Tire Pressures?
I’ve noticed that 1/2 ton trucks have the same recommended tire pressures front and rear while 3/4 ton and up always have a pressure offset front to rear. Why don’t they run a offset on 1/2 ton trucks...

I have caused undue wear on tires because I overinflated, and underinflated tires. The absolute best way to adjust pressure is by taking the truck ready to roll over a scale that scales each tire... or at least measures both fronts and both backs. Then look at the tire specs and see what pressure you need to carry the load you have.
On vehicles such as the OP has posted about, the tire inflation guidance came from the FMVSS standards the vehicle manufacturer is required to follow and certify. That guidance contains the minimum safety standard for that vehicle's recommended tire inflation for OE tires. To do less than what has been recommended is to violate safety.
Of course, that's an owner's call. Without the built-in load capacity reserves included in the vehicle manufacturer's recommendation, the owner would be relying on zero usage degrading from a used tire.
