Might be, "is no fun," depending where you are stuck! Plug and pump, "may work" for some things like a nail, but useless for a large hole where the stiff runflat sidewalls will get you ~50 miles under 50 mph to a safe location to get a new tire or park the car.
Vettes need to be towed on a flatbed NOT with a tow hook!
The OP's comment about non runflats being quiter, yep- BUT forget the "better traction!" Michelin and GM spent millions developing those tires, hard pressed to find better traction except with drag slicks!
Living in San Diego where he won't be driving often when below ~40F I'd buy nothing but the OEM runflats. And I have driven when 28/30F with no issue (just have to be more careful.)

I once posted a question in C6 General about the actual distances people had driven on a flat runflat. The winner was a guy who drove about 750 miles on a flat, because the tire was already ruined by a huge cut and no replacement immediately available. I did not find anyone who actually had a runflat come apart from driving while flat, though the 750 mile guy said his was getting rather hot & gooey.
A distant second place went to another guy with "only" 300 miles while flat.

Good Morning folks,
I just ordered wheels and tires for my C7. I got Michelin 305/25/ZR20 (97Y) and I just learned that they're not runflats. How safe is this where I have my stock runflats since I bought the car. I was told non-runflats have better traction and is quieter but now the issue is when you get a screw is flat!!! Meaning you're screwed because you have no spare and need to get a tow truck correct me if I'm wrong? I'm disappointed where I wanted the runflat and stick with that rule.
greatly appreciated for any feedback.
Thanks,
Juan

You guys that still think the Michelin runflat produces more noise are living in the past. I have tested and driven both and we can't tell any discernible difference. That is between the A/S Plus ZP and nonZP.
