I have tried searching but results are not very good... so maybe we can put this in one place.
I am trying to figure out what pressures are yeilding the best results.
I understand that on a track you dial in your pressure by the percent of pressure increase once the tires are hot, or ideally by measuring the tire temperatures. On the street they never/rarely really get hot though. So what are you finding works best.

I am running 34psi currently 99% normal street use.

34 also. If I go much higher or lower I get that annoying TPMS light.

Totally depends on the tire...

Stock tires...run the suggested tire pressures in the manual...or in Canada and USA..look on the drivers door panel for tire pressures

Usually 32-36 is the norm
