Since this tire is 175/80-13 bias tire, tires of this size have weight ratings up to 1,100 to 1,610-lb maximum load at 65 psi.

This information is based on current tires we sell that are the same size like # AM31994. So the rating that I listed is not promised to be accurate, but this information can be used as a guide.

If you are trying to determine the load capacity of the trailer you will need to use the axle to determine that. The easiest way is to look for a plate or sticker somewhere on the axle that provides information such as the part number, lengths, and axle capacity (see picture).

I have a help article attached which shows how to check for the numbers stamped into the bearings. Those numbers will help us figure out the weight capacity of your trailer.
