I have the 21” Michelin PS AS4 tires and Mountainpass Adjustable Comfort Coilovers, rpmtesla noise deduction kit with extra sealing added to hatch (will address a lot of boom).
The most significant fix for all the road noise has been applying butyl and foam sound deadener inside the front wheel well liners. There’s so much road and tire noise that is generated here and passes into the door area which is separated by thin sheetmetal from fender, and also transmitted into the cabin through the firewall and other means, and the front fender liner itself is not properly flocked to absorb/dampen sound (rears are much better). Any noise that gets into the cabin is magnified, in a boomy manner with some echo; try being in front seats with door open and talking to someone who is standing outside.
It took me about 3 hours for each front fender to dismount wheel, remove the fender, apply material and reassemble, but well worth it. I’ve been driving on these for a week and have been very, very happy with the car. It makes a profound improvement in comfort. Difference is like sleeping under a thick comforter.

While there is sound improvement to be made in quieter tires, don’t assume it will solve all of it in the Model Y. If you stand by a busy road with any texture and watch cars go by, there’s a high level of tire noise generated regardless of tire. If someone zips by in silence, flag that car down and ask for what tire they use. Personally I would always go for the safest tire that gives great confidence in all conditions I drive in; mildly quieter than original tire is a bonus.
