If anything, the trailer wheels are probably stronger. There might be some sort of special DOT rating for radial tires on passenger vehicles, but it's been a long time since I studied wheel and tire regulations so I could teach the subject with some sort of correct information.

I had a friend who spent 30+ years working for DOT, but his specialty was writing regulations for pressure vessels like Propane, Oxygen, Acetyline, and similar cylinders used in interstate commerce. He could tell some scary stories about railroad tank cars carrying pressurized gases, etc.
