I’ve had Pilot Sport 4Ss installed on my M40i for a few weeks and am happy to report that they feel very good and are, I think, a significant improvement over the Alenzas (on 21” wheels) and Yokohamas (on 19” wheels).

By far the most noticeable difference is how responsive the tires feel — even on the M40i, they impart that “telepathic” feel that I’ve always associated with Michelin Pilot Super Sports. I think that arises from a combination of precise steering and instantaneous reaction from the tires. This is noticeable even when I’m driving below 8/10ths, and it feels great.

I suspect ultimate grip is probably materially improved, but honestly did not have the opportunity to push the Alenzas or Yokohamas hard enough to say for sure. I can say that AWD + grip means that this thing accelerates through corners in a way that my m235i just can’t, and the difference there is large.

All that said, even with pilot sport 4Ss, I don’t think this quite feels as good in the corners as the GLC43. The M40i is a much better all around package, in my view, and represents a much better mixture of ride quality + handling, but if I was only concerned about fun in corners, I still think the GLC43 wins.

Nice review!

Did you find the 4s in 21" size?
I don't see them on tire rack.

No, they are 20” size. Thought that there is a non-oem size 4s setup for 21”s, but haven’t investigated.

I am on my second set of Pilot Sports 4Ss on my Z4M roadster. I like the grip, quiet operation, and smooth ride. With 500+ HP, they don’t last long - they actually howl under hard acceleration - but for 18”, they were priced competitively.

I'm confused by your original post b/c you compared your review to 21" and 19" wheels. So you have a 2nd or 3rd set wheels in 20" or you are just comparing to when you test drove other M40is?

And I've had no luck finding the 4s in 21"

I had them on my E92 M3 Competition package (19"). Great grip, quiet and the ride was good.

I hope that when the Bridgerocks are done there will be a Michelin 4S in 21"

Long story, but 3 test drives on 21” and then bought with 19". Now have 19" wheels with winter tires (switched to Pirelli Scorpions from Yokohamas) and a second 20" set with 4Ss.

That's what I'm hoping too as well.
