Expert Reply:

Any given tire size can come in various weight load ranges, and sometimes a specific tire size may be offered in different speed ratings too.

In the size 5.70-8 we have tires and wheel/tire items in Load Ranges B, C and D, which mean per-tire weight ratings of 715-lbs, 910-lbs and 1075-lbs respectively. On the linked page you can see all such products. Note that the wheel/tire items are offered in a choice of two wheel bolt patterns, 4-on-4 and 5-on-4-1/2.

For example, part # AM30155 is a 5-on-4-1/2 wheel with a Load Range D tire; this item can handle up to 910-lbs. The wheel is rated slightly lower than the tire and that is why the overall rating is limited to the wheel's 910-lb capacity rather than the tire's 1075-lb capacity.

To choose the correct load range tires take the trailer GVWR (gross vehicle weight rating) which is the most the trailer can weigh and divide by the number of tires on it. This tells you the minimum weigh rating each tire needs.
