Replacement 12 Inch Wheel and Tire for a Harbor Freight/HaulMaster Trailer
Question:
I have a 1000lb Harbor Freight HaulMaster trailer. The wheels are 12 inches, with 4 bolts. I measured the bolt pattern and it doesnt seem to be a 4x4, but rather a 4X3.5. I suspect it might be a metric bolt pattern? How do I order a spare rim/tire combo for this trailer in case of a flat?

Helpful Expert Reply:
When measuring for bolt pattern on an even bolt pattern you would measure from the center of one hole to the center of the hole diagonally across from it. In your picture you started measuring at the 1 inch mark. So if the adjacent measurement is 2-13/16 or 2-7/8 inches on center as it looks in your picture then the diagonal is 4 inches.
For a replacement tire and wheel for your trailer you can use # AM30540. I also recommend a spare tire carrier such as # CE27310G.
