You need to use square U-Bolts with having a square axle tube. Trying to use round U-Bolts you risk damaging both the bolts and the axle as it creates pressure points rather than distributing the load across the surface. We have a few different size bolts you can see in the list below.

1-1/2" U-Bolts # SP01-120
1-3/4" U-Bolt # 175130
2" U-Bolts # SP01-160

Hi Jim; a tire like the Kenda 4.80-12 Bias Trailer Tire #AM30630 you were looking at is only 0.2" wider than your typical 4.80/4.00-8 tire so that should still be enough inside clearance. The recommended clearance on top is 3" so at…
