Air Pressure on 12X4.80 Trailer tire

[tripleb]

I have a Magic boat trailer, which, with the boat and motor, probably weighs around 500 lbs. The tires on it are 12 X 4.80 and the sidewalls do not have a recommended pressure. They do have a rating of 750 lbs. at 60 psi. and they are load B range tires. So what is the recommended tire pressure for this type of tire? Is it 60 lbs. or something less?

Thanks.

It's 60. If you want it to ride a little better instead of bouncing you might run them between 30 and 60 depends on your springs and load.

Keep them at 60 lb. If you run with less pressure they heat up and the blow out.
