Kenda trailer tire # AM10002, which you referenced, has a weight capacity of 590 lbs per tire at 60 psi. With a two wheel trailer your capacity will be 1180 lbs, which is not quite sufficient for the 13000 lbs load you intend to carry.

I would recommend going up to a Load Range C tire, like # AM10004, which has a weight capacity of 745 lbs per tire at 90 psi.

I have attached a demonstration video of this part for you to check out.

If you just wanted to get the tires and not replace the wheels you can use #AM10013. This is a 5.70-8 tire, load range D, with a capacity of 1,075 pounds at 100 psi. Four of these will have a capacity of 4,300 pounds so they can handle the 3500 pound…

Trailer tires rarely last much longer than about 6 years and that is the oldest we recommend a tire be before it is replaced. If you got 18 years of service from a set of car tires (!!!) you got lucky, but it surely is time for new ones, and they…

Answer 6

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Answer 8

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

Answer 9

You can add larger wheels and tires to a trailer as long as you have enough room for the larger size. The main clearance issues we find when putting larger tires and wheels on a trailer is from the top of the tire to the fender and from the inside…

The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…
