We Didn't Know How Tyre Sounds are Made Until Now

By Andrew Liszewski on at

With supercomputers capable of beating our best chess and Jeopardy players, you'd think that being able to simulate the sounds a tyre makes while rolling on a road was easy—but it's not. In fact, Yokohama had to team up with the Japanese equivalent of NASA to finally recreate how air and sound behave around the company's tyres.

Working with the Japan Aerospace Exploration Agency's Institute of Space and Astronautical Science, Yokohama's researchers used a detailed 3D model of a tyre to finally simulate how the sounds it produces are created. And it turns out those sounds are not only produced by all the air turbulence around a rolling tyre, but also by the constant compression of air in front of the tyre where it meets the road, and as it circulates around it.

So what's the benefit of roping in a bunch of rocket scientists to study how a tyre makes noise? Not only will these simulations help Yokohama produce quieter tyres, that in turn make for a more peaceful ride inside a vehicle, it will also allow the company to improve the aerodynamics of its products which in turn means better fuel mileage or a longer range with electric cars.
