UPDATE:

I went to America's Tire and the front measured 7/32 and rear 3/32. Something was definitely up. The worker was surprised it was that low. I got pro-rated warranty on Michelin Pilot A/S 3+ (plus) since I wanted to have similar level tire all around. Hopefully this lasts longer than previous gen.

Do you have a 16 year old son that drives the car?

[fcman]

I have ~22k and ~40 hard autocross runs on my rears and they are just now ready for replacement, not quite bald yet though. Fronts are fine, probably have another 5-10k on them.

225/40 MPSS fronts - after 21,000 miles and no rotation, noticed some cords showing on the inner shoulders when I changed the oil this weekend. Car was in the shop a month ago, and they didn't mention it, so must be a pretty new development. (N55 E88 - Dinan camber plates; I think I'm set about 1.6-1.7 deg negative. Perhaps I'll have them back it off to around -1.3. Though I don't think 21k mi is too bad on a set of Super Sports on this car.)
Love 'em so much, I'm replacing tires with the same thing again.

I didn't see any such nonsense on the rears when I did the brakes 3 weeks ago. They are getting near the wear bars, but not quite there. Winter is mostly over, so I'm going to see if I can stretch them through, or at least into, the summer.

I try to keep 'em at 36psi front, and 39 rear.

[tjswarbrick]

Can't stretch them to the end of summer...
Lost the right rear over the weekend. (Inner edge worn through.)
245/35-18.
Darn near 26,500 miles. So I can't complain.
Did I really drive 5000 miles in the last 3 months?
Just did the math. Yes. Yes I did.
Left rear is at the wear bars, but no belt exposed yet.
Getting 255's this week.

[Cavpilot2k]

I got somewhere between 15-20k out of my last set.

Quick update: Skip's and America's Tire just informed me the 255/35-18 MPSS has been discontinued, intended to be replaced with the S4S.
Luckily there are still a few kicking around in stores, so I can get a pair this weekend.
Goes quick - in February they couldn't find S4S for the fronts...

From what I've read the Michelin Pilot Sport 4 is a direct upgrade (ie. better in every way) for the MPSS.

What's more, (in Australia at least) the MPS4 is cheaper than the MPSS.

MPS4S is coming, and you'd have to assume it's sportier again - but not yet sure it's going to be available in the sizes we need.

[tjswarbrick]

Better in many ways, and not worse in any, from what I've seen.
I would've been happy with S4S's, and probably gone that way if I did it all at once now. But prefer not to mix rear S4S with front PSS.

[Eyeman]

Yep, I had to go with S4s up front. So far they seem even better than the PSS. For sure the sidewalls are "prettier" to me, if you are into that.

This thread caused me a mild panic, as my front 225-section Michelin PSS are still at nearly 9/10 32nds, but my rears are coming due for replacement. The last thing I'd want to do is end up having to replace the entire set with the PS4S, as my fronts are essentially new.

I got in touch with my tire guy this morning, who informed me that the Michelin PSS is still available in the 255/35ZR18 size I need for the rear. I'm simply going to buy a pair and store them until my rears are finished.

I guess there's one benefit to not having much power . Interesting that you (135's in general) are going through rear tires about twice as fast as fronts while 128's are pretty even in treadwear. I wonder if it's all because of the power, or other factors in the suspension...

On my 135, fronts were done at 21k miles, while rears still and had about 2k (serviceable) miles left.
All 4 wear more on the inner edge, but I do have a bit more negative camber up front.
Perhaps rear treadwear depends on how the car is driven...

Power is definitely a large factor in how long tires last, but above all, it's my driving. I have a very heavy right foot. I've always kept my various BMWs properly aligned, but that hasn't stopped me from going through rear tires faster than most. Even when I was driving my E46 330i or E36 M3, I considered myself lucky to get more than 12k out of a set of rears.

Just for reference, my current rear PSS have have just under 7k on them and will be ready for replacement soon.

[Cavpilot2k]

I'm pretty sure the replacement for the MPSS are the PS4S, NOT the PS4.
My understanding is as follows: MPS4S > MPSS > MPS4.

I went from MPSS to 4S and WOW! Every bit as good if not better than PSS on dry pavement and a dramatic improvement on wet.

I LOVE the MPS4S!!!

MPS4S > ( MPSS ~= MPS4) > MPS3

Edit: the problem is you can't buy MPS4S in all the right sizes (yet) - but the MPS4 is everywhere.

Michelin say:
While Pilot Sport 4 replaces the Pilot Sport 3, it’s an improvement on the Pilot Super Sport, not a “new” Pilot Sport 3, in design and technology. In comparative testing in 18" sizes, Pilot Sport 4 outperforms the Pilot Super Sport in 99% of everyday situations, with the added benefit of 10-15% improved wear. The other 1% is on a dry track where the Pilot Super Sport would outperform the Pilot Sport 4 by a couple of tenths of a second around a long track. For more track focused track drivers we will expand the range of Pilot Sport Cup 2 over the next few years.

It's funny the article would say that.
I guess it depends what one prioritizes.
Not to be argumentative, as it's a moot point since the 4S is better than both, but...
If you look at the numerical rating system for the two tires on the Michelin website, they rate the MPSS higher on handling, and wear life, where they rate the MPS4 higher on comfort and fuel efficiency. They come in equal on braking.
To me, since they are supposed to be ultra performance tires, that puts the PSS higher than the PS4 (because we don't buy ultra-performance tires for ride comfort or fuel efficiency).

I don't know about availability of sizes, but I was able to get the 4S sizes I asked for delivered for installation the day after I requested them at my local tire shop. (235/40r18 and 255/35r18).
YMMV.

I'm excited that they now come in 225/45-17 (the only 17-inch size available) for the E36 M3, which means that I could get a pair for my car. If only they weren't so dang expensive...

I only saw about $20-30 a tire more than the MPSS. I know it all adds up, but I just figure a new set of rubber is gonna run me $1000 give or take and suck it up.

I'll stick with my idea of Falken RT615k+ for $360, and then take the money saved from Michelins and get a bucket seat, or put it towards a diff, etc.

Really, though, it's a matter of personal taste. I like to save money on things that are within 80-90% of the capability of the more expensive product, but only around 40-50% of the price, and then use those savings for another thing...

Fair point.
And with that approach you will be able to afford more mods than I will.

True, but you'll have all the peeerrrfect ones
