I have the nitto nt555r2 radials and they have been great, but I am unsure what psi I should run when driving on the street, I have them cold at 25-26 psi and after warming them they come up to 29 psi, is this good psi for these radials. I know at the drag strip i’m gonna put the psi down to 22 at the strip for grip, but daily driving it off the strip, what is the best psi?

I run those tires....for highway traveling only. They balanced well, were actually round, etc.
However, on a prepped track the best time I have gotten with them is 7.60. I get within a tenth of that in black key mode. 19 psi was best for me.
