for engineers working on electric vehicles, and one of the biggest sources of peace disturbance in the cabin are the tires.
Tire roar is really noticeable in EVs, in some cheaper vehicles it’s almost a problem, but tire manufacturers are working on ways to improve their products specifically for electric vehicles. Our own Kyle Conner visited one of GoodYear’s tire testing facilities, in the middle of nowhere, close to San Angelo, Texas, to learn more about the process of making EV-specific tires and especially the foam that they now put in tires to help quiet them down.
