I bought a boat/trailer last year. The tires were at 30psi. Yesterday I
read the sidewall, and it says that capacity is 575 pounds with the tires
inflated to 60psi!

The boat is about 500 pounds. Any idea what my pressure should be? I only
take it 15 miles twice a year. Thanks.

60 psi.

I have a tandem trailer and the tires state their capacity at 50 psi. I
keep them at 50 psi.

Quite likely, its 60 psi. I mean that's what it says on the side wall.
With two tires, you have a safety factor of 100%. Blow them up to
60 and call it good.

Trailer tires are different than car tires , something to do with the car
having shocks so the side walls are different, inflate them to recommended.

Those trailer tires are probably smaller than your vehicle tires...
therefore thay spin faster.
They are probably bias ply rather than radial...which means the sidewalls
don't flex as much.
they should be inflated higher than your vehicle tires so 50-60 psi sounds
about right.
Might be some info here useful to you.
