Question Michelin Pilot 4S

How many members have these tires on their M6 GC’s?
I don’t love the Pirelli P Zeros and am looking for an alternate, and I think the Michelin Pilot Super Sports are discontinued (not 100% sure)
From what I read in the internet, these MP4S are awesome and I’m ready to pull the trigger on new tires that don’t slip all the time, and trigger the traction control. I’m planning some minor mods like a tune and a CAI...

Opinions appreciated!

I just switched over to the 4S tires from the Michelin Pilot super sports on my M6 GC. I really like them so far. They are a lot softer than the MPSS and my butt dyno tells me they are maybe 15% grippier. Would definitely recommend as they are nearly the same price as the old MPSS. I think I'll probably switch over to Cup 2 tires after, cause traction is still an issue...

You can probably still get MPSS from some dealers, but the price difference doesn’t doesn’t justify when comparing to MP4S. Had the OEM Pirelli in my M6 Coupe and changed for the MP4S - what a massive difference, you wouldn’t think you are driving the same car! Traded the Coupe for a near new Gran Coupe last week, and when I realised the GC was on P-Zeros, there was only one option: swap the tyres as part of the trade. Amazing tyres, with P-Zeros the traction control was lighting up like a Christmas tree through the first 4 gears, the Michelin’s have suddenly fixed this problem. Now I’m thinking that perhaps 600 hp is not too much for a 2-wheel drive car after all, with Pirelli I thought that 575 was 100 too much...
265/35x20 front, 305/30x20 rear, no issues with gear shifts or anything else. When you make the change, find a wheel alignment guru who understands a bit more than factory setup, makes a big difference and when done correctly, improves tyre life time quite significantly.

+1 and I also went 10mm wider on front and back when I put the last set on. Very happy.

I’d stick to the original size fronts, 265 - wider front tyres will most likely increase understeer, and since these cars are not the sharpest tools in the world due to their weight, you won’t gain anything from going wider. But rears yes 305, improves traction. You’ll be ��

Yep - there's another thread here on the slight width increase rather than spacers (no rubbing) ... a little more rubber on the ground for better traction and a little extra sidewall to help protect the wheels from curbs.

Wow, 305’s on the rears!
Now we’re talking!
Definitely no rubbing or issues?
Proper fitment on stock 601 rims?

Definitely no rubbing with 305s. And looks better than the original 295s. Not sure about 601s, mine are 433s but should be the same size. You won’t be disappointed!

better get your butt recalibrated. I heard they were only 10% gripper.

Good decision! Next stop wheel alignment, I would recommend... Find someone who knows what they do, changes the car (for better), especially rear wheel alignment. My guess is that any dealership alignment wouldn’t touch rear alignment because it’s a bit of a challenge, but soooo worth it...

Why is this necessary guys? And why does BMW not recalibrate the rear end when tire sizes are changed -- what makes it so difficult/policy oriented "I can't touch this..."? spikespiegel MelbourneFinn

Got the MP4S a few months ago. Nothing bad to say about the tire. Will stay break loose under full acceleration in 1st gear on the street. We'll see how long this level of grip lasts.

The MPSS on my C6 was a great street tire that could be tracked nicely short of R-comps. Probably got 10k miles and a few track days before it became really obvious that the grip was gone. I'd assume the MP4S is at least as good, but the M6GC is a much heavier car that I don't plan to track so who knows.

Thanks,

Any car will have various adjustment options available, depending the settings, they either work better or not so well. As to why BMW doesn’t set it up “perfect” from the factory, well, who knows, but the experience has showed that they don’t. And almost no car manufacturer, for that matter, with a possible exception being limited production series super/hyper cars - or what do I know, never had a chance to compare “factory setting” Koenigsegg with a “non-factory setting” one...

But make no mistake, this is absolutely necessary if you want to get the best out of your car - any car!

So what sort of stance guidance do I need for the mechanic working on the vehicle? Are we speaking of just adjusting the camber? Or when you say "set up" the vehicle, what are some of the stats you speak of that ideally position the car to perform its best?

Thanks for the knowledge! MelbourneFinn spikespiegel

Camber, caster, toe-in - the whole nine yards... To be honest, I don’t have a spec sheet of what the exact settings are that I’m running at the moment, but if the mechanic doing the alignment doesn’t know what the ideal settings for you would be, he is not the right guy for the job... Instead of degrees he should be asking you questions like how do you us the car, do you prefer precise steering over comfort, tyre life over stability etc. - you get the idea? There are more than one set of settings for every car, depending how you intend to use the car and what your preferences are. Guess I’m a lucky one as I have found someone who intuitively knows exactly how it should sit, based on my preferences (balance, precise feel, “turns when you turn the steering wheel”). But I don’t think you want to ship your car to Melbourne for wheel alignment ��

Understood MelbourneFinn; it's a rare breed in my neck of the woods. And, what astonishes me the most? I live in the same town where BMW has its PCD. Can't even find a well-sorted M6 in this town either lol.
