Wheels and Tires for GT3

[murphsea]

Hey everyone,

Looking for some ideas with regard to tires and possibly wheels for my GT3 Touring.
My touring is coming with the PZero Corsa tires which I believe is the equivalent of Cup 2 tires.
I'm slightly concerned with the wet road performance of the those tires.

For instance, I'm going to drive down to Werks Reunion at Amelia Island from Charleston and I can't remember any drive down to Florida where I haven't run into heavy rain at some point.

I'm thinking I should put regular PZero or Pilot Sport 4S tires on it if I'm planning of doing any trips with it.
Normal day to day it's easy to know if it's going to rain and to just take out another car but on a trip that's different.

Would love to hear the thoughts of people who've run the Corsa or Cup 2 tires and if they'd recommend a better wet weather tire.

Also, would be interested on hearing about second sets of wheels that people have bought for their cars.

Thanks in advance,

Sean.

My opinions and experiences -

Before I share what I've done on my Turbo S and the Cayenne Turbo, I'll say that I've had far better overall results with Michelins vs Pirellis.

I do have winter wheel & tire sets for both those vehicles. Rain (standing water, actually) is a concern on MPSC2's, but for me the cold is the bigger potential problem. Extreme performance summer tires are unsafe in the cold - no grip and tough to warm up. They'll also crack (sidewalls mostly). Don't know what Pirelli's policy is but Michelin generally won't warrant the tires if they've been subjected to movement in very cold temps. (I've attached a Michelin MPSC2 doc given to me by a Porsche tech. The last paragraph addresses the cold ambient temp issue.) However, I would think temps on the very cold side are not usually an issue in Charleston or your planned trips further south.

I'll respond in a later post here with what winter tires I have on the two vehicles mentioned above, but I think if you're cautious, rain will not be a problem. While standing water is a very big potential danger, slowing to speeds well below the limit should give you a decent safety margin. If you're in a downpour or there is a lot of standing water, slow down which is wise advice for any car and any tire.

Also, not sure if your new GT3 Touring has a "rain" mode or not. The Turbo S does and it is a ridiculously de-tuned mode. It feels like what I would imagine a 1960's Rolls Royce might drive like. Soft ride, shifts that are almost totally imperceptible, a brutally suppressed power band, etc. Want to talk about a Nanny? Wow! If I had to drive the TTS in that mode all the time it would be gone in a flash. I think a Yugo has more power. (Assuming there are any of those still around and still running.)

My thoughts are that if the car is in rain mode (assuming yours has one), you going to have to go out your way to force it out of control, such as turning the wheels radically and intentionally driving straight off the road.

The GT3 Touring only has Normal, Sport and Race modes, no Rain mode. I've had the Rain mode in prior 992 911s and it was great. I really tested it out at the low grip track at the Atlanta Experience Center and it was almost impossible to make it lose traction.

I've had Michelin PS4S tires on nearly all my prior 911s. Had a used 991 that I bought which had PZeros on it and after changing to PS4S tires it was so much better. I even have the PS4S tires on my SVT Lightning Pickup Truck .

I think I'll go that route and save the Corsa tires for the proper hot weather and dry conditions which we have a lot of during the summer in Charleston.

On one of my trips south I saw what was remaining of a Porsche 911 which hydroplaned on the on ramp to one of the interstates. Maybe he was going too fast but I'd rather be safe than sorry.

I think that's the wise move. I don't see how you can go wrong by switching to the PS4S tires for winter. I've had great results with them on other vehicles and they will certainly give you an increased margin of error for both wet and cold situations. Again, considering where you are now living, they will fit off-season driving quite well imo.

Regarding the "Rain" mode, I kind of thought that Porsche's GT cars would not have that. Thanks for confirming.

My winter tire/wheel sets are from Porsche. The Cayenne Turbo has Michelin Pilot Alpin 5 SUV "N0" winters on smaller 21" diameter wheels which is what Porsche furnishes. Tires are German made Porsche spec. (I don't think anyone makes a true 22" winter tire.) The Michelins are fantastic tires for winter.

The TTS winters are Goodyear M+S Ultra Grip Performance "NAO" Gen 1 (also made in Germany) and are also excellent. I've been greatly impressed with the German made Goodyears Porsche is using, both standard and winter.

I am entered for my 5th Amelia Werks Reunion on March 3rd, 2023.

I usually go down on the day before except for in 2021 when a big rain hit the area. I left home early on the day of the event and missed the rain. I arrived within an hour of guys that drove down in the rain storm.

I now have my new 2023 Turbo with new Pirelli tires. It's 315/30/ZR-21 on the rear with 255/35/ZR-20 on the front. They seem to work well at home in wet conditions (not flooding rain as before). Of course, it's a 4-wheel drive car.

I will park with a Carpokes decal on the dash. I always bring two folding seats (my wife stays at home).

I think we should all go out together for lunch on the Moderator's credit card. Just kidding .

The Carpokes Guys need to do something and take pictures? I have a good camera.

Beautiful looking car. I'm usually there pretty early. I'll create a new topic where we can post pictures of our cars that we're taking to Amelia Island (whoever is going) and we can post to that topic to find a time and place to meet up.

I'll put my carpokes decal on the dash too.

Spoke to someone at the Michelin factory yesterday because I was finding it hard to get hold of the rears.
They're on back order and aren't even scheduled to be manufactured in the next 30 days.
Went with the Goodyear Eagle F1 Supersport tires (recommended by Porsche for the car) which are the Goodyear equivalent of the Michelins. They seem to compare favorably and I think that's what my 992 C2S came with from the factory.

Amazing that the tire shortages are continuing.

I think you'll like the Goodyears. My '22 Turbo S came from the factory with the same as the ones you're getting (Goodyear Eagle F1 SuperSport Max Performance Summer - Porsche spec "NAO" ). They're made in Germany, which is a plus in my book.

I’ve been hearing positive reviews on the Goodyears for both road and circuit use. My 992 GT3 is still on the water and was fitted with Goodyear Supercar R tires, so looking forward to experiencing them in conjunction with the double wishbone front suspension.

My 991.2 GT3 arrived with factory fitted Dunlops and I was pleasantly surprised by their performance and tread wear in comparison to the Michelins I had on my previous 997 GT3. It seems that all N Rated tires work relatively well on the street with some lasting longer on track than others.

If possible, I would like to hear about the Goodyear Supercar R's once you've had time driving on them. I'm assuming that will include track time so info on that would be great if it happens.

I've used the MPSC2's and Dunlop Sport Maxx 2's (Porsche spec for both) and I like them both. While track wear is never ideal, they both perform well. Last year I went with solely with Michelin because I could get them. The Dunlops were mostly not available and when they were it was either front or rear, rarely both, and the prices were through the roof, especially for fronts (245/35R20) which went from ~$420 in early '21 to ~$475 later that year ending at ~$619 last August. I have not priced them recently so maybe pricing is coming back down to earth a bit.
