Upgrading the 5.3 X 12 Wheels and Tires on a Harbor Freight Haul-Master Super Duty Folding Trailer
Updated 08/18/2025 | Published 11/26/2023
Question:
I have a Harbor Freight Haul-Master Super Duty Folding Trailer with 5.3 x 12 inch tires and a 1720 lb. tow rating. Will the Kenda 5.30-12 Bias Trailer Tire with 12inch White Wheel - 5 on 4-1/2 - Load Range D Item # AM30859 work on this trailer? The pilot diameter is different. The Harbor Freight trailer has something like 2.625 and the AM30859 has a 3.19. Everything else in the specifications seems to match. I just want to know before I order. If not, do you have a wheel/tire combination that will work in load range D?

Expert Reply:
The Kenda 5.30-12 Bias Trailer Tire with 12" White Wheel # AM30859 will fit your Harbor Freight trailer as long as it uses the same 5 on 4-1/2" bolt pattern. The larger pilot hole diameter is not a problem since the wheels are lug centric and center themselves on the wheel studs rather than the pilot hole.
