The max pressure is always measured cold. Just like how you usually measure only your cold tire pressure, the max pressure is federally mandated and is a conservative estimate based on the cold pressure. In reality, if the sidewall says 50 psi, they can handle more than 50 psi. The only consideration might be if it's only tested for street use. With the abuse tires take at a track, some might want to play on the safe side of things.

I'm not tracking the car now but if I decide to later I'll lower the pressure a little. For street use it seems to be just right.

I think 40/40 is the way to go

+1 BTW when mounting the tire shop said that sometimes they need to go to 100 psi's for tire to jump on the rim

Oh yeah of course, when mounting tires the pressure generally gets up to 80psi to pop the tires on the rim for a short while, but remember - that is without any weight and the tire is not spinning. An overinflated, 900lbs loaded, fast spinning tire creates icredible forces on the sidewalls.
