We do have a nice selection of ST175/80D13 trailer tires available that are mounted on a wheel with a 4 on 4 inch bolt pattern. I recommend taking a look at the Kenda Loadstar # AM3S120 that features a maximum load of 1,360 pounds at 50 psi and an excellent speed rating of 81 mph. The bias ply tire is mounted to a steel wheel with an 8-spoke design and a nice white powder coat finish for a sleek appearance and rust resistance.

I have attached a short video review on this tire and wheel combo that you can check out along with a link that will take you directly to our selection of similar combinations you can look through.

No, adding a higher capacity trailer tire does not increase the capacity of the trailer UNLESS the tires you have are rated lower than the axle capacity. A trailers weight capacity is set by the axle so that is what you will be limited to. If you…

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…

Answer 9

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…

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…
