Trailer tire load rating

The load rating of a tire, does that mean the one tire can support that weight, or does it mean the axle?

I have a small boat trailer and I plan to go to camp with it loaded with gear inside. I just don't want to wreck the trailer or cause a blowout, etc.

The tire is a 4.80-8

    Load per tire, at a given cold inflation pressure.

    Maximum sidewall pressure equals maximum load

    Since you mention the axle, that has its own rating. You might have tires good for 1400 lbs each but only a 2500 lb axle, for example.
