This is the emergency tire repair kit that I carry. It includes a 986 aluminum Porsche jack I found on eBay, updated Porsche equivalent tire goop, expanding breaker bar, plug kit and a pair of diagonal cutters to remove the nail and trim off the tire plug. I also carry the Milwaukee tire inflator that is shown on post #11 above and it’s powerful enough that I used it to inflate a flat tire on my truck.

I've bought a Dynaplug kit for my motorcycle and recently another kit for the Porsche. I've never needed to use them but my friend who I recommended Dynaplug to has and it worked for him. There are plenty of YT videos. Of course, tire repair kits cannot repair all tire failures.
I have the ultra-compact Dynaplug Pro in Stainless for the motorcycle (available in Aluminum also)...
And I have the Dynaplug Pro Extreme in Stainless for the Porsche (available in Aluminum also)...
Along with a Porsche jack and a 3/4" extendable breaker bar for the Centerlock nuts in case the shop does not have the facilities.
Hot take: if you go slow enough, almost any low-profile tire with stiff sidewalls can be treated as a very temporary run-flat.
I have driven 20+ miles on a completely flat rear tire, on a day that happened to be very windy. I blamed the wind for the car's squirrelly handling.
Granted this was a Miata, not a Porsche, but same idea. If faced with the necessity of stopping in a "bad neighborhood," I would put on the flashers and limp down the road a bit farther.
I was an instructor for a car control clinic (4 of us shared classroom potion and also were in-car instructors using the track’s retired police cruisers as training cars). We spent time in class talking about tires, winter tires, and specifically if one gets a flat from a simple puncture, you can drive at roughly 20-25 mph to a safe place. If the tire was typical of those on a pickup truck you can probably go much further. The more substantial the tire, the better you’ll do. The centrifugal force spreads the tire out on the rim allowing you to make slow progress. It’s far better than stopping in a dangerous place.
I got this type of flat in my Cayman R only it was worse than a simply puncture. I was driving at night and ran over something in the road that actually took a small ding out of the OEM rim, and put a puncture in the tire too big to be patched. A deer had caught my focus at the moment I came upon the road debris which I never saw (until the next morning when I investigate to see what gave me the flat which was a small piece of sharp concrete broken off of something.. I think I had Cup2 tires at the time. I drove for about 5 more miles to a safe stopping place where I could wait for a flat bed. I had to come to a stop and make a left turn and did so cautiously (worried the tire could slip off the wheel) but I was able to get to safety and an easy spot to load onto a flat bed in a residential area.
As to the OP’s original question, I’ve traveled many thousands of miles in our various Porsches and I normally bring 3 cans of “fresh” fix-a-flat. If it’s anything more complex I’m calling roadside assistance.
Here was my most recent flat in my GT4. The first flat bed to arrive didn’t have proper ramps and we couldn’t load the car (despite my clear description of the car). The second guy was awesome and did a great and careful job. Fortunately I was only 15 minutes from home and my husband was able to bring some tools to pull the metal from the tire. The wheel was fine, just scraped on the inside. I ended up with four new tires because Porsche recommends a difference in tread wear of no more than 30%. I think I had 5k miles and a couple track days at the time so my tires were already at the half way mark.
In this case apparently my right front tire clipped the metal, and stood it up perfectly to pierce the right rear. I didn’t see it as I was approaching an intersection where I didn’t stop (50mph road) but the joining traffic should stop. Someone came screaming down the hill to the stop sign and I was concerned they weren’t going to stop so i was focused on them and not the surface of the road. I learned later there’s a junk yard just up the hill and I now avoid the area, or use extra care when driving through as sometimes stuff falls off trucks going to the junkyard.
Any area where there s a lot of construction especially around hurricane damaged areas is a potential minefield for drywall screws and nails, bits of metal corner mold.
Of all the flat tires that I have had repaired the majority of them were drywall screws I have a packet of $40 screws (some were $100's of $$ new tire)
