There isn't a specific hub that will work with the Karrier ST175/80R13 Radial Trailer Tire with 13" Galvanized Wheel - 5 on 4-1/2 # AM31994, though you will need one that has the same 5 on 4-1/2 bolt pattern. I can tell you how to determine the correct hub, as you'll need a bit of information.

First, you need to know the weight rating of your axle, and also what bearings your current hub has. You will need 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.

If you are unable to find them, you need to use digital caliper and measure your spindle to the thousandths of an inch where the bearings and grease seal ride. You can use the photo I've attached to see exactly where you need to measure.

For example, the Dexter Trailer Idler Hub # AKIHUB-545-35-G-EZ-K is for 3,500 lb axles, uses inner bearing L68149 (1.378" inner diameter), outer bearing L44649 (1.063" inner diameter) and a grease seal with a 1.719" inner diameter.

If you get back to me with this information I'd be happy to try and help you find the correct hub; I have also added a link below to our entire selection of hubs with a 5 on 4-1/2 bolt pattern for you to come back to, and a link to a video review of the Kenda Tire & Wheel # AM31994.
