PSI in the tire is roughly the same as the PSI on the pavement. If you take load off the truck the patch of tire on the ground reduces proportionally so PSI stays roughly the same. (there is some minor variation as the sidewalls of the tire will hold a small bit of load but not a lot. Also the tread pattern plays in a bit but no a lot).
You have difficulty visually seeing the area of the tire patch on the ground but it is changing.
Having done pavement design in a former life, if you are only getting 29psi of strength, you got sold garbage.
