You can find the maximum pressure for the tire ... right on the sidewall of the tire.
I run my tires.. any tires.. at the highest pressure possible before it starts to feel too rough riding.
Unless there is a maximum load in the vehicle when the tires should be pumped to the max...it usually comes down to anywhere from 2-5 pounds below the Maximum pressure stated on the side of the tire.
Experiment a bit.
The only thing you should Not do is run them too low.

With your sidewall being 40% of your treadwidth, you could run as low as 35psi. I would keep it closer to 40psi for rim protection. 35 series runs between 45psi and 50psi

I run 45 on 24s.
