Expert Reply:

Yes, with trailer tires you do need to always keep the tire inflated to it's max PSI rating to ensure you get the full weight capacity of it and minimize heat build up which might cause premature failure.

So to ensure you get the full weight capacity of the # AM30859 you'd need to inflate it to 105 PSI when cold.

On a single axle using 2 of the Kenda 5.30-12 Bias Trailer Tire with 12 Inch White Wheels, #AM30859, the combined weight carrying capacity of the tires would be 2,500 pounds. You would need to add in the weight of the boat, trailer, and anything on…

Hey Lee, so in general the radial tire construction is preferred over the bias ply. You'll get a more stable ride and generally a little less heat build up. If you will be under the weight and speed capacity of your current tires I think…

The Kenda 5.30-12 Bias Trailer Tire with 12" White Wheel #AM30859 will fit your Harbor Freight trailer as long as it uses the same 5 on 4-1/2" bolt pattern. The larger pilot hole diameter is not a problem since the wheels are lug centric…

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…

The 5 means that the wheel is 5 inches wide from bead to bead (not overall width). The J indicates the design of the wheel bead seat but it is nothing you need to be concerned with as this is the most common shape for all trailer tires. To measure…

I believe you mean Load Range since the Load Ranger was the unsuccessful brother of the Lone Ranger. For any given tire size there can be different load ranges. The different load ranges have different weight capacities. This has to do with the…

Trailer wheel and tires don't really need to be balanced. Some people go ahead and still do it but the benefits are hard to notice and since trailers suspension is pretty harsh the weights typically end up bouncing off. I wouldn't mess with…

Answer 10

Provided that you have enough clearance, changing from your Bias 5.30-12 size tire, like part #AM30859, to a Radial 175/80R13, like part #AM31994, could definitely have its advantages and is a good idea. Bias tires are designed for more of an…

Answer 11

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 12

Due to the age of your 96' Coleman pop up and there being a few different versions it's hard to say exactly what size you have, but we did have a guy with a 97' come tell us he had the tire size 5.30-12 mounted on 5 lug wheels so I'll…
