Patch/plug on tire???
I picked up a screw in my rear pass tire last fall, and had all intentions of getting new rears, but am going to hold off. Are patch/plugs any good? My biggest fear is going fast (100+, well maybe 130+
) and having a blowout. I know it's immature, but I try to hit atleast a 100 everytime I drive the vette, flamesuit on!!
Any experience? Should I do the patch/plug, or spring for new rears?? TIA!!

Theres a combination PLUG/PATCH available. It looks like an umbrella. You insert the plug and the patch in one action. They work GREAT! Unless the hole is in a side wall, you shoild be fine.

I was going to spring for some R888's, but after reading that they only get 3-5k miles, that seems like a bad investment. I really need something that hooks on the street half way decent tho, and my Pilot Sports just don't get the job done!!
Oh, and the hole is right in the middle of the tread pattern.

Here is part of what Michelin publishes;
"A tread area puncture in any Michelin® passenger or light truck tire can be repaired provided that the puncture hole is not more than 1/4” in diameter, not more than one radial cable per casing ply is damaged, and the tire has not been damaged further by the puncturing object or by running underinflated. Tire punctures consistent with these guidelines can be repaired by following the Rubber Manufacturers Association (RMA) recommended repair procedures.
TIRE REPAIRS
Repairs of all tires must be of the combined plug and inside patch type."
Unfortunately this is pretty vague and doesn't cover anything specific for speed rated tires. I've read very detailed instructions for some specific tire that specified the maximum hole that can be fixed and the maximum patch size that can be used to maintain the speed rating of the tire. Michelin doesn't seem to publish this type of specifics but there has to be some limit on the size of the repair before the speed rating is compromized. Still, I would think you are OK if it's a small hole and you use a small patch. Besides, you're not trying to use the full speed rating.

I have a Napa plug gun kit. They are the mushrum self vulcanizing plugs I had 3 plugs in the orig. supercars Never had a problem. A few trips to 120 + Have new tires now & so far no punctures. Knock on wood! 
But I trust these plugs completely.

In all honesty, I guess if they are good up to 180 (i puss out right about there) I'll be good. Isn't the speed rating on zr tires like 215 or something!!

I was driving to a track rental, at one of the meet spots a friend noticed my tire was low. We found a huge flat head wood screw in it. He opened the shop, put a plug in the tire( the tire had less than 1k miles on them). I ran 10-12 passes that day, and ran the tires to about 18k miles. The tire never leaked or gave me any problems at all. If done properly ( not rocket science) you should be fine.

The Z designation is actually an old designation that meant speeds over 149mph. The PS2 have the sevice description (___Y) where the ___ is a load number that varies with each tire size and the Y is the new speed designation that means above 186mph. But, it doesn't specify the maximum speed. I guess it just depends if you're willing to push it to 215mph or not.
I have RE-11's which are only W rated to 168mph...
