Trailer tire load rating

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.

Gettin’ close to capacity is...ah...foolish. Weigh the trailer to be sure.

A 4.8-8 is a really small tire, max load on them is under 500lb each (or 250 kg)

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

One tire. A single axle with a tire on each side can carry two tires' worth of weight. (The axle itself might have a higher "weight rating" than the two tires, so go by the lower rating -usually the sum of the two tires is lower than the axle's rating)

Some weight is also on the tongue, so the trailer can carry more, but you have to know all the numbers to not go over what the trailer is supposed to be carrying.

Each tire is rated to 500lbs, so I can carry a max of 1000 lbs?

Somewhere near there. You ought to know what the axle is rated for to not go over that. Your trailer registration might have a weight limit specified there (in BC, a small trailer like that does).

You also have the tongue weight and what your towing ball and hitch can carry/pull as limits.

A 'small boat trailer'

SO trailer will have boat on it .......could be close to axle/tire load ratings with just boat

Remember the axle/tires have to support the boat 'trailer' weight also.

Also, if you hit a pothole, especially at speed, there will be a greater load on the tires than the load just running on a level road. So it is best to have excess load bearing capacity just in case.

Each tire will hold its own stamped max load at its stamped max PSI.
Axle should have some small hard to read tag along the tube with a max weight.
Some weight will also be on the ball of hitch.
Trailer may also have a tag stating max weight.
Keep your speed down, tiny tires spin fast. Check age of tires and bearing condition.
Carry a spare and the tools to change it

take a spare or two,. and the tools to change it, just my opinion,this is not a good idea. them little tires get hot real quick. and just are not meant to carry a load,
