Any thoughts on PS 5 S?
I just ordered a set to replace my PS 4S's. The fronts are getting close to the wear bars. The rear still have meat but I'm a little leery of having different compounds on the two axles. They're supposed to have more dry grip and 300 wear rating. Sounds too good to be true. Anybody have them?

The PS S 5 (notice they changed the nomenclature. It's not 5S, it's S 5) is only available as OE tire at the moment, not aftermarket. So since AMG is using them on the newer vehicles, I guess they are becoming available in the needed sizes for older vehicles. But this is to say that not many people have experienced them yet. My understanding is that the PS S 5 incorporates a lot of the learnings that Michelin made from developing the BMW Star marked PS4S for the M3/4. As opposed to the aftermarket PS4S, the BMW Star variant uses 4 compounds and is based on the Cup 2. I've got the BMW Star variant PS4S on my C63S Coupe and it's a phenomenal tire. I wish this is what the PS4S were from the outset. If the aftermarket PS4S dialed it up to a 110% from the stock Pilot Super Sport, then the BMW Star dialed it up to a 130%. Steering response, handling and grip is all up a couple of notches, so I expect the PS S 5 to be fairly similar. The only caveat is that the added dry performance comes at the cost of reduced wet performance, but here in NorCal with only about 60 wet days on average, wet performance is not something that matters much for me. It'll be interesting how the wet performance of the S 5 compares. Wet vs dry performance is always a balancing game and BMW deliberately emphasized dry performance, so it's possible that the S 5 has reduced dry performance compared to the BMW 4S, but increased wet performance, but then AMG will have done its own thing with the MO1 variant.
I posted the Tyres Review video of the BMW Star 4S a few times, so if you haven't seen it already, I can post it again. That should give you an idea of where the PS S 5 will be relative to the PS4S.

Great summary : ) I wonder when will they finally sell it to the aftermarket, because it has been at least a year now? I think?

It is unusual for Michelin to release a new tire through OE channels only, and not make it available in broader sizes to the aftermarket. I've long suspected that Michelin essentially took the BMW 4S with perhaps a few minor tweaks and made it available to other OEMs in the form of the S 5 and they are largely the same tires. Michelin spent 2 years developing the BMW 4S and if you look at it, it really is a different tire. It's not really a 4S anymore. They changed the internal construction and the compound over the aftermarket 4S, going from 2 compounds to 4 compounds like the Cup 2.

They are all OE tires. Mercedes, Porsche and Aston Martin. Except for two sizes. 245/40R21 and 275/35R21. They are both listed as SL tires with 96 and 99 load rating and not Z-rated. So, not sure what those are all about. Looks like an error.

Exactly, these are all sizes used on current models. They will happen to overlap with some older models that use the same sizes, just like the BMW Star PS4S happens to match the stock 19/20" sizes and load rating of the C63S coupe stock tires. Keep in mind, the size is only one aspect. You need to have the correct load rating, too.

A bit of a follow up. Finally had some time to hit up the canyons with the new BMW 4S and if I wasn't already impressed before, I'm definitely now. These things are next level, so hopefully the PS S 5 is at the same level. Seems to have endless grip and even on bumpy roads they just stick. Very progressive at the limits and easy to control a drift. The regular aftermarket PS4S wasn't bad, but these things are almost telepathic with their feedback. I had to learn to trust them and they'd let me know with plenty of warning when they started to lose grip. Ambient temps were around 100F and I had the fronts almost at 200F and the rears around 150F. While the aftermarket PS4S occasionally struggled for grip at similar temps, these things were glued to the road. Seems they maintain the contact patch much better together with the AMG Ride Control suspension. Hope somebody is gonna do a comparison between the BMW 4S and PS S 5. Very curious now how they compare, and if they are indeed essentially the same tires.

I put these on last December and they were performing equally well compared to the normal PS4S. Can't really tell any difference w/o measuring it. The mild winters here in the Bay Area are not really a challenge for these. Sure, they don't have nearly the same grip they have in the summer and with RWD I have to short shift and manage the traction, but that's only if I gun it. For normal driving they don't budge even on nights when temps drop slightly below 40F. Once driving, they warm up anyway.

I'm waiting to put more miles on them before I post a review, but so far I'm very impressed with these tires on the first couple of hundred on the E63. Handling is crisper but even more stable feeling than the 4S. Road noise is very noticeably reduced.
