Harbor Freight Trailer Tire 4.80-12 Upgrade Recommendation with Higher Speed Rating

Question:

Hello, I was wondering if there is any confirmed fitment of these tires on this Harbor Freight trailer specifically? Or if there were any alternatives that would definitely fit instead. Planning to drive longer trips and wanted a tire capable of maintaining 65mph if possible. Thanks in advance!

The difference between the 4.80-12 tire size you have now and the size 175/80-13 of the # AM3S130 you referenced is 4 inches overall in diameter and in width 2.2 inches. Judging by your pictures it doesn't look like you quite have the clearance for the larger size but since your reason for wanting to upgrade was to have a higher speed rating your best option would be to switch to the # TT48012C which is the size you have now and has a speed rating of 81 mph. This will for sure fit, has the speed rating you want, and has a 2 year warranty.
