Installed Michelin Pilot Sport All Season 4's
Michelin Pilot Sport AS 4 20”
City driving 35 mph
Comfort: 9.5; dull thud over minor road imperfections
Quiet: 9.5
Highway 75 mph
Comfort: 9; very smooth
Quiet: 9; 1 db quieter than Pirelli RF’s (phone db app), might be mental optimism but I could tell a difference
For comparison…
Pirelli P Zero Run Flats 20” (previous tires)
City driving 35 mph (same route)
Comfort: 7, harsh over minor road imperfections but generally comfortable
Quiet: 9; never an issue with RF’s here
Highway 75 mph (same route)
Comfort: 8, obviously feel more "road" versus non-RF’s but still smooth
Quiet: 8; 1 db louder than AS4's
IMO the S560 with RF’s is more comfortable and quieter than my previous car, 2016 LS460 F-Sport with 19” Bridgestone Quiettracks (clearly MB car design & engineering)
Bridgestone Quiettrack 19” (LS460)
City driving 35 mph (same route, but about 5 mins after tires warmed up due to resting flat spots)
Comfort: 8.5
Quiet: 8.5
Highway 75 mph (same route)
Comfort: 8
Quiet: 7.5; 4 db higher than AS4’s; used a different phone app at that time (not a fair comparison); S560 with RF’s is quieter
Other notes:
Tire lip extends noticeably further out from the wheel versus the RF's (and thicker), which I like. Perhaps this will give a little more wheel protection against curb rash.
I'm also in a 4 season location so traction and tire integrity will be greatly improved during cold winter months versus summer RF's
Interesting that you found your S on RFTs rides better than a Lexus LS on Quiettracks. Many have praised the QTs on their S, so it seems to say the S is inherently a much better riding car than the Lexus..

Using a phone dB meter app I get about the same reading in the S560 I got in the LS, but on a calm day the S560 feels quieter. Windy day, less so.

62 years is a long time. I respect that. It may be that I am a bad driver. However you live in Florida, There are no pot holes in Florida. In the north east the roads not as good. For that reason I run run flats.
