Question:

Replacement hubs for 1-3/8 straight spindles? My trailer is fairly lightweight but has a 1-3/8 inch straight spindles. The hubs seem to be 5x5.5 bolt pattern, with 6.90-9 rims+tires. Im looking for a spare and not sure if I can find a matching rim+tire combo. Alternately I could replace the hubs if possible so that a more standard rim size would fit. Can you recommend any options? Thanks

It sounds like you may have an agricultural hub and we do not carry any hubs that fit a spindle that is 1.375" in diameter all the way around. In order to be sure about the exact hub you need, the best option is to take apart your current hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them.

The other option is to replace your axle to more easily find compatible parts. In order to choose the correct replacement axle for your trailer you will need to know the dimensions of your current axle's hub face to hub face and spring center to spring center as in the diagram I have added; the other thing you need to know is the weight capacity of the axle you need, which should match or exceed the GVWR of your trailer.

You do have another option, the Timbren Axle-Less Suspension System, which are simply bolted or welded so you do not have to worry about finding an axle that meets any specific measurements such as the Timbren Axle-Less Trailer Suspension System # A35RS545.

I've added a link to our selection of axles for you to check out.
