Rolling Noise: How Continental Is Making Tyres Even Quieter
- Special tread design noticeably reduces rolling noise of Continental tyres
- ContiSilent technology reduces interior noise for a much quieter, more comfortable in car experience

Hanover, Germany, March 20, 2026.
Continental is developing tyres with exceptionally low rolling noise, helping reduce overall traffic noise and improve comfort inside the vehicle. This is made possible by innovative technologies and tread designs. Alongside air pollution, noise is one of the biggest burdens for people and the environment – especially in urban areas. The World Health Organization (WHO) ranks traffic noise as Europe’s second-largest environmental health risk. In megacities across Asia and Latin America, noise is a daily challenge. Reducing overall noise emissions is therefore crucial – and tyre noise is no exception.
Rolling noise is influenced by several factors, including tyre type and tread design, road surface and individual driving behavior.
Tyre noise typically becomes audible to the human ear at moderate driving speeds. At lower speeds, engine noise dominates. With the shift toward electric mobility – and the much quieter motors of electric cars and buses compared with combustion engines – the importance of low noise tyres has grown significantly.
“Noise, especially traffic noise from cars, buses and delivery vehicles, is a major burden for people and the environment. With tyre technologies like ContiSilent and innovative tread designs, we are actively reducing rolling noise without compromising safety,” says Achillefs Tsotras, head of Continental’s Tire-Vehicle Interaction department. “This makes every ride noticeably quieter, benefiting drivers, pedestrians, residents and the environment alike.”
Continental places a strong focus on developing quiet tyres without sacrificing safety or performance. Rolling noise occurs when tyres come into contact with the road. The resulting sound is only audible within certain speed ranges – typically from about 30 to 50 km/h up to 80 to 100 km/h. The exact noise level depends on factors like road surface, drivetrain, tyre type and driving style. Generally, at lower speeds, engine noise masks tyre noise, while at higher speeds, wind noise tends to dominate.
Silent Pattern tread design reduces rolling noise
To specifically target tyre noise audible to humans, Continental has developed the Silent Pattern tread design. This tread is optimised for sounds that occur at around 50 km/h, the speed at which rolling noise is most noticeable. To reduce this noise, the spacing and angles of the tread blocks have been deliberately varied. On conventional tyres, evenly spaced tread blocks hit the road at regular intervals, producing an audible humming sound. By contrast, the irregular arrangement of the Silent Pattern blocks breaks up this regular rhythm, reducing the humming noise. In addition, the pattern is specifically tuned to cancel out noise emitted by the different tread elements – similar in effect to noise-cancelling headphones. The result is reduced road traffic noise in urban areas, making busy streets noticeably quieter for pedestrians and residents.
ContiSilent: special foam inside the tyre absorbs noise
To reduce noise inside the vehicle and enhance comfort, Continental offers its ContiSilent technology. This can reduce rolling noise in the vehicle cabin, caused by air vibrations inside the tyre, by up to nine decibels. Since the human ear perceives a 10-decibel reduction as halving the volume – regardless of the surrounding noise levels – ContiSilent has a major impact on driving comfort. The ContiSilent technology uses a special, ultra-light polyurethane foam applied to the inside of the tyre during production. This foam absorbs part of the tyre’s vibrations, preventing them from reaching the vehicle interior. Driving performance, fuel efficiency, load capacity and top speed remain unaffected. Designed for summer tyres, ContiSilent is available on various products, including the ultra-high-performance SportContact 7. Continental offers a wide range of tyres engineered for low rolling noise, including the EcoContact 6 Q summer tyre for passenger cars. When shopping for tyres, customers can easily identify low noise options by checking labels – such as the EU tyre label – which clearly indicate noise levels in decibels.
The EU tyre label shows how noisy a tyre is. Noise levels are typically classified into categories and measured in decibels (dB).
