I have the Cup 2s and will be switching as well. I’ve read the AS3 is better on the street at temps below 70. I think the only place one may notice the Cup tires better is on a track after a good warmup.

That's pretty much my dilemma

Winters here are pretty mild, not sure I want to give up that much grip for a few weeks a year
AS3 are 500
PSS are 300

They both seem pretty equal when warmed up, no sure I want to sacrifice the launch
with the harder AS3

I run AS3+ during our mild (~ 40º) wet winters, just put back on the stock PSS. The AS3+s are much more forgiving with tire hop, are a touch quieter and still have plenty of grip, IMO. Since I don't track, I would likely be happy with AS3+ year round. Just my 2¢...

Have run PS3+ A/S on my '14 and now my '19 GS.

Year round, much likey

Plus one on the A/S 3+. I immediately replaced the OEM's with these in non-runflats and could not be happier. Much more quiet they don't throw gravel all over the car, and just offer a smoother ride our weather beaten roads in Montana. I think the softness of the non-run flat may help prevent stress on the wheel. I've pushed them pretty hard and they have plenty of grip. They are obviously better than the OEM's at any temps below 60 degrees.

I actually went with the AS 3+ ZPs, great ride, and for what I do plenty of grip. Plus the added bonus of no flats.

And here in NC, we can be 80 one day and 40 two days later.

We just put the run-flat (ZP for Michelin) version of the A/S3+ on my wife’s Stingray. Quieter than the PSSs, and much better traction under about 60F. Not willing to trade a little noise for the run-flat capability, as both my wife’s Stingray and my Z06 have had flat tires. Driving to a tire shop or dealer really beats getting a flat bed to haul it in for a tire repair or replacement.

Our 2017 Z51 has about 18k miles on the AS3+ ZP, and 10k miles on the factory PSS ZP, we switch out every Fall/Spring with a second set of wheels/sensors. I've done hours of really hard driving on back roads in Texas and New Mexico with the AS3+, if you need the little extra grip of the PSS on public roads, you're driving like an idiot. I only keep the PSS because I do some autocrossing each summer and small increases in grip can be the difference between good times and mediocre times. Also, the PSS will stand up to the heat of competition driving better, but that shouldn't be an issue on the street.

The PSS cost about 10% less and last about 50% longer, so your tire-cost-per-mile gets cut in half. Below about 50'-60', the AS3+ grip as well or better. I just tested them in 3 1/2" of snow on my driveway, worked pretty well.
The AS3+ should be the standard factory tire, with the PSS only as an option.

Chip,

I have both PSS and AS3+ sets, and I just put the PSS back on my car yesterday. I've been swapping them back and forth every 6 months for the last 3 years. Even though it was 70º today, I had less grip on the PSS than I did on the AS3+. They were much easier to break loose. The only time the PSS is better is when they are very hot.

It's also harder to get heat in the PSS. On my previous drive on the AS3+ at the same temp, the pressure increased from 30 to 34-35 psi at the end of my 30 mile commute. Today, the PSS only went from 30 to 32 psi at the end of the same commute.

I really like the PSS, but only during the hottest months of the year. If you're only going to have one set of the tires for street use, I think the AS3+ is the superior choice for 8-9 months a year in our climate. At any temp below 70º, the AS3+ is vastly superior for street use. They're pretty damned good when it's hot too, just not better than the PSS.

Another vote for the AS/3+..

I just purchased a set of AS3 zips great tire wont be going back to stock tires anytime soon,

Switched to the AS3+ at 27k miles. Much better traction in 40-60 degree temp range (not to mention below 40), a bit quieter, less Ackerman effect at lock.

Temps have been 80 here in the day and 40 at night, so been a good choice for me. Don't notice any real difference canyon carving.

Tks everyone - appreciate your input

Went with the AS/3's

I have wrestled whether to go with run flats or not. They can save you a lot of hassle if your tire issue is a typical non-side wall nail puncture and your within range of a decent tire shop or service station with mechanics. If your out on extremely remote roads where I live in the intermountain west and you have a problem other than a simple puncture on either ZP or non ZP tires your going to be there awhile and better hope your in cell range.. My biggest fear is where I'm going to put the car if I have to pull over for even a look see. Many roads have little to no shoulder so your in the weeds to get it off the road and hopefully its a flat area. It's just the price we pay to drive a car like this on the back roads. Many never do that. If I lived in or near a big city I'd probably have run-flats and would have left the PSS's on until the wore out but with the roads I have to drive on, the ride quality and noise level of the non-ZP Z/S 3+ blows the OEM tires away. All I can do is carry the best tire kit and hope. Most of the new cars out there now have no spare or run flats and are running around with cheap repair kits so I guess I'm not alone.

I just put AS3's on after 15k miles on the PSS. I noticed that the car feels a lot different. The steering is lighter, the car doesn't tramline and the tires do not chatter. That being said, I do miss the grip that the OEM's offered.

I stayed with run flats for piece of mind. I've had two flats and was grateful that I could drive home.

One of the biggest reasons I changed though was I like to drive the car in temperatures below 40 degrees.

The car is easier to drive but you are giving up grip.

One "unadvertised feature" of the runflats is that you can go a long way if the tire is already ruined, or you're willing to ruin it to get someplace.
We had a sidewall cut (unrepairable) on a Michelin runflat out in the boonies, just drove it until we got to a Discount Tires that had a replacement in stock. That was only about 30 miles, but I've heard of people going as much as 400 miles on a flat (55 mph max) until they got home. I couldn't find anyone who actually had a runflat come apart while driving, though I'm sure you could make it happen with enough speed and distance.
With runflats, you stop when you choose to stop and not when you're forced to stop.

The new AS+3 are in the garage waiting till I return to be installed.
What can I expect to sell the O E M tires from my 2019 GS with 1800 miles on them for?

badhabit_wb

Dead on! For what it's worth I've had 2 sets of the pss and multiple sets of the cups. For the street the As3+'s are the best tire by far.

This year, I ran a dedicated set of the new A/S 3+ ZP’s on my GS during the cold months (Nov – mid April) and it was just a week ago that I switched back to the summer PSS’s. Glad to get the PSS’s back on!

First things I immediately noticed after putting the PSS’s back on were how the ride was firmer but harsher, the turn in was much sharper, the steering was far more responsive, and with the temps in the 70 – 80’s the grip was way better (as to be expected.) Also, as mentioned by others, the PSS’s pick up everything on the road and throw it up against the underbody/wheel wells.

The new A/S+ ZP’s were fantastic this winter. My GS is a year round daily driver, and it was great to be able to: 1) push the car hard in the cold without sliding all over the place, 2) not to have to worry about my tires freezing and cracking from sitting out in sub 32F temps all day, 3) get decent traction with snow or ice on the roads. The all seasons seemed much softer, smoother, quieter, and no ackerman effect.

Overall, I vastly prefer the PSS’s for their better grip, handling, and responsiveness that they give during the hot months.

However, I am extremely grateful to have the new A/S 3+’s to be able to enjoy the car in the cold months. It’s all about having the best of both worlds!
