Not sure, but I believe Michelin is phasing the "old school" MPSS non-runflats out in favor of the new 4S . I found some good date codes on ebay and paid less than $1,000 per set. 295/30/19 front, 325/25/20 rear. I bought 2 extra sets thinking that they might wear out faster than the 30K miles. They didn't. I still have a set left so I'm good for at least another year. You can score a set from Simple Tire using a Befrugal link through and 5% coupon code (pops up when you visit the site) to net down to $1,085 for me. Not bad, but I'd bet you could do better on ebay. Just remember to ask for the date code.

Bill, I didn't have any issues, other than the SC2's have cold weather cracking and traction issues and the PSS ZP's have extremely short tread life, i.e. 8 - 10K miles. Those are fairly vetted norms on the forum. The questions are really:
1) Can you live without run-flats? Some can't so no need to read further.
2) Would you like a tire that doesn't have temperature constraints for performance like the SC2's?
3) Would you like a tire that has 3 times the tread life of the SC2's and ZP's?
4) Would you like a tire that costs 40 to 60% less than those tires above?
5) Would you like a tire with a much more compliant sidewall that rides better and won't bend your rims?
If so, give the Michelin Pilot Supersport non-run-flats in 295/30/19F 325/25/20R fitment for around $1,050 a try.

I just don't find any issues with the tires that come on the cars stock. I had Cup2s on mine and even used them for several track days but when they wore down close to 2/32 I knew they wouldn't be as good in the rain as they were when brand new (they were excellent when new) so I purchased some used PSS ZPs off a forum member and sold the Cup2s to a friend who got a fair amount of track miles out of them. The PSS ZPs are great in the rain and I drive around in temps as low as 25 degrees with no traction issues. However, I never had issues with any of the run flats that came on my 97 C5 or the 08 Z06. Even those GY EMTs would run 75-80 mph through a pouring rain with minimal tread.

Yes, you can patch a run flat. They're not different than any other tire in that regard. They just don't get flat from loss of air pressure because of the super stiff sidewalls, which is what people hate about them.

@Toddiesel Makes sense. Was curious as I've never kept them on my cars long enough to know. Also, I thought you were running R888R's on your daily driver?

Get a Viair pump and a mushroom type plug kit. I carried that set in my 96 GS that had spare tire delete. After getting tired of listening to and putting up with the stiff ride of the Goodyear runflats, I went to conventional GY tires and never looked back. Only carried the pump and plug kit when I left town. Used it once on the way back from Natl Corvette Museum. Worked great to get me home then went to local tire shop and had proper repair done.

I'm a Cup 2 fan for the track mostly because of the run flat ability. At Watkins Glen as with many other tracks with high speed turns there may be a higher chance of safety if a tire gets a cut and goes down. I get 11 to 12 track days out of a lightly used set and find traction is very good almost to the cords even. I think this is because we have done a lot of tire temp and alignment testing on them. Non run flat Super Sports are my street and wet track tire of choice. They are only a few tenths off on the track from a good set of Cup's.

I have read through so many tire threads and still have no idea what tire to try. The sizes never match the stock tire exactly. The stock z07 tires are so bad that a professional driver would struggle to beat a 4 second 0-60 run in it. My Hellcat hooks up all day long better than my Z06, always has. I am not a tire expert, I am not sure what going with a close size would do to the ride and handling. It would be great to find a non-run flat alternative for Z07 fitments, but it is so confusing. Anyone have any definitive suggestions for stock sizes?

There are a lot of different opinions. I have a 2016 Z06/07 that I use as a daily driver summer and winter in Kentucky. In the summer I am running extreme contact continentals and I love them. I do have a pump and repair kit because they are non-runflat. I believe they work much better than the Michelin super sport. I think the runflat Michelin super sport bend the Rims and are very dangerous when temperatures get around 40 Degrees. This time of year I run Pirelli Sotos zeroes and they are great in the winter with snow. Next year I will probably get the Michelin Alpines because they are the exact replacement size. But for three seasons I use the continental extreme contacts and I believe they work for me much better then the Michelin super sports. I have three sets of tires all mounted on rims and I alternate them but I rarely ever use the Michelin super sports. If I was headed to the track I would throw those on as long as the weather was going to be hot. But as a daily driver I prefer the continentals.

I almost bought the non-runflat PSS's from Discount Tire but Im afraid of the cracking some people say that happens on cold weather. I will sometimes take it out of the garage in winter, and dont want my $1000+ tires to get destroyed. I hear the PS4s wont crack because its a better compound.
Im glad to know the non-runflats in 325/25 are wider then the ZP 335's. They will look much better then my Continentals which look wayyyy too stretched.

I, personally, never ran PSS non run flats so i can't comment on that but the PSS's are the worst. And i'll keep sounding like a broken record on that.
If i had to do it again, i'll go conti again lol

Well Greg, I can tell you that since I got the R888Rs, I'm head over heels. They're AMAZING. I really can't break them loose even with traction control off. I mean, I'm sure I could with a high rev clutch dump, but being in first, rolling and using the throttle as an on/off switch, it just GOES. No slipping at all

I have stock sized wheels- 20x12R 19x10F. They do come in stock-ish sizes. I'm running 325/30/20R and 295/30/19F with no issues

I was thinking of going with MPSS 275/30/19 and 325/25/20

Your quoting the aspect ratio. That's not how aspect ratio works on tires. Just like the 325 non-runflats are 1/2" wider than the 335 ZP's. You're thinking 30 must be taller than 25 and 335 is wider than 325. That's just not the way tire sizing works. Crazy....I know. And for the record I would not put less tread width under the front of your Z06. That's not going to help the way it handles. With the switch to MPSS non-runflats in 295/30 and 325/25, I added a 1/2" of tread width front and rear. Feels great.
