Wondering how to get rid of noisy tires? Looking for more comfort? In this article you discover new advancement in tire technology.
Pirelli Tires Most Advanced in the World
Pirelli has developed new tires for Audi Group cars that are designed to reduce noise for the occupants of the car. This is the latest milestone in the historic technical partnership between the Italian tire firm and the German car manufacturer. As a matter of fact, for the first time the Milan-based firm is supplying the “Pirelli Noise Cancelling System” as original equipment: a system that reduces the noise that each tire makes as it runs along the road.
This noise, caused by the vibration produced by air that is compressed when the tire is squashed against the road, is transmitted from the tire to the wheel hub before eventually reaching the inside of the cabin, via the steering and suspension.
Pirelli’s innovative system makes use of a polyurethane sponge on the inside of the tire that is designed to absorb these vibrations and so reduce the amount of noise passed through to the cabin.
The “Pirelli Noise Cancelling System” reduces noise by between two to three decibels, or on average by half, with a consequent improvement in driving comfort.
Pirelli’s development tests have confirmed that the use of this noise-reducing sponge does not have any other effects on the characteristics of the tire.With the introduction of this technology for original equipment, Pirelli is answering a growing demand in the automotive world for reduced noise levels both on the inside and outside of the car, and addressing the latest European regulations to reduce noise pollution, as manufacturers are required to respond to. At the moment the “Pirelli Noise Cancelling System” is available as original equipment on the Audi RS6 and RS7, running on 275/35ZR20 and 275/30ZR21 P ZEROTM sized tires respectively.
The tires using this system have the letters ‘PNCS’ written on the sidewalls to denote its use.
