I hear ya, I think there might be a misunderstanding. Don’t worry, I can afford to maintain this car. I just want to know what’s really a worthwhile expenditure and what isn’t. That’s all.

After all, I just purchased $3000 Soul sports cats, and obviously that wasn’t a “necessary” purchase

I have to say, the indoctrination in this forum into Porsche fanboyism is rather fun, though. Nice to hear these perspectives.

I know several guys that replaced the Sport Cup 2’s with Pilot 4S’s on their GT3’s for similar reasons (they just don’t admit it on RL &#129315. I’m picking up a C2S tomorrow and going to visit my son in the mountains but it will be below 40 degrees so will have to take another car maybe so I think you have a legitimate question.

Maybe it’s possible but it isn’t ideal. The Nissan GTR comes with ultra high performance A/S in some markets.

I had Bridgestone Ultra High Performance A/S on a previous awd sedan when I lived in Chicago a few years ago, after 1 winter season, the tires still slid all over the place in winter. The 2nd season onwards were a disaster to the point I wouldn’t drive the car whenever there was snow on the ground. Never again.

For what it’s worth to the OP, consider a nice set of Alpins on some used OEM rims for colder seasons OR put your new snows on your existing OEM rims and get a nice set of HRE or BBS or ??? for your OEM N spec tires. I live in a climate that I won’t drive the car for at least 4 months a year, yet I still used to have properly specified tires for shoulder seasons (late fall and early spring) with the best part being I had a two different “looks” for the car and with a season change - quick swap that I would do myself and bang...new look. Btw Carcam is right...I have Cup 2s on my GT3T and in November mornings can be like riding on hockey pucks...so Michelin PS4 being installed come spring.

I would also like to see AS for the 992. We have many days here where the Temps are upper 30' to lower 40's in the AM, then near 60 in the PM.

i know money/convenience is important, but having the winter tire/summer tire combo is really important for a performance car. or just use only summer tires and don't drive it in the winter.

you'll get into trouble if you use all seasons in the winter, that extra money isn't worth it.

Pilot as 3 or 4.

They are excellent. If you arent looking for the last nth of grip (which hopefully no one is on the street) or feel, all seasons are great.

Why do some people fail to realize that not everyone drives the car the same way or has the same wants from a car?

If some loser tried to lecture about nspec tires, id tell them where to put them.

Get a good hi performance all season and enjoy

So here are Michelin All-season Ultra High Performance tires (not yet launched for the 992): https://www.michelinman.com/tires/pi...-s-3-plus.html

Note the comments that they don’t work well on snow or ice. However, they would be okay for cold weather. I get that it’s a hassle to change shoes for winter. My dealer in Switzerland would store my snows, so all I had to do was take it there and they would change them out while I waited. We need that here!

When I traded my 991.2, I sold the snows and decided to park the 992 on the cold days. I’m in southern Delaware and the winters here are mild, so I can take it out on nice days, Yesterday was 55 degrees here.

A couple of things - as pointed out previously you don't add wear a tire when it is sitting in a garage or basement. Considering how fast HP tires wear out, the extra cost of the winter tires becomes zero after a couple of years. The additional cost of a second set is therefore the wheels and whatever switchover/storage costs you incur. DYI and it is a bit of labour twice a year.

For people in places without severe winters, AS can work for the off-season. It would still require a spare set of wheels or a twice yearly mounting on rims. I agree that in warmer weather, using AS tires on a sportscar defeats the whole purpose of the car.

All-season fitments for the 992 do not exist. Fortunately, Michelin and Pirelli have excellent performance winter offerings in the Pirelli P Zero Winter and the Michelin Pilot Alpin 4 and 5. Also Continental has excellent Performance Winter tires. These are great at 50 degrees and below. Great performance and traction, not very loud, and not necessary to be in snow to justify their existence. Great channeling for rain as well. I’m a huge fan of my Michelin PA5s. If you can afford a 992, you can afford a set of tires for December through April and a set for May through November.

Thank you. Every year this question comes up, and there’s the usual list of people who think it’s heretical to put anything other than summer or winter tires on a 911. They completely miss the point that some people live in climates that aren’t suitable for winter tires in winter. It’s 35F and damp driving to work, then it’s 65 and dry on the way home. And not everyone wants to ‘drive the pickup’.

If you live in the snow, yes the answers obvious. Here’s the rub for the OP - The Bridgestone Potenza RE980AS may not fit the rear. I haven’t checked.

Believe it or not, people put AS tires on their GT3s. I know that will make some people clutch their pearls, and suck air through their teeth. 🧟‍♀️

I own a 991.2 C4 that I daily drive in Chicago 4 seasons. The idea of using AS tires is completely unappealing, but that's not why I'm posting. I also own a Macan with those beautiful 20 RS wheels and AS tires. The first time I drove in the snow I couldn't believe how poorly they functioned. I immediately bought new snow tires and wheels. Point being, those wide tires on Porsches (911 and Macan, even with AS tires) perform poorly in the snow, without dedicated snow tires. If you're driving in the cold, but without snow, maybe you'd be ok.

Anything tire related seems to draw a lot of controversy. Maybe more than a Burmeister v. Bose discussion. Living in Georgia we see (for a very limited time) a climate pattern with the skews described in an earlier post. But frozen precipitation is pretty rare and when it happens it triggers mass hysteria. What doesn't compute for me is how AS tires offer a strong value proposition in such a climate. There is very clear evidence that in snow, winter tires (and AS to some extent) offer evacuation channels that are needed for safe operation. But where I find the evidence lacking is in the assertion that summer tires have (materially) degraded safety characteristics simply "when its cold". Tire manufacturers will say that summer tires are ill advised in temps below 45F. But I would really like to see some empirical evidence that supports this conclusion. I understand that in theory using materials that are more resilient in colder temperatures might mean more traction but I don't know that the ground truth of this is compelling enough to buy them in generally milder climates. In my area, everyone I know runs summer tires on their sports cars year round without issue.

Before I garaged my car and went into a depressed, Porsche-withdrawal state, I went on a farewell drive at 37 degrees.

It was dark and dry, but it was still below the recommended temp (I’ve been advised 40 degrees). I drove like an absolute crazed madman through the countryside. I was doing launch controls, flooring it and doing curves like it was my last day on earth.

The car held to the ground like it was glued to it.

However, on the day I drove it to the shop it was 16 degrees and the car had zero traction. I even experienced my first “acorn effect” which freaked the hell out of me.

There is obviously a temperature below which summer tires aren’t safe. I doubt it’s 45 degrees though

If you don't mind the fact that all season tires are not the best at anything and are willing to compromise your cars handling, then someone will eventually make a tire that fits. As long as you understand that stopping distances for AS tires are much greater than snow or summer tires, let alone handling then sure, you can put anything on the car you want as long as you understand the trade-offs. I drive snow tires in Colorado where we have 70 degree days in the winter along with single digit days and ice and snow. I would never run AS tires on ANY car, let alone my Porsche.
