Can the Michelin PSII run-flat tires that come on the 427's, Z06 and ZR1 Corvettes be patched or plugged? If so, can they be repaired more than once? Will such a repair void the manufacturer's warrantee on these performance tires? Any insight here will be much appreciated.
They can be however some shops won't want to patch it for you if they know you've driven on them flat. When driven flat the sidewalls can become compromised thus losing their purpose as a runflat. I had one patched on my BMW and it didn't leak all the way until the wheel was destroyed by a pothole.

Yes, I had my Michelin PS2 ZP's repaired. The repair is a plug/patch fix which eliminates the chance of moisture entering the tire structure. However, like any tire, puncture location and tire condition may deny a repair.

I run Bridgestone RFs, but the shops tell me that Michelin has the same ratings, so here is my free advice
Most places that know how to properly handle corvette run flats will patch a tire up to 2 times, but the puncture(s) cannot be "close" or on the sidewall of the tire.
I've also read that IF patched properly (meaning with the internal large mushroom style patch), that the speed rating is not affected. And Discount Tire plugged them and the warranty was not affected.
I've personally driven (and so have other corvette friends) mine with patched tires on high speed Daytona Speedway HDPE events, and was not been able to detect any issues.
Meaning, the tire pressure did not vary, the tire temps did not vary, and the tread wear did not vary (from the identical unpatched tire). The handling was the same too.
Here's a pic of one that I got about 30k miles out of, being replaced at my local Discount tire. I'm pretty sure that spot you see in the center of the worn tire tread is the stem of the mushroom plug that was in it.

Goodyear tires can be repaired once and maintain the speed rating. Your Bridgestone speed rating will be voided if patched.

One of my rear PS2s was repaired by Discount via combo mushroom style plug/patch two or three years ago.

I was personally told by 2 Bridgestone Engineers (when I was attending a Barrett Jackson event), that the speed rating would not be compromised, but I did not get it in writing
I'll contact them back to be sure I'm not spreading internet mis-information, and I'll edit my posts once they respond to me.

Tirerack's website has a "Tire Manufacturers Puncture Repair Recomendations" and it identifies which maintain the speed ratings and how many tmes they can be repaired. Bridgestone is one that is voided.

Thanks for the additional info saplumr and also to AORoads. I'm hoping that what they have on the Tire Rack site is more generic, because I'm gonna be grilling my friend to give me more specifics on the Bridgestone Potenza RE050A Pole Position RF, because that is my specific tire that I have been hammering at speed.
Here is a quote about this particular tire off the tire rack website: "The Potenza RE050A Pole Position RFT (Run Flat Tire) is Bridgestone's Max Performance Summer run-flat tire developed exclusively for the Chevrolet Corvette C6 ZO6. The Potenza RE050A Pole Position RFT is designed to combine athletic capabilities on the street along with temporary extended mobility for a distance of 50 miles at up to 50 mph even in the event a puncture allows complete air pressure loss."
Actually it gets even more complicated..... With this tire, they have 3 different warrenty documents, depending on when it was made.
Sooooo, even with a specific tire, depending on what year it was made can even make a difference, on repair advice. Because I personally use it, I will try to find out if over the production life of this particular tire, what the consequences are for plugging it (meaning, effect on speed rating, number of times, etc.), and if it has ever changed.
And, I'm sure it could vary with different brands too.....
"...Actually it gets even more complicated..... With this tire, they have 3 different warrenty documents, depending on when it was made. ..."
And that sentence above tells me something (I am guessing tho) that Bridgestone continues to make the same "tire model" but has made running changes in some part of its construction which affects the warranty, probably from a certain time/serial number forward. Not unlike running changes made in car manufacturing during a model year.
It's also interesting to me that Bridgestone says "only if 15 psi is maintained." Not sure how they tell that unless below 15 psi, the tire starts to shred or some such visible difference from say, 16 psi.
Can Run Flat Tires be plugged ?
