You've already received a few comments, and here are a few more:
As you lower the inflation pressure...
... the tire's load capacity decreases. To be safe, you'll need to measure the loads the tires are carrying.
... the tire's sidewall becomes less stiff increasing its flexing. That raises tire temps.
... the tire's sidewall is less stiff increasing its flexing. That can contribute to poor handling issues and more being 'pushed' by wind and passing trucks.
... the tire's sidewall is less stiff increasing the possibility that the sidewalls of the rear duals can come in contact, causing a sidewall blowout.
As already stated, it's a huge assumption that the dealer inflated the tires correctly. Some do, but many don't.
