Default What psi do you run

I know what the door panel states. Just want to know if anyone else run different psi for wear, traction and comfort

here is what im running

Front: When I had it at 36psi cold (recommended), both inner and outer edges are worn down significantly more than the center. Usually that means under inflation, since the fronts are not cambered and i rarely do fast cornering. Now im trying it at 39psi cold and will see how the wear goes. Btw usually psi increases by 3 when fully warmed up. It does feel slightly more bouncy.

Rear: at 36 psi the RCF feels like riding on hockey pucks from day 1 under full gas acceleration on 1st and most of 2nd gear. So I lowered it to 31 psi cold and I'm going to up size to 305/30 when the OEM wears out (still at 5/32). The rears are wearing as expected for negative camber. Traction is slightly better, but disappointed for PSS

I dont really care about gas mileage or comfort, or else would got an ES Hybrid

PSS tires are super temp dependent in my experience. Anything below 60ish turns them into rocks. Otherwise they have hooked exceptionally well for me at 30 rear and 34 front.

my oem PSS tires were pretty bad as far as dry traction is concerned. I keep my fronts at 34psi cold you'll laugh at my new rear tire psi because its at 23psi BUT only because im on MT drag radials that warm up to 27psi
