I have attached a chart for you to take a look at that includes the lug nut torque specifications. If your wheel uses 1/2 inch lug nuts or wheel bolts like the 12 Inch Steel Spoke Trailer Wheel # AM20124 referenced in your question, you will torque them to 75-85 foot pounds.

If you have different size lug nuts, then you will just follow the specifications included in the chart for that size on a 12 inch wheel.

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…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

In most cases 4.80-12 tires that are on wheels with 5 bolts they have a 5 on 4-1/2" bolt pattern. If you measure from the center of one hole to the hole right next to it you should get 2-5/8" if your bolt pattern is 5 on 4-1/2". I have…

The BTR and BT8 denotations refer to the spindle, not the trailer hub. The difference between a BTR and BT8 spindle is that the BTR spindle uses a 1.063" diameter L44649 bearing and the BT8 spindle uses a 0.99" diameter L44643 bearing. In…

That's a good question, and the answer is that your current 5.30-12 tires are not safe for traveling at highway speeds. What you likely have on your trailer now is a bias ply tire, which is not good for highway use because they are stiffer and…

You have compatible hub and brake assemblies selected. The brake assemblies, #23-48 right hand, and #23-47 left hand, will mount to a 4 bolt flange that has bolt holes 2-7/8 inches apart on center. You will need to make sure your existing bearings…

Hey Bruce, it sounds like you might have some older seals, perhaps Transcom seals with the 1.983" OD. We do have one seal, the #10-9 seal, which has proven to be a suitable replacement for these seals. This is a double lip seal with a 1.5"…
