I've taken the time to mount the inflated donut tire and if it's the front tire that's flat it will fit into the back seat.. I think that if the flat is a rear tire then I'll call AAA to take the tire and wheel to the Porsche dealer and follow them in my car with the spare mounted... I'll do anything rather than be towed...

I can confirm the part of the article about flat-bedding a GT3. Took me an hour to work with the tow truck driver to get the car on. I also had to find my own wood 2x4's (borrowed from truckers) or else we would not have been able to get the car on. It was a complete nightmare!!!

My E39 M5 had the goop system and I was stranded/had to be towed twice with sidewall damage. A particularly annoying experience. While I can say BMW Roadside Assistance did finally find me and tow me to a dealership where I had to return the next day(Damage occured at night) to get a replacement tire mounted, the experience was not desireable. More so then waiting by the side of the road for a tire company truck, but undesireable none the less.
When I got the GT3 I considered the spare. The 996 had one, which I used for a corded tire at the track. I liked that security. I opted to get a 996 spare kit for the 997 when I got the C4. My frunk space is nearly gone and the fit is tight due to the Das Shield on the lid but I can get from the side of the road to somewhere safer!
I considered it worth the money.

I previously posted a pic of a 305/19 in the back seat of my old C4S. It definitely fits in a coupe.

How about saying it like this:
"Can I run the video camera as you attempt to cut off the old tire by slicing thru the thin, not-wire-reinforced sidewall?"
I thought we settled that in the other thread.
Conclusion is at this point nobody knows if it can be done reasonable amount of effort but several of us think it will be easy. There's no steel in sidewalls.
Just a matter of time before somebody tries it and reports back. Either way, no big deal.

My prior post on the emergency spare, including a pic of take off in the back seat area.

Maybe our kits are not aggressive enough - this one has wire to sew the sidewall Plug Kit, and I read where some (off roading) guy used 8 plugs to limp along. I only tried 6 plugs.
I tell you, tenacity is a huge matter of degree.

If you believe that cutting through a tire sidewall is an easy side-of-the-road operation, I think you might be surprised.

Guys who claim it's difficult are speculating.

If I were Bill Gates I'd grab a serrated pocket knife and head for my garage and be back in ten minutes with results. LOL.
If it were kevlar (is it?) yes that's difficult to cut (very weird too) but not THAT difficult (personal experience).
I dunno, soooo darn frustrating not to know!!!

I dunno Mike my guess is you're going to have to prove that. Then I predict your "proof" will have to be speculated upon. I'm just imagining of course. My theory is that surmising does create wonder based upon conjecture; or it that a hypothesis?

If there was any way to put a spare up there in a 997.1 C4 with NAV, I'd love to see it, as I might do the same. Thanks!!

Sidewalls are thin and the body ply they cover is rubber bonded to radial cords of nylon or polyester - maybe kevlar, and a thin leak proof liner is bonded to the inside of that. The "steel" in belted radials is under the tread. The sidewall of my damaged tire felt very soft and thin. Of course this is speculation, but based on reading about radial tire construction to the point that I'm done with that. Only a test will add some weight either way.
