The tire included with tire and wheel combo # AM3S120 is rated for 65 miles per hour. If you need something rated higher what I recommend is wheel # AM20222DX and 175/80-13 load range C tire # TTWTRTM1758013C. This tire is rated for 81 miles per hour. A local tire shop could mount the tire on the wheel. I have linked videos on the tire and wheel for you.

Answer 1

It looks like you may have meant to type the tire size ST175/80-13. Which for a spare tire and rim you would want the part #AM31985 if you have a 5 lug wheel on your trailer currently or part #AM3S120 for if you have a 4 lug wheel.

The difference in the overall diameters of the two tire sizes you listed is big enough that I would not recommend the use of a 5.3-12 tire in place of a ST175/80D13. The 5.3-12 will be 21.9 inches overall, whereas the ST175/80D13 measures 24.1…

Tire sizes that start with the letter P are for passenger vehicles and should not be used on a trailer. That is also why you can't find the exact same size since that is not a common trailer tire size. Your best option is going to be to replace…

Going to a larger wheel and tire won't hurt or affect your axle in any way. So if you wanted to go up to a 13 inch wheel and tire size like the 175/80-13 like with the part #AM31985 for a 5 lug wheel or part #AM3S120 for a 4 lug you'd gain…

The speed rating of the tire you use will dictate the top speed at which you can pull the trailer on the highway, not necessarily the diameter of the wheels you use. If you were to go with a 12 inch tire with a higher speed rating like the Kenda…

Answer 11

The wheel of the Loadstar #AM3S120 that you referenced will fit on the HaulMaster 66771 trailer that you have now. The problem you'd have though is that this is a much taller setup since it's a 13 inch wheel instead of what you have now that…

Most of the differences in the tire/wheel combinations you were looking at come down to the wheel. Out of the available options I recommend going with the #AM3S120 as the tire it comes with is rated to 81 MPH which'll be perfect for highway…
