I've got my flame suit on and I know it's sacrilege , but for a "geographic" reason, meaning I live 3 hours from the nearest Porsche dealer, is there an acceptable zero pressure tire for a TT/TTS ?

 

I haven’t seen one. That said, would it solve your geographic issue? I don’t think run flat tires are designed to make a three hour drive without proper air pressure.

 

I think the low end torque and power of the car make it a non-application.......call tire rack as they may know....

 

There appears to be zero options. I'll call Suncoast to see if their Carrera spare kit will work for me. Living in the middle of a desert has it's disadvantages.

 

Porsche Roadside Assistance will send someone local, at least in most places. And you don’t need to have a flat tire replaced by a dealer. Any reputable shop can handle the tires.

 

Run flats are terrible for performance cars in general, and there are no options for 991 Turbo. But 911 is no different than any other car for tire replacement - just keep a goo kit with you (comes with the car, but you can buy a better one) and keep Porsche concierge number handy - they will pick you up. When my GT3 engine exploded on a racetrack, they sent a tow truck to take me from the racetrack (no charge because it was a warranty issue). I think towing for tire issues is limited, but you can get it to the nearest tire shop, not to the dealer. Practically any tire shop can change Porsche tires. The only challenging thing cam be centerlocks. I solve that by putting my torque wrench in the drunk when I go far from civilization. It was useful once.

 

I agree with the sentiment that run flats are not the way to go here. For the TT/TTS (assuming no centerlocks) you are fine with using a reputable local shop. Where things get super tricky is with centerlocks. I live in fairfield county CT, 50 min from NYC, within 30mins from 3 different Porsche dealerships, and I found almost no "local shops" that had the right torque wrench to be used with the centerlocks when I purchased new tires. I had to go back to the dealership. My assumption is that in an even more rural area (3 hours from the nearest dealership), there isnt going to be any shop nearby with the right equipment

 

I really appreciate and value all the input. I compromised and chose a TT with a 5 lug wheel to avoid the extra "steps" involved in maintenance and use of the centerlocks. Right now, I'm still waiting on a response from Suncoast about their Carrera spare kit. I'm making myself more familiar with Porsche Roadside assistance program and I'll be joining AAA to take advantage of their roadside assistance program. As far as racing is concerned , when I became a grandparent, my "need for speed" diminished, but there is a motorsports track,Chuckwalla Valley, near me, I might consider.

 

No compromise at all!! Im sure you will have a wonderful time with your TT.

 

Re: Run flats in general, I am a former 997.1 TT owner (Turbo build ~750 BHP) that ran air Cup2's but I now own a C7 Z06 (~ 665 BHP) and they come with Mich PSS or Cup2's both in run flats only...and I have tried to find equivalent air tires but they are not available in my sizes. I don't track my car but guys that do and mags/reviewers report the run flat mich's are quite competent and I believe some of world's tire manufacturers/high level race teams are now using run flats in competition as a way to mitigate time to the pits on a punctured tire. As to my Z06, she is a vert and a very fun car but I am hearing the siren call of the P TT cars so will have a TTS car in my garage at some point in the near future....possibly a GT2 RS if I can talk wifey into consolidating our properties. Take care gents.

 

Theoretically, unless you have a catastrophic failure like this, your tire goo and compressor should be enough to save you.

The TPMS would advise if there was a slow leak, and goo would patch that long enough to get you to safety/help.

 

I think spare tires represent a self-fulfilling prophecy. I’ve only had flat tires in cars that had a spare tire. In cars without a spare tire (my 991 and my 997), I’ve never had a flat.

Knocking on wood....

 

I was advised by Porsche tech that the marker indicator on the center lock outer black disc can be torqued to with a 3/4" socket breaker bar and that would get you to the desired torque for the wheel? I guess you would have to keep turning as long as you had the strength to keep getting to that marker line?

 

Yep. Instructions are in the manual for temporary torquing without a torque wrench.

 

I think the bigger issue would be breaking the previous torqued bolt in order to get it off; I use a 600ft/lb 4' bar and I can easily move the car/steering without someone in the drivers holding the wheel and brakes.

They are so cool from a techno-nerdy perspective, but my God they are a pain to manage. I'm just trying to imagine 'temporary torquing' with a 3/4" ratchet...
