Also noisier.

so the consensus is the Pirellis are worst for track, the michelins and goodyears are better for track and the goodyears spray rocks onto every one and will pit your fenders?

I've driven a 992 GT3 on track with Pirellis twice and they were very good, no complaints.

This was on a track I have many, many laps on with a 991.1 and 991.2 GT3, all on PSC2s.

The 992 on Pirellis easily beat my best lap in the 991.2 on PSC2s, and felt good doing it.

I'll know more mid season this year after I've got 10 or so days on the car. I plan on going with one set of each to try to figure out the best all around tire. I drive the car on street and track so I'll be looking at both uses.

Interesting that TireRack doesn't seem to have the Pirellis listed for the 992?

Looks like they don’t have fronts for some reason. Here are N-rated rears:

Are the ps4 homologated for the 992 gt3? They weren't for the 991 and porsche always told me can be a problem with insurance company in case accident

My car arrived with Pirelli on it but the parts department got me a set of SC2s - 2.1k / After full PPF & ceramic coating I decided not to switch them out just yet. It’s a process to get the stick on black weights correct and I would have to use solvent to remove the ceramic coating where new weights go. Figured I have a track day in April and so I ll burn the Pirelli hard them go to the SC2,s

I wouldn’t say the good years are so bad that they’ll pit your fenders, but to be safe my entire car is PPF’ed with an extra patch similar to OEM on the rear fender/haunch over the ppf to be safe.

But, if you end up with good year tell anyone on group drives to follow further behind especially in the canyons. They just seem to toss more small particles than the cup 2’s do. I’ll have the car on track soon, and I’m sure they’ll perform well.

I’m running the stock Pirellis on my 992TTS at 40F/50R in 30 degree weather here. I could be VERY wrong, but I imagine I’ll be ok with the ride quality of the Touring.

I ended up with Pirellis as well on my touring. So far my impressions are they are actually a little more quiet than the SC2s were in my 991.2.

I haven’t had a chance to take on track yet.

I would hope the pirellis are at least as good as the sc2s on track as the treadwear rating on the pirellis is only 80 vs 140 or 240 on the sc2 (depending on the version).

also the reason tirerack doesn’t show the pirellis as an option for the GT3 is because they list tbr Gt3 as needing XL load rated tires and the front pirellis are only 93, not 97 like the others.

it makes no sense to me as to why porsche would put different load rated tires on its own car.

Uh, no.

The MPSC2 has a wear rating of 180. However you cannot directly compare these numbers. They are quite arbitrary, and best suited to compare wear ratings between different tyres from the same manufacture.

If you want to directly compare the PZC4 to the Michelins, the best way of looking at it is that the PZC4 slots in between the MPSC2 and MPS4S. I like the PZC4 on my Touring as it offers more performance and response than an MPS4S, but works better as a road tyre than a Cup 2.

Porsche may have chosen to use an XL rating from one manufacture over SL from another. It may be as simple as Porsche and the tyre manufacture thinking that the character of the XL works better. The XL has a stiffer sidewall, and that might be a plus from one manufacture over the other.

The Pilot Sport Cup 2 tires on my 992 GT3 have a tread wear rating of 240. The Pilot Sport Cup 2 tires on my previous 991.2 GT3 had a tread wear rating of 180.

It's all super confusing now because all the tires have different generations with very different properties. Pirellis are the most confusing ones - most people have experience with their 3rd gen road and track tires (both somewhat sucked), then there are 4th gen PZ4 street and PZ4 Corsa track - street tires are good, like a sportier but less comfy version of MPS4S, and track tires are so-so - like a softer but also fussier version of MPSC2. But now there are updated versions of them are coming - the street pirellis that come with Turbo, for example, look like an update to PZ4 and seem to be better than MPS4S in many ways. Same with Goodyear - the latest generation is very good and rivals Michelins in many ways, while the old gens were behind. So it's important to compare specific models of tires rather than brands. Also, "Michelin is the best option" mantra is no longer the case in every situation. For example, I had a chance to compare the latest N-spec Goodyear winter tires with the latest Pilot Alpins, and Goodyear is noticeably better in dry and wet handling feel (can't compare snow performance because snow conditions were very different) - it feels almost as direct as a summer tire, maybe even more direct than MPS4S in some cases. Competition is very good, but it makes tire choice more challenging. I think at this point for most performance categories getting the latest possible generation of the tire is more important than a specific brand among the top 3-4.

At the moment, I am having difficulty just finding the correct size tires period.

I'm aware. If you read the post I responded to, he is comparing them to his 991 version which as you say, is 180, hence why I used that in my post. I actually use the 991.2 Cup 2 N1 tyre on my Pista as it has shown to be faster and better than the K2, I have also run it back to back with the 240 Connect version, and the 180 is the faster shoe. As my contact at Michelin says, it's a somewhat more street friendly version of the original 180 version. He tells me that they tend to refer to them as the "sport" and "track" version internally.
