Expert Reply: The ST185/80D13 trailer tire will be 10mm wider and the tire will go from 24 inches tall to 24-1/2 inches tall. The ST175/80D13 tire you were looking at is load range D and can bear 1,610 pounds at 65 psi.
Is Load Range D better than C?
The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a C load range in the same size, like # AM1ST76 , the capacity is 1,360 pounds at 50 psi.
What does D rating mean on tires?
The D is the designation for the internal construction of the tire. The D stands for diagonal or bias ply construction. That means the tire body plies inside the tire will crisscross. The maximum load rating on the load range C tire in the ST205/75D15 size is 1,820 lbs at 50 psi.
Which is better load range B or C?
Expert Reply: Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same size but it will not increase the capacity of the trailer.
What is the difference between 175 80D13 and 175 80R13?
Expert Reply: 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, whereas R stands for radial.
What does ST185 80R13 mean?
Expert Reply: Loadstar ST185/80D13 Bias Trailer Tire # AM3S331 is a bias ply construction whereas the 185/80R13 you have is a radial tire construction. The difference is how the plies run inside the tire. You would want to keep the construction type the same on the trailer for best performance and even tire wear.
How much weight can a load range D tire carry?
65 psi Load Range: D Maximum Load: 3,042 lbs. Max.
Which is better radial or bias tires?
“Radials offer lower fuel consumption, better traction and flotation and improved cut resistance in the tread area, and run much cooler than bias.” Better traction, less heat and less rolling resistance all lead to better performance, increased productivity and improved operator comfort.”

What is the difference between ST205 75R14 and ST215 75R14?
The ST215/75R14 tire size is larger in diameter/height by just about 0.6 inches and larger in width by about 0.4 inches when compared to your existing ST205/75R14 tires. The larger size will also have a higher load capacity, as this particular tire features a maximum load of 2,200 pounds at 65 psi.
What is Load Range D on a tire?
A load range D tire has the same load capacity as a load range C tire if it is inflated to 50 psi and will provide the same ride characteristics. Load range D tires only provide more capacity and a harsher ride if they are inflated to the higher-rated design pressure.
