Guessing the Tire Type on our TTs

If you're referring to tire pressure monitoring system (TPMS) the newer Audi's rely on the ABS system for rotational input which is computed by the ECU for discrepancies caused by over/under inflation. There are no longer sensors within the tire. After inflating to the proper pressure you reset the system via the MMI. My 2011 A5 had this new system but it may have been around even earlier. There is no need to reset when switching between larger/smaller rims per se, but good practice none the less.

That's correct, no TPMS sensors in the tire itself for quite some time now. "Generation 2 system."

Previously swapped out the summer 19's for A/S 18's but PIA to change them myself, so just keep my 19's on year round with the Michelin Pilot Sport A/S. I've gotten through any kind of weather including snow in PA, and they're terrific wet/dry tires. I do fear for a flat since there's no spare, but I just hate run flats.

The rims are nearly perfect. A scuff on 2 of the wheels, but otherwise, with minimum weekly cleaning, they look new. I did have to replace my tires this winter after hitting a pothole and the Pilot Sport bubbled but no rim damage. It was a good excuse for 4 new tires since the original Pilot Sport A/S's are no longer available. Bought 4 new Pilot Sport A/S 3's which are terrific. Plus, the S4 style 19's are great looking on the roadster.

I badly dented an 18" rim this past Winter in a deep pothole so if it's going to happen it's going to happen. Go with the rims you like.
Don't fear a flat as these days much safer to call roadside assistance than to change yourself on busy highways (this coming from someone who historically has always changed flats myself).
And I too dislike run flats and swear by Michelin.

Rougher/noisier ride but yes quite safety-practical. I have them on my wife's car for that reason.
But think to yourself how few flat tires you've actually had. Very few really over the years in my case and our roads are relatively terrible. The last one I had was from a typical contractor's screw thread nail, but as a slow leak I was still able to get to my tire dealer without incident.
I'll roll the dice with much nicer handling and quieter Michelin summer performance and winter snow tires.
