I second that recommendation. I have both PSS and AS3+, and I'd be perfectly happy with the AS3+ as my only tire, year-round for street use. The differences in performance are essentially imperceptible on the street. The PSS can only demonstrate it's superior grip in track use at high tire temps.
GM puts max performance summer tires on Corvettes only because high-performance car purchasers have come to expect them. However, they are absolute overkill on the street, and they have a lot of disadvantages. They just aren't as good below 60ºF. Today's UHP all-seasons, such as the AS3+ have pretty much closed the performance gap for street use.
Temps here are now in the 50-60º range, and I already feel the loss of traction on the PSS. It's time to go back to my AS3+ set, which provide incredible grip down to the single digits.
What all season run flat tires do you recommend for my 2017 Z51 Stingray? I want to replace my summer only run flats.
AFAIK, the only A/S runflats available for your car are the Michelin AS3+ ZP. Like Foosh, we have the original PSS on one set of wheels and the AS3+ (ours are ZP) on another set, switch out each Fall & Spring. Since I do some autocrossing, the AS would not be the best choice for me in summer but if the overnight temps will be below 40', it's time to switch.
The Michelin AS are available both as runflats and as non-runflats, be sure to get the proper ones.
Enjoy!
Just ordered a set for my 2017 Z51 (down to 3/32 all around after 25k miles on the OEM tires)
Pilot Sport A/S 3+ ZP
This is what I went with. I wasn't originally going to go with ZP tires, but decided to after thinking of all the miles I'll be racking up. I didn't want to always have that thought in my mind about what to do if I get a flat.

Question is, do you lose out at all during the summer months if you go with the AS3+ ZP vs the original PSS?
Nothing unless you track your car or are pushing very hard on the street.
You gain no more scrubbing on low speed sharp turns and a huge reduction in the amount of stones thrown up on your car over the stock tires.

Well, if you didn't lose anything at all then the cars would come with the AS as standard.
So yes, you lose something. But as taz and others have pointed out, the loss is only at the top edge of the envelope. If you are driving hard enough on the street that you need the extra grip of the PSS on a regular basis, you are being stupid.
For the autocross and occasional track day, the PSS are best for me.
On the street, I like the extra grip of the PSS in case I misjudge a curve and it turns out to be tighter than I expected. But in 20k miles of street driving in the C7, I haven't yet needed that extra margin and hope to never need it. The downside is that on cooler days (I'll say below about 60'F), you need to get a few miles on the PSS and warm them up to avoid unpleasant surprises.
Each winter we take a long road trip to the South or Southwest. The AS are good for getting out of the Chicago area, though I can (and have) done that on the summer tires by careful route/weather selection. After the first couple of days we seldom see temps below 50' and sometimes up to 90'. But the trip is much more relaxing when we know that we can handle any temperature and up to a couple inches of snow if that happens. Here's a pic of our C6 caught in an unforecast snow storm in central Illinois, January. It was close, but we made it out of the unplowed parking lot and onto the semi-plowed/frozen street to continue southward. These tires were Goodyear AS, but you get the idea.
EDIT: Weather Mode won't do miracles, but it gives the stability system/TC/ABS their best shot at keeping things under control. If there's any doubt in my mind, regardless of which tires are on the car, I use it.
Probably 90% of Corvette drivers would be better served by the AS.
Hope this helps...

In many parts of the US for a large part of the year it's more often the other way around. You don't have the grip on the PSS that you could have with the AS3+. The PSS is only superior to the AS3+ in very hot temps when pushing hard, and the AS3+ is superior all the time below about 70 degrees.

I wish I had the same luck with mileage. I am 5/32 after 14k miles. Check air pressure regularly and don't drive it hard. (well most of the time)
I am looking at getting same tire. I am not a winter driver but hoping these will last a little longer.
Also hoping for a quieter ride. I drive on chip seal roads and it is so noisy in car can hardly hear radio....
already been in the low 30s and loving the difference. No loss of traction due to cold temps. Which I’m VERY happy about cause I’m driving the dragons on the 6th.
If you see a black C7...that’s me.
Get the AS3+. You won’t regret it. Less $$ then the Super sports too.
Please educate me - besides run flat vs non-run flat - Im looking at the specs and it seems that non ZP tire has a different dimension than the ZP (Rim Width Range and Measuring Rim Width) - does the non-ZP fit our Z51's?
Yes they fit. Another option are the Conti DWS-06. Another great tire. I have had both the AS3’s and the Conti’s and actually prefers the Conti’s in the winter months.
