The tyres are coated internally with a layer of foam that has a strong damping effect on the sound waves generated by the rolling tyre. Tyre noise, it says, is "substantially reduced no matter the surface on which the vehicle is being driven".AUDI THE FIRSTContinental says: "All ContiSilent tyre components and the tread pattern are adopted from standard production tyres, with performance characteristics such as braking, handling or wet performance unaltered. The tyres are compatible with standard rims and fitting."Audi is believed to be have been first to fit these tyres (to its RS 6 Avant and RS 7 Sportback) and says the RS 6 Avant will be equipped with 285/30 ZR tyres on 21" rims, the RS 7 Sportback will have 275/30 ZR1.The flagship Audi A8 will also be equipped with ContiSilent tyres from the ContiSportContact 5 range.
