Truck tires typically come in two load ratings: G and H.
The G-rated trailer tires are specially designed for handling large RVs and trailers. They have a higher weight tire capacity than other tires and can take a variety of terrains. They can handle about 4400 lbs each. Each model tire is a little different.
An H load range tire can handle much more, about 6700 lbs each. Infographic:

Here is a video that explains the load capacity of various load rated tires:
If you overload tires they will wear out faster. If you get tires that are overly strong you will be weighted down because they are heavy. The load range is printed on the side of every tire.
