Trailer tire Load Range is a way to organize tires by weight capacity. The higher the Load Range the higher the weight capacity will be. The actual capacities varies by tire size though so it's hard to be more specific than that unless you had a tire size in mind.

For example the # AM1ST77 that you referenced is a Load Range D and has a capacity of 1,610 lbs at 65 psi. This is the highest Load Range option we have in this tire size of ST175/80R13 but a Load Range C in this size has capacity of 1,360 lbs.

The bias ply tires and radial tires in size 175/80-13 in a load range D are going to have the same capacity: 1,610 pounds at 65 psi. The radial is #AM10210 and the bias is #AM1ST77. You will want to match or exceed the trailer capacity and I do not…

When the option is available, I always recommend going with a radial tire versus a bias-ply. The ride quality will be noticeably smoother and more stable. Radial tires do a better job shedding heat, and since excessive heat is the number one reason…

The 5 on 5 or 5 on 4-1/2 you're seeing on wheels is the bolt pattern. The first number is the amount of bolt holes and the second number indicates the spacing. When you have an even number of holes you can just measure from the center of one bolt…

Answer 8

The difference between the letter D in your ST175/80D13 and the R in the tire size of the Wheel and Tire ST175/80R13 part #AM31985 that you referenced is the tire construction. D stands for bias-ply which is a less preferred tire construction,…
