So, after 26k on the factory Pirelli P Zero run flats, it's time to get some new boots. Pretty pleased with how these have done to be honest mileage wise, but like the idea of getting away from the skiddy cold weather behaviour and crashing over bumps from the runflats.

I have the MSport plus upgraded 19" wheels on my 335dx and it seems from reading a fair few threads on here that I would be a fool to overlook the Michelin Pilot Super Sports.

So, what's the best prices people have seen recently?

Also, going to need a slime/pump type kit, any suggestions on that are welcome too

Many thanks

Black circles or tyreleader is your hunting ground for best prices. There are some others.

I bought the Continental tyres mobility kit, there is a Ford dealer down Bristol way that sells them for good prices. Apparently they are used in some Fords. Cheaper than the genuine BMW kit and it looks like BMW sell the older exposed bottle version. The new one is very neat.

Others use slime and a foot pump, or compressor. I personally wouldn't use a foot pump. If the hole is big enough you'd be knackered by the time you put enough air in

[JNW1]

I have the same Continental kit as NISFAN but can't say how good or bad it is as I've never needed to use it (and hope I never will!).

On the tyre choice, my car's on Goodyear AS2's (which I'm very happy with) and I assume the later AS3's are better still. There are also good offerings from Continental, Yokohama and others and you might find the recent EVO tyre test worth a look; the Pilot Super Sport was the pick of the bunch in the dry handling but finished only 6th out of 9 overall despite being one of the more expensive tyres on test.....

Oponeo and tyreleader alternate between having the best prices.

Slime is rated the highest, and only £21 for the complete kit: https://www.amazon.co.uk/Slime-18003...ords=slime+car

What's the deal with speed and loading ratings if you swap to non run on flats... IIRC the PSS tyres are not an exact match to the original specs... Or is that just horse dung..???

Thanks, I'll take a look.

I'm not looking to save money, as that would seem false economy on a £50k list car, but will take a look at the other offerings. That said, I did wince a little when I saw that replacement P Zero run flats are £226 a corner

Have run Conti's on cars in the not too distant past as was pleased with them, but will take a look at the Goodyears too.

Thanks chaps and thanks for the slime/conti pack advice

Certainly wasn't suggesting you should fit anything other than a premium tyre, the only point I was making was that the most expensive isn't necessarily the best!

I'm not out to knock Michelin either as I think they make good tyres. However, I don't think the Pilot Super Sport is quite the no-brainer choice some would have you believe, especially if you happen to do a reasonable proportion of your driving on wet roads!

The PSS are great on wet roads, and a million times better than S001's!

Interesting thread, and one I was wondering about, but hopefully not one for me just yet unless the slow puncture in the near side rear continues to be a problem and isn't repairable! MPSS seems to be the default and my first though, I liked them on my M135, but what other options are worth looking at. Care is certainly needed with The Bridgestone run flats when it gets cold and wet

I'm lost with what Michelin are trying to do with their naming, but the PS4 is 'supposed' to replace the PSS (certainly in the smaller diameters).

I don't think the 19" PS4 is available yet (must be due soon), but it is receiving very good reviews.

The PS4 is not a replacement for the PSS, there is a new version of the PSS coming next year. The PS4 is available in 255/35 19 but not 225/40 19's yet.

Michelin site is clear that PSS is for "supersport cars" and PS4 is for "sport & premium cars":

I love runflats.

Oponeo or camskill for tyres, used both and would do so again although Oponeo tyres aren't the newest (going by DOT) but then it was on a C63 and they only last 4500 miles.

[Bricktrix]

OP, its a shame that you didnt attend the ACS arranged track day (with BMW Car club) at Donnington last year.
You would have witnessed / felt in their M4, in the hooning rain, just how the front end defied physics in terms of grip in the wet.

If my new AMG is no good on the tyres it comes with after the 1st month, I will be swapping them out without question to MPSS again, as I have done with my 4 series.

Chris / Lorcan at ACS did me a very good deal on the tyres, but I was checking black circles and camskill regularly for prices.
I noted that the prices changed on a daily basis, so best watching the sites for a while to see the best deal that comes up before hitting "order".

Perhaps but if the EVO test is to be believed there are others that are better in those conditions; although they rated the PSS very highly in the dry they actually described it as "out of its depth" in the wet! It was 8th out of 9 on wet lap time, 8th out of 9 in the wet handling and 7th out of 9 on the wet steering pad; wasn't anywhere near the top in the aquaplaning tests either.

Obviously the EVO test is just one review but the impression it gave is that there are other tyres (Conti SportContact6, Goodyear AS3, Yokohama Advan Sport) that offer better all-round performance for less outlay. That certainly doesn't mean the PSS is a bad tyre, only that for use on a daily driver in varied conditions there might be better alternatives!

What tyre size & what car was the Evo test on?

I can tell you that they're the best wet weather tyres I've ever had on a 3 series by a noticeable margin, and I've had them on an sdrive and xdrive. This is compared to Bridgestone S001's & RE050a's, Conti sport contact 2 or 3's, Pirelli P Zero's & Michelin Efficient Grip's.

Don't think its as clear cut as that - no matter what the Michelin marketing people are saying.

This is a Michelin quote from Tyre Reviews:

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.


As most of us don't drive exclusively on the track it seems PSS is now redundant? As I said, it seems a bit of a mess....

Tyre size was 235/35 on 19" wheels with Y91 load rating; test car was a Focus ST. Obviously the front-drive Focus is a different kettle of fish from a rear-drive or AWD BMW but apparently it was chosen for its relatively neutral chassis balance which enabled the testers to concentrate on the characteristics of the different tyres.

Would the finishing order have been different if a different test car been used? No idea but don't really see why it would be!

Really?! I don't see why it wouldn't be! Different wheel drive, different weight, different weight distribution etc etc.

I must admit, if the 10-15% better wear compared to PSS is true, then yes they could make more sense on a road car, especially with the mileage I do. My rear PSS are nearly worn out at 15k miles & that's on an xdrive.

MPSS for me , outstanding tyre . EVO mag have always scored contis number 1 for years regardless of competition . One of the guys at work has swapped 1 month old conti 6s in 235/35/19 for MPSS he hated them so much on his Megane RS. Collect for cheap from Telford if someone wants

But if PS4 really is better than PSS everywhere except on track, then surely they're worth considering?
