Will a 5.30 x 12 Trailer Tire Fit the Same Rim as a 4.80 x 12 Trailer Tire
Updated 09/16/2025 | Published 10/22/2011
Question:
I have a trailer I tow behind my motorcycle, it presently has 4.80x12 inch tires, I have enough clearance and would like to know if a 5.30x12 tire will fit on the same rim, thank you

Yes, a 5.30 x 12 tire will fit the same rim as a 4.80 x 12 tire. Both tire sizes fit on a 4 inch wide rim. There are a couple of things to consider when changing tire sizes. First, the larger 5.30 will be approximately 1.4 inches taller than the 4.80 so you will need to make sure that you have enough clearance above the tire. The 5.30 is also wider by 1/2 an inch so you will need to make sure there is clearance behind the tire as well for the new size.
Also, the capacity of the larger tire is greater. For a 4.80 x 12, B load range, it is 785 pounds at 60 psi. For C load range, it is 990 pounds at 90 psi. For a 5.30 x 12, load range B, it is 840 pounds at 55 psi. For C it is 1,045 pounds at 80 psi, and for range D it is 1,250 pounds at 105 psi.
Adding the larger tires does not increase the capacity of the trailer. Trailer tires should always be inflated to the maximum psi indicated on the tire. I have included a link to our FAQ articles on trailer tires for you. I have also linked our 5.30 x 12 tires.

trailer, auto, and truck tires should never be inflated to the maximum unless carrying the maximum load. Running maximum pressure with 50% maximum load will wear out the center of the tire plus cause more damage on uneven terrain when inflated beyond the load carried. Check it out.
