Determining Combined Load Range of Trailer Tires

Question:

So if my camper has four tire do I multiply the load range of 1 tire by four to make sure I’m covered?

Yes, to determine the combined load capacity of your trailer tires you would just multiple the single tire capacity by the total amount of tires.

For example, the Kenda Loadstar ST175/80D13 Bias Trailer Tire # AM1ST77 that you were looking at features a 1,610 pound maximum load at 65 psi. Assuming all four of your camper's tires are filled up to their max 65 psi, this would provide you with a combined tire load capacity of 6,440 pounds.

As long as this meets or exceeds your trailer's GVWR (which refers to the most the trailer can weigh when loaded) you're good to go. I have attached a short video review on this particular tire that you can also check out.
