Tires getting louder?

My Pirellis got noisy after 10k miles then at 12.5k I got a flat and just replaced all four with Bridgestones. Two tire stores declined to fix my damaged Pirelli because the puncture was at the junction of the outer edge of the tread and the sidewall where they said a patch wouldn't work due to all the flexing in that area when cornering. And I didn't want to buy another $350 run-flat Pirelli. Mine were worn 4/32 from the new tread depth and 2/32 is the maximum allowable tread depth differential between tires according to Audi. So I couldn't buy just one new tire even if I wanted too. The Bridgestones, 255/50R20 non-runflats, are noticeably smoother and quieter.

Same here. Brought my Q into dealership at 8k for tire noise (Pirelli 20s) and told there was nothing wrong. Again at 10k much worse - dealership ignored me and said just buy new tires. Lived with the noise and now 20k need to buy a set.
the Bridgestone’s fit the 285/45r20s ok? Any issues?

That's a pretty bad attitude. Tire pressure needs to be checked regularly and adjusted and the TPMS needs to be reset. At least once a month, every other week is better, especially if you have temperature swings. Tires naturally lose air. The oxygen molecules escape through small pores in the compound. It's not unusual to lose about 1 psi per 4 weeks. On top of that, every 10F degrees in temperature change is another 1 psi loss or increase. TPMS is there as a last resort to alert you if the pressure is really low. We are talking 20-25% low as required by law, so by the time the TPMS goes off you've been driving around on underinflated tires for a while most likely. That affects your mpg, tire wear, handling and safety. Tires are the most underestimated equipment of a car. It's the only thing between the car and the road. Ever seen tires explode on the highway or the aftermath? That happens when folks drive on underinflated tires. Underinflated tires heat up much more than they should and eventually that can lead to tread separation and blow out. The other day I was driving back from LA and was about to pass this BMW. Just when I was coming up on his side, his rear left tire blew. Tread separated and started rolling towards me. I was able to accelerate to avoid being hit by it. The tread kept rolling behind me and eventually went off the road. Please don't be that guy.
Also I had a steelbelt blow out on a semi next to me once, that scared the poo out of me, I think my window was down too, but I don't remember.

To be clear I visually inspect the tires daily, if it looks low I will do more, but as soon as I do more, I feel like its an endless cycle of never being right. (of course this is probably an artifact of having something wrong to begin with). I do like the passive TPMS more than the active, although when the tire is messed up its kinda moot.

I've never done nitrogen, and you're correct temperature often can and does affect the pressure, but I've also checked them regularly enough to know they can go months at a time through temp changes and be fine, if you're constantly losing pressure you have a problem, (could be the rim/tire or just a bad seal).
I'm definitely more hands off, but I'm not "that guy" either.

I experienced this first hand 2.5 years ago when my oldest son bought his Q50S.. Within two weeks he replaced the runflats with Michelin A/S 3's and the difference in comfort, noise, wet and dry traction was incredible. It made the car so much more enjoyable.
Fortunately his car came with the factory spare and jack kit so it was a no brainer to replace the runflats..
