Pirelli has designed new OE tires for the Audi Group that will reduce noise inside a car.

This is the first time the company will offer its “Pirelli Noise Cancelling System” as OE.

The system is designed to reduce the noise that each tire makes as it runs along the road. The system utilizes a polyurethane sponge on the inside of the tire that is designed to absorb vibrations, cutting the amount of noise that reaches a car’s cabin.

The “Pirelli Noise Cancelling System” reduces noise by between two to three decibels, or on average by half, according to the company.

Through testing, the company has confirmed that the use of this technology does not have other effects on the characteristics of the tire.

Currently, “Pirelli Noise Cancelling System” is available as OE on the Audi RS6 and RS7, running on size 285/30ZR21 and 275/30ZR21 tires. Tires with the new system have the letters “PNCS” written on the sidewalls.
