Has anyone fitted a set of the new construction Michelin Pilot Super Sport 255/35/19 BMW OEM * tyres....the ones homologated for the front of the new M3/4? (275/35/19 for the rears).
If the new design tyres are partly responsible for the reported impressive front end grip of the new M3/4 then they may well give some improvement for the E9x M3 as well.

Interested to hear about this. I need front tires soon

[Kosta1968]

I have 255/35/19 PSS on my car but I'm unaware of them being a special bmw spec. Nevertheless my opinion is that front grip has been greatly improved over the stock OEM 245/35 PS2.

This from Chris Harris:
"We had 19-inch wheels (standard in the UK) running the standard Michelin Pilot Super Sports. Incidentally, that's a completely new tyre with a bespoke aramid belting and compounds specific to this car only. Front axle grip is alarming at first - you push, it grips, you play silly, and it still grips. On very technical roads, nothing in the class would see where it had gone (in the dry) for that reason alone."

Looks really interesting...I'm inclined to take off my current 245/35/19 PSS tyres (still with plenty of life) and try a set of these new spec tyres.

We do have a part # for the BMW OEM version 255/35R19 PSS with the star branding. None in stock yet, and they have not given us detailed specs.

As always with an OE-spec tire, I expect BMW to tout it as vastly better than the 'normal' version without disclosing anything specific that makes it unique.

I had an email exchange with their tech support which didn't really have what I was looking for and they suggested I should to call them for further info.
So i'll call them Monday and see what they say.

I talked to Michelin today and they couldn't really help in that they haven't run an E9x M3 with these tyres and they have no way of knowing if the changes they made to the star rated OEM tyres for the new M3/4 would benefit the E9x M3 or not.
I guess someone will have to try them and see.

Interesting thread Senor, I was thinking the same. I bet Michelin do know as they have all the data.

The 255 / 275 combo would fit better on the 359M wheels. Most car makers run 255 on 9 inch front wheels and 275 or 285 on 10 inch rears.

Somewhere I have the details of a Michelin tech guy from Goodwood FOS last year. I'll have a look for them.

It would handy if you could talk to someone with better inside info.
The person I spoke to was a bit reluctant to give (or didn't know of any) details of the BMW * rated PSS tyres except that Michelin had constructed the tyres to a particular BMW specification with a different carcass and tyre compounds
If the 255/35/19 size had a stiffer sidewall (than the current 245/35/19 PSS) that would be interesting - something with a faster response to steering input.

[Ant Man]

Sorry mate. Had a look through the motorsports contacts and nothing for Michelin. I'll have to check business cards but I may not have the chap's details I'm afraid.

So in other words, compared to the non-OEM spec Super Sports already out there, there is nothing really special about these.

Interesting. Did they purport to do anything to the 275 rear?

In most cases the car manufacturer and tire manufacturer resist disclosing what changes were made when they designate a tire as original equipment. Occasionally some differences may show up in the specs, but those are usually minor.

Unless they want to come out and say "We changed x y and z to make it better," I assume it's 10% tuning and 90% hype.

If you're replacing less than a full set on your new car, get the OEM version so that it's an exact match. Otherwise, I don't usually worry too much about it.

[W12x]

Have the regular PSS in OEM size on my car right now, would love to test the new BMW special PSS tires against regular PSS in the same size....but it would cost too much lol.

If anyone want to sponsor me two set of 255/35/19 275/35/19 PSS tires BMW and vanilla I would be happy to put them on and do some tracking and report back lmao

[StealYourFace]

The front OEM tires have a rounder contact patch and the oem rears have a typical broad/flat contact patch. So basically they built some camber into the fronts.

Hey, I only found a BMW spec PS2 on your website. Am I missing the BMW spec PSS or is it not available yet?

[BrewRifle]

I'm also interested in these new tires. Any updates, Ben?

Found the article here -

http://michelinmedia.com/news/michel...ration-bmw-m3/

I just emailed Brian (info at bottom of the page) inquiring about purchasing these through a supplied vendor.

Not in stock yet, so not on the site. If you call me (877.522.8473 x4660) you can order them at $270 each. They would be delivered when stock becomes available. That might be later this month, but we do not have a definite date yet.

For people reading this after 8/5/14, the $270 price is current as of this writing, but may change in the future.

[BrewRifle]

here is the response that I received from Brian at Michelin -

The 255 is MSPN 90967 will go into production in late-August and will be
available in the market in late Q3.
The 275 is MSPN 69959 will go into production in mid-August and will be
available in the market in late Q3.

Neither tire is star-marked for BMW

Thanks for getting back with me but this might have to wait til the next round of tires we get. Our rears are pretty bald right now so im looking to get new tires ASAP.

I have PSS from the F8x M3/4 on my car. I'll report back with anything that jumps out, but so far they feel like normal PSSs.

It will be interesting to hear what you think of them. I guess it would unrealistic to expect a quantum change in performance over the existing PSS tyres.
Myself I don't really like the feel of new tyres...the high tread blocks tend to lean slightly on initial direction changes which can make them feel a little mushy. I think they are at their best once about a third of the tread has worn away.
