I was 40 miles from home when I spotted the culprit in the right rear PS2 with 1200 miles on it



I knew about punctures near the sidewall, and that a proper repair involves removing the tire from the wheel, then plug and patch

I lost no air getting home, but went down to about 25 psi when I pulled the screw out



I find the goop bottle suspect



and needed some practice in case this happens hundreds of miles from anywhere, so I went for



You lube the reamer



When you feel the tip touch the steel belt, you have gone far enough. The instructions don't say this, just common sense.
Then you insert the plug, with 1/3 on one side of the plug tool, 2/3 on the other.
I may have not reamed enough, because this part took some extra leverage.



After you pull it out, you clip off the protruding piece of plug



You all know where the compressor is



and where to plug it in. Not the 12V power source, or you will blow a fuse.



Fill 'er up



But don't trust the gauge unless it says "Drückmessgerat" and "Made in Germany".



Test drive to verify pressures are holding



So what's your opinion?

1. Drive on another 10K miles or so (street only), till at least both rears are worn, then replace both rears
2. Go to a tire shop and get a proper plug and patch from the inside, then drive on 10K miles
3. Go buy another PS2 and sleep well at night.

I'd watch it for a few hundred miles and see. I've plugged many tires, but never on the Porsche. Once a z-rated tire is plugged, it is no longer rated. But it could hold. If you're planning some 'fun' drives soon, or a even a DE, tire replacement is needed. Otherwise, just be prepared if that beast lets go.

I'd prob replace, but that's one man's opinion.

I have done AXs and DEs with a number of self plugged z-rated tires, I have even run the TX mile with a plugged tire on the TT and it held fine during several near 180mph runs, not to mention I drove on it to TX and back from SD.
If the side wall is not involved you should be fine and I would not replace the tire especially if still new.
just my opinion.

#2, should be fine if you patch it. but part of the security of the patch is that the inside of the tyre is inspected and sealed.

Good job Terry! I wouldn't worry about unless you plan some track use, then I would just have it patched from the inside and go with it. Question, on the reamer do you go all the way thru the steel belt or just until you hit it?

Terry Adams

Just till I hit it. Easy to tell when you make the last 1/8 turn, you can feel the tip begin to grind on the steel.

This begs the question, however: when you plug from the inside, you must have to go through the steel belt first. So when plugging from the outside, why not keep reaming a bit when you hit steel?

Terry, just had a puncture in my right rear PS2 about a half inch from the shoulder. I took it to the PCA-friendly local tire dealer and he said they patch them all the time and that it should be no problem. They patched it and the next weekend I did a 3 day DE. No problems.

TT Surgeon

I've done that a bunch, don't worry about it.

I really need to get one of these kits and practice on an old tire in my garage. Nah, I'm sure I'll just wait until I get a flat out in the middle of nowhere and screw myself and then kick myself in the ***.

carcommander

I have plugged a bunch of tires. It holds fine till you can have it fixed properly. I would have it plug patched from the inside. If I were going to track the car or run it at very high speed then I would replace the tire. 135K and your butt are on the line why skimp over a few hundred dollars? Sometimes a steel belt will cut a plug.

This one couldn't be plugged!
