PSS10 Settings Question

How much does this depend on tire construction? Is there much variation across brands and types or do you feel that rule of thumb works regardless of tire?

I've run Bridgestones, Michelins, and Falken. Same rule of thumb for all. The Michelins have the softest sidewall and are much more sensitive to pressure than the others but in my experience were all best in the same ranges. The Bridgestones had the hardest sidewall and least pressure sensitivity but were also the harshest ride.

Oh I've had Pirelli p zeros too and they fell in the middle regarding sidewall stiffness. These were the first generation p zeros. I've heard the new ones are different but not sure how.

This is highly subjective and I'm sure someone will disagree but I prefer soft sidewalls for the street for a softer ride and the ability to change that with tire pressures. For my DE track days I run a stiffer sidewall. Track days get busy and the consistency of the Bridgestone RE11 or RE71 is really nice. I think the stiffer sidewall also works better on track with stock camber settings. Without negative camber soft sidewalls really roll over.

Advanced
I've been experimenting with various PSS10 settings and I had a strange experience today. Recently, I've been running them at 5/6, with my tire pressure at 34/38. I decided to bump up the rear in order to see how it felt, so I stopped mid-drive and changed the settings to 5/7.
The result was interesting. The back of the car felt more solid and controlled in its motions but the front of the car did not do what I expected. I was expecting more grip in front and what I experienced was less. The rear felt more planted and the front felt like it had less traction, wanting to push wide on corners.
What's going on here? I expected the rear to get looser and the front to dig in harder, but the opposite is what happened.
Next I'm going to try upping my front tire pressure 2lbs, so I'll be at 36/38 with the shocks still at 5/7 and then I'll try PSS10 settings of 6/7 and finally back to 5/6.
I assume others have been through this process. Did you have a similar experience?

Remove tire, adjust with spanners, replace tire. Easy day.

been running 6/7 for the last 3 years. goes where i point it, and absorbs bumps pretty nicely.
