My friend recently traded his stunning 2007 CL600 for an equally stunning 2015 S6.3 coupe .
There used to be a certain amount of tyre noise with the older car and the tyres on the newer one are maybe halfway to needing replacement. The newer car has more tyre noise than he was expecting, it rides on 20" non runflats.
I have the S class saloon running on 19" regular tyres so mine runs very quietly with virtually no tyre noise.
What brand of tyres are others running and what are your thoughts on tyre noise with the coupes please.
Thanks in advance.

I went from a 2007 CL500 with 18 inch Michelin Pilot Sport 3 to a 2016 S550 coupe with 20 inch Goodyear F1 RFs. I found the tire noise to be only a bit more noticeable in the S550. I now have 20 inch Michelin Pilot Sport 4 ZP (run flats) and the tire noise is reduced compared to the Goodyears.

you dont get much tire noise on new tires. when they wear they make noise. The wider, the more noise. But I cant hear any noise from my S550 either way

Thank you both for your comments , I will pass them on to my friend tomorrow, I think that is correct bout brand new tyres being less noisy as well, thanks.

I'm a huge Michelin fan and have them on all my cars now. Having had the same issue on a few other cars, CL500 for one. Tire noise is a product of having a car that's so quiet, you end up hearing tire noise Perhaps the noise expectation or lack of, goes up as our taste in cars rises. One tire that worked pretty well and my driving style fit with it, is the Hankook Ventus 12. Affordable, decent performance and quiet....but seems to wear quickly. The other tire that seemed to be a tad quieter is Bridgestone brand, asymmetrical treads and various Potenza summer tires??? However, I chased the noise issue for a long time and unless you buy tires every 4,000 miles, as they wear most all will end up singing to you.

Lastly, I've moved from 20s to 19s on my BMW and would like to on my S63, non-runflats, and it seems adding sidewall height reduces noise. Possibly the stiffer, shorter sidewalls of 20s inherently amplify noise. Tell your friend congrats on trading up and put some good music on to drown out the tires...

SpiderAce, Thanks very much for your thoughts, my friend is very pleased with the S63 coupe, even though it has only been a few weeks, his cL600 was a lovely car as well,
such a lot of car for the money,

Said it best When the car is so quiet you can hear even the tiniest breathing from other passengers hah!

A balance between performance, affordability, tread wear and noise really depends on the person, but after a bit of wear there's bound to be some noises, and that's with the highest quality tires too unfortunately...

Lose the 20" wheels if you don't want tire noise. Lose the 20" wheels and you'll stop having busted wheels due to pot holes on the interstate hwy.

YUP!

As cool and nice as the 20s look, I still can't find any real reason to run them on the street. If you track your car or value looks over function, then that may make sense. For me you can retain 90% of styling and performance with 19" and have a much more rewarding daily driving experience. The tradeoff is too one sided.

Since owning an SL400, I've always found for Goodyear Asymmetric series to be the quietest and I wouldn't have any other make now

I too am a Michelin fa. I am running Michelin pilot sports on all my M-B's. I have 19's on my S560 coupe and find them very quiet and smooth.
However, I concur with others in that I have 20's on my S550 Cabriolet and they are noisier.
Also, type of pavement will make a big difference in road noise generated.
