Those are the best pressures for the street. More air then the recommended will make the ride rougher. Less air then stock you run the risk of loosing a rim or tire on the street (at least around where I'm at)

On track I tend to go out with 26psi cold and warm them up gradually (first through braking then by zigzagging). After a couple of laps at 90% I then drop them such that I can drive them hot at 29 to 30 psi.

On modern street tires, flatspotting from extended storage is way over-blown, easily avoided, and reversible upon a good heat cycle.

True, Sometimes when I leave my daily driver at the airport (outdoors) for a week or so I can feel how the tires are not round anymore when I start to drive home, when I'm home the tires are OK (20 minutes drive).

To 50 lbs??? That is unnecessary. I usually just add an additional 5 to 8 lbs. and I lose very little in the Chicago cold for 10 weeks. After 6 weeks try to catch one decent day to take around block to rotate the tires but I bet if I left it there for 3 months would have no dead spots.

Thanks. And yes, certainly here in the mega-potholed unrepaired streets of Maryland (where your taxes go to corruption and fraud, and zero infrastructure), I often think I'll lose half an axle...
