That's why the electric car tire is so quiet!
May 21, 2024
Traveling in a gasoline-powered car and an electric car is a completely different experience – just considering the sound effects. The electric car glides quietly on the roads, focusing solely on the road thanks to the use of tires. But how does this type of tire make it possible? We investigated!
Noise in gasoline vehicles and electric cars
If you get into a traditional car, you will always experience some background noise that comes from the internal combustion engine. The cause of this phenomenon lies in the laws of physics: when thermal energy transforms into mechanical energy, the engine cylinders start to pulsate. This pulsation can be perceived by our ears through the exhaust.
You don't need to expect this kind of noise in an electric vehicle. You rightfully expect your electric car to operate almost silently since it works with a battery instead of a noisy internal combustion engine. Electromagnetism, after all, is silent.
However, there is no sound to mask the rolling noise. The strength of the so-called tire white noise also depends on the condition of the road we are traveling on and how fast we are driving. Additionally, the tread pattern of the tires or the material of the rubber also matters from this perspective. The noise levels pleasant for us range up to 100 dB (decibels), but values above 120 dB can be painful to listen to.
The secret lies in the structure of electric car tires
For all these reasons, one of the biggest challenges for tire manufacturers is minimizing noise levels. However, the latest electric car tires easily meet this challenge with their design:
Acoustic lining: in this case, polyurethane foam is glued to the inner surface of the tire. This lining significantly dampens vehicle noise. Some brands' products even promise a 20% noise reduction (and some even close to 10 dB noise reduction).
Tread pattern, sound-absorbing rubber mixture: the special design of electric car tires also ensures that our journey is as smooth as possible.
Wear resistance: thanks to this, they will withstand the load better and preserve their original condition for a long time.
