Michelin Pilot Sport 4S Acoustic/Noise Cancelling
Anyone running these ? I have a set on the way. It has the exact same handling, grip, etc of the 'regular' PS4S, but there's a bit of foam imbedded making it very quiet.
I spent about 20 minutes on the phone with Michelin tire yesterday confirming they can be used on M550's. They're about $35 more than the regular PS4S. The tire was originally produced for the Tesla, but they make several sizes of it now. Last edited by HerkHealer; 10-23-2021 at 03:42 PM.. |

Will do ! I cant imagine the Super Sports are louder than these crappy Goodyear Eagle F1 runflats I have on right now. Did quite a bit of homework on these. The PS4S replaced the Super Sports in 2017, with a tad bit better noise, grip and longevity upgrades. The "acoustic" version is the same PS4S tire, but adds a thin strip of foam to keep it quiet. The Michelin tech I spoke to said they are virtually silent.

They're HERE !
They came in early !
I believe these are only available in the Non-Runflats only for those wanting to know. A few pictures. On the tag, you can see "acoustic" with a pair of headphones under the ZR20. The foam is glued down inside. I have too many wheels and tires.. The ones in bag are my winter wheel/tire set. Last edited by HerkHealer; 10-23-2021 at 03:46 PM.. |

Non run flats are definitely always going to be quieter than run flats. Can't wait to "hear" what you think. Are they star marked? Where did you get them? Tire rack?

Hi Joe,
When I spoke with the Michelin Tire rep the other day, he looked up the OEM tires for our M550's. They are the Michelin PS4S and the (awful) Goodyear F1 Runflats. So they are definitely approved. I bought them on Ebay from this seller. https://www.ebay.com/usr/hockey1242gk2 $506 shipped for 2 brand new tires. Considering 1 of them is $450, it was an easy decision. Still debating whether to mount my new PS4S now, or wait until Spring. Its getting close to putting the winter set on. Mark |

As soon as I got them, I went over them with my 2x reader glasses and my spotlight. Perfect condition. No cracks, dryness, etc. They have PLENTY of these in stock she said. I guess they buy auctions of overstock or businesses going down. |

This ebay seller likely purchased them at auction from a dealer/distributor moving old stock. Michelin, and most other OEM's, do not want dealers holding tires longer than 18-24 months from manufacture date. Hopefully the foam addon provides some sound deadening you're hoping for. I have the Michelin PS3ZP (run flats) on my G30 and I find them to be quiet until they're close to the end of life. Even then, the noise isn't noticeable, except when decelerating to a stop.

Just put them on and hopefully they're good. Make sure you find a shop with a lever less tire mounting machine. Common tire shops will mangle your rims trying to r&r these low profile tires.

Totally agree with you and would jump on this deal in a heartbeat but my dealer unfortunately won't install any tires they didn't sell, apparently for liability issues.

Tirerack often recommends a mobile company called Tread Connection. Their trucks are outfit with high end Corghi (Italian made) contact less or lever less mounting machines and Corghi's diagnostic series wheel balancers. I've had experience using their services and was happy. The tech was careful and did a great job. The dealer also has excellent equipment as required by BMW.

Now all this said, I have no issue just paying the dealer 10% more and keeping them in my good graces. Hopefully they will get me these acoustic ones when I need new rubber.

For those in the MA/NH area, Tulley BMW of Nashua is going to mount the tires for me. $185 for everything. I'm also going to get an alignment done that day also. Just to make sure all is perfecto. Last edited by HerkHealer; 10-27-2021 at 02:28 PM.. |

For a daily driver, those dates would not bother me. Unfortunately for my M550ix I'm only putting a couple thousand miles per year on it (hopefully more next year), and I would end up replacing due to age, rather than miles. Most tires are recommended to replace by 6 to 7 years (varies by manufacturer). I always inquire on tire age when purchasing.
