What size hub do I need for my trailer? |

There are a lot of factors to consider when figuring out the perfect size for your trailer. The largest hub you can find is not always going to be the best option and vice versa. Get an expert opinion on what size is right for you with this guide from Trailer Life!

The “trailer hub sizes” are important to consider when buying a trailer. The size of the trailer will be determined by the weight and height of your vehicle.

The number of studs/bolts and the diameter of the ‘bolt circle’ are the initial specifications to decide. The bolt circle diameter on most 4 lug hubs is 4″, whereas the bolt circle diameter on most 5 lug boat trailer hubs is 4 12″. A 5″ bolt circle is prevalent on cargo and utility trailers with 5 lug hubs.

What’s more, how are wheel hubs measured?

Place a tape measure over the exposed wheel hub’s face, which protrudes out from the drum brake assembly’s center. The diameter of the hub is the measurement taken across the front of the hub. Make sure the center of the hub is intersected by your tape measure. Make a note of your measurement.

Aside from the aforementioned, how can I determine the weight of my trailer axle? Look for your axle’s load capacity on the trailer’s VIN plate or sticker, which contains the VIN number. On the same plate or label, the axle’s weight rating should be mentioned. In addition, the axle may have a sticker or plate on it that indicates the axle’s weight capability.

Are all trailer bearings the same size, too?

The inner bearing is bigger than the outer bearing in normal bearings, but they are the same size in parallel bearings. There are sets for 1.5 tonne, 2 tonne, and 3 tonne trailers.

How can I figure out what size trailer brakes I’ll require?

You must measure the depth and breadth of the hub drum on the axle to calculate the size of the brake components you need, as shown in the photo. The most typical size, like the # T4071600-500 you mentioned, is 2-1/4 inch broad.

How can you determine a hub’s bolt pattern?
