I will be in touch with michelin to have their point of view about fitting the mp4 with PSS ou PSCup tyres.

anyway is there someone here who is considering EBC pads (yellow or blue) for oem steel pad replacement ?
I'm sure Michelin will do it, but the conversation you need to have is with McLaren to determine if your warranty will be affected!! I would love to put Cups on this thing, oh my God the grip would be stupendous. Edit: maybe too much grip, without a harness!

the pilot super sport are always winning comparison tests , they are as fast as the cups and are more for general purpose

i am not very satisfied by the feedback of the stds P0

corsas are quiet expensive, not so quick (vs michelin) and not very tough

There is conflicting info about SS vs Cups. I cannot see how they are as fast as Cups, based on tread design. They may be easier for a journalist driver to get into ideal temp zone, as a guess. I have not driven them. I have a lot of time on Cups - they can be tricky to manage temp, but when they are "in", they are awesome. I did read somewhere that Michelin says despite they're advertising, SS are not as fast as Cups.

i find now that the SS are available (235/35/19 and 305/30/20)

i'll manage to have the answer from michelin to know the true difference between the both.

I am sure SS are bether than corsas arent you ?

Don't know. I have not driven either SS or Corsa yet. But I do know Michelin make outstanding tires and always my first choice. They have a similar mission - both track oriented but with more everyday tread usability than the Cups. But who knows which is better on the 12C. Again, I wouldn't order them without getting commitment from Mc that your warranty will be OK.

i would keep to the standard AP pads they are well capable

regarding tyres you should be ok after 3 years but dont think McLaren with warranty other tyres due to sensor settings etc, im not a Pirreli fan but they have been tested with these tyres on from the start and can lap the top gear track in 1.16 they are more than capable and if you think you need sticky tyres your not driving it hard enough. 1.03 lateral G

The point is that the Corsas are very expensive. If you can get Michelins, which are very possibly a better tire, for less money then why not (assuming they are blessed by McLaren). I'm still having trouble understanding why the electronic systems would be incompatible with a different tire. In theory, only the level of grip changes and that happens naturally in diverse weather conditions and levels of tire wear, anyway. So, can't see why that would throw TC or ESC for a loop.

The Michelin Pilot Sport Cups, specifically, will also last longer seeing regular track duty than the Corsas - I can all but guarantee it just by looking at the tread block depth and design. You don't have to be the Stig or Chris Goodwin to see the benefit of a true track-biased tire like the Cups. Any experienced track enthusiast will notice the difference and realize the performance and durability gains. I say durability because deep tread blocks are just not capable of sustaining lap after lap of hard driving. The tread blocks literally melt and chunk to pieces. You can easily destroy a set of brand new street tires in a single track day.

In my honest opinion, McLaren should allow any properly rated street tire to be fitted without voiding the warranty. They could even limit it to the major brands, if they are worried about some homegrown tire they've never heard of. Obviously slicks and racing tires are a different ball game altogether and I would not expect a blessing for those.

I fail to see how tyre choice could possibly affect warranty?

That notion is akin to McLaren depicting the specification of the tarmac you can drive on, which they don't!

You are therefore free to choose the tyres you want and the road (or track) surfaces you want to use them on.

I also don't think that the TPM or any other systems will be affected either, I'd just suggest that you ensure the tyres are inflated with nitrogen as that is what McLaren are now doing to combat TPM error messages through temperature / pressure variations.

I'd really love to see how well Cups are performing on the 12c !

But it's a known fact that car manufacturers can "glue" their warranty to the use of specific tire models. Aston does it, Ferrari does it. It could also be the case with McLaren, something that certainly needs to be clarified in the future.

As for the electronics (ABs, ESC, TC, CBC), it's not so simple anymore in today's supercar world. Specific tyres are developed for a specific (super)car and electronics are highly optimized to work best with this specific tire. Of course that does not mean, that you cannot put a different brand/tire model on the car and it does not work at all, but chances are very high that it does not deliver optimal performance in the last 10-15% near the limit.

One tire can deliver outstanding performance on car A and simply "not work" on car B. I'v seen this so many time over the last years. For example Michelin Cups seem to not cope well with the ZR1 whereas they work like a charm on a GT3 RS and most BMW's. Same story for the GTR.

So, in the end this *could* mean that the Cups may not work very well on the 12C, especially since this car seems to be so highly dependent on it's electronics.

However, if Mc Laren does approve the use of Michelin Cups, I'm sure somebody will try them out very soon (Gallardo62 ? :D )

PS: Personally I don't like Corsas. They caused quite some problems on different cars in the past. Too bad Mc Laren went this route but then what do I know :)

I agree..I do not believe warranty can be affected by a tire preference...

I agree completely that warranty should not be effected, besides McLaren uses Michelin's on their GT3 racer (different size wheels and set up of course) and Michelin is one of the sponsors...

Mclaren during the cars prelaunch decided tyre wear was comparatively low so speced a softer compound whic resulted in a dedicated tyre. This will be replicated IS my guess by Michelin, hope so as the current tyre is poor when cold and on tight turns.

The PSS is certified by BMW M to do 10 laps under 8minutes on the nordschleife with the m5 v8 tt

michelin says it can achieve twice...

I shall have to have information this week
