Yes, the door jamb values are safe, However, they may be overkill. They are the mandated values which correspond to the maximum load of the vehicle. If you have the full load permitted of passengers and cargo, these would be the proper values to use. Notice the same label shows the full capacity for seating as well as the maximum load weight which go along with those pressures.
OTOH, the max cold pressure stamped in the sidewall is not a value related to operating usage...it is the value which is the max capability of the tire to contain air pressure when cold.
I haven't had a chance to go back into the owner manual, but there may be a listing for ordinary usage (driver...little to no cargo) which is likely in the mid 30s, depending on the aspect ratio of the tire. But, if you find the max setting isn't too harsh and bumpy, it's within safe operating limits.
