Run flat
Anyone thinking they don’t need run flats should reconsider. Was out on the LIE (famous Long Island expressway) in hov lane hit a massive pothole with my wife’s e. 6 inch tear in sidewall totally shot went to zero psi immediately. Fortunately the Car has run flats and I was able to navigate back to the shop 20 miles back home. Without runflats I would have been sitting on the hov shoulder waiting for a flat bed (and trying not to die). Then dealing with getting home from wherever I dropped off the car.
Anyone who thinks a can of goop and a compressor is a safety net is foolish. This tire would have been a blowout at 70 mph.
The. Decided to take the suv and again try our day trip out East. I now have a stellate growing windscreen ding from a rock tossed by a. Truck. Not sure exactly why I didn’t use the vette for either of these tasks but glad I didn’t. I hear it’s quite an ordeal to replace a windscreen

Run flats these days are so much better than they used to be. It used to be a legit argument to not have run flats for ride comfort and performance reasons, but 99% of people couldn't tell the difference these days. I'll never not have them.

Yes, the old runflats were not the best when it came to ride comfort, handling and road noise. Today's runflats have seen a substantial improvement since then.

Fine advice for the eastern USA and other big metro areas. Out west here it is very possible to be 200 miles or more from anywhere that could deal with any of the recent Corvette tires. There are roads here that the next paved turnoff is 50 miles away onto another paved road that is 70 miles from an Interstate.You end up with a tow and/or 2-3 days stay whether runflat or not until a replacement tire can be shipped in to a location that can deal with our 18/19/20" tires and wheels.

Fix a flat goop is great for knocking your tires off balance.
Spare tires are the worst. They torque factory lugs to 140 ft lbs and you’re expected to use a 10” tire iron to pull them off on the side of the interstate.

A good tire sealer can stop a slow leak, or turn a fast leak into a slow one, and a battery powered compressor will get you back up to normal, letting you drive even further before you need to get the tire properly repaired or replaced. They're not going to solve the OP's problem, but that doesn't mean they're not of value in other cases. If you pick up a screw, leave the screw in, put some sealer in the tire and inflate it, and you're probably good to go until you can get a proper repair done.

I loved the PSS ZPs on C7, and I was also saved from a roadside flat (screw near sidewall) . I had a 2nd set of Michelin AS3+ non-ZPs, which I ran during the cold months, and I felt no difference in noise or ride quality. I only bought those because the ZP version hadn't been produced at that point.
My current Porsche is on non-ZPs because there are no available ZPs in the 20" sizes for that car. Porsche still supplies the pump and goop, and I hope a good ZP choice eventually becomes available.

It's all luck of the draw, paired with where one predominantly drives. I've had the Z06 non-runflats on my C5 for 20 years with nary an incident. But, I've always had RFs on my C7 since the newest RFs are so much better tires to actually drive on day-2-day.
