I have had two sidewall nails in my 2013 991 that required tire replacements (one of which took two weeks). The current one in the GTS is in the tread but the patch is now losing air. There is no hope for the PZero in the Porsche! I am becoming tired of what Porsche calls "quality". There is no such thing!

not sure what the lack of quality is you are referring too here, I doubt there is any tire that would resist a nail regardless of brand, only recourse would be runflats, which Porsche does not use on the 911 thank goodness!

So then is the issue with the quality of the patch? - this is down to the installer that did this, not Porsche IMO.

Back to the OP's question . . . The tires on the 991, 20" wheels are 27" tall. Most of the inflatable spares for the older 911 were 25-26" tall. I would not do it!!!

+1 the handling will be at best "interesting" at worst dangerous.

It's not easy either way. You can get more leverage with the tire off. There's not much clearance with the wheel on the car. The reaming tool requires a bit of effort.

Got it guys! This is my thank you. There are no spare tire replacements for the GTS. My current patch at 3500 MILES is not holding. This is my third in a 991. PORSCHES NEED SPARES.

Each of my cars not only has plug kit / compressor but a piece of chalk to firstly circle the nail/ screw ( for reason that becomes obvious once you pull it out ! ) and mark its tread location relative to the side wall if you have to reposition the car , needle nose plier for removing said foreign body and single edge razor blade to trim the inserted plug

So is there a consensus on the best "fix-a-flat" option that wont damage your TPMS? I hate the idea of calling a flatbed for a simple flat.

Vulcanized rubber tire plug kit.
