• The Pilot Sport 4S is the higher-performance model and the true successor to the Pilot Super Sport. It will be available in both OE and replacement fitments.

With a lineup consisting of 19” and 20” wheel diameters only (with the convenient exception of 245/40R18), the Pilot Sport 4S is scheduled as a two-phase launch, with 35 sizes launching in March of 2017 and the final 23 sizes available one year later in March of 2018.

Expect replacement fitments of the Pilot Super Sport to phase out approximately in-step with the phase in of the Pilot Sport 4S, but the Pilot Super Sport is not completely going away, as production of the OE fitments will continue. So if your car comes OE with the Super Sport they will still be available.

A full test including the Pilot Sport 4S is on the schedule for this spring, but what we know so far is compared to the Pilot Super Sport, the Pilot Sport 4S is similar on the road and in the dry, with small improvements in refinement and marginally-improved dry performance. The biggest gains over the Pilot Super Sport come in rolling resistance, and more notably, wet performance, where the Pilot Sport 4S has taken an impressive step forward in measured testing. The Pilot Sport 4S also retains the 30,000 mile tread life warranty of its predecessor.

Though not yet live on the website, the Pilot Sport 4S initial size lineup has been built in our AS400, so customers may preorder in anticipation of what will likely be very high demand.

The global product launch is currently taking place in California, with media influencers from around the world in attendance.

If I can help with anything let me know.

2014 Cayman S w/ the 20" stock rims. I believe 235/35ZR20 and 265/35ZR20 if I recall correctly are the default sizes

Me too. Tried to verify but apparently the news has crashed your website under the onrush load... :)

the final 23 sizes available one year later
A year? That's incredible. Hopefully the 20" size for my car will be lucky enough to be in the first iteration! Or the 19" on my M3 I was hoping to be able to replace this spring. Perhaps I'll have to go another direction, because those tires are toast! :)

Given the apparent slowdown (halt?) in production some time ago of the MPSS in many sizes, I can't believe Michelin isn't concerned about the negative impact of people not being able to get either of their high performance tire lines from Michelin in the size/star/N1 designation they need. At a minimum it's going to push folks like me to try options I otherwise would never have considered.

Screwy. Did they have a factory burn down?

That is standard practice when they introduce tires. There is no way they can make every size at once. You can give me a call anytime and I can check. I do believe the Cayman S 20" sizes will be in the first batch.

Without a 265/40/19 in their lineup, guess i can forget about this tire for a 981S.
Since you have gotten a price on the new michelin, do you have pricing on the Conti Extreme Contact Sport in the mentioned size?

Jim, thanks for the update !
I hoped ps4s will be significant improvement over pss at the dry.
but it looks like it's not :(

never heard about 30,000 miles warranty - i guess it's USA thing only, isn't it?

Yes, just a slight improvement in the dry but much better in the wet is what we are seeing at this point. We will do a full test later in the spring..

Porscheguy944,

Take a look at the Bridgestone RE71R for the best Extreme Performance tire. They are 258.50 front and 291.35 rear and they are going to give you the best handling in a street/track tire. If I an help let me know.

I think those 35 sizes that launch in 03/2017 are listed in the first post.

That is a great point, and thanks! I completely missed the point that the listed sizes were the 35 coming out in spring, the other 23 aren't included there. The size I need (245 & 265/35/19) is indeed in there! Good news, and I can wait since I don't drive the car that much in the winter anyway.

:thanks:

Jim,

What is the usual amount of time that passes before Michelin begins to release tires that have OE Markings (compared to the non-OE marked versions)? Trying to get an idea as to when I should start to check to see if N-Spec versions are starting to be stocked. (Michelin indicates that there absolutely will be N0 versions of the 235/35-20 and 265/35-20)

They only receive the N spec when they are used as original equipment on the car. That would be a question for Porsche. There are no N spec tires at this time.
