Question:
We are refurbishing an old homemade tilt trailer. We have measured the hub diameter which is 10 inch with a bolt pattern of 4.5. Do you have a hub with my bolt pattern and what would be the part number? The current tire size is 600.16. We would like to get a larger rim size and tire to make the tire and rim 28 inches. any suggestions? Thank you.

Hi Gary; measuring the diameter of the hub won't determine what fits your spindle/axle. You will have to identify your bearings to find the right replacement. They may be stamped into the bearings so start by checking there. If you can't find the part number, measure the inside diameter of the bearings or the spindle where the bearings ride using a digital caliper # PTW80157. See the diagram below. If you can provide me with this information I can see if a replacement is available.

Hey Gary, were you able to check the bearings or measure the spindle with the digital caliper? Once you have those sizes, I can help confirm which hub will fit your trailer. Let me know what you find so we can narrow it down.
