We don't currently carry Dynatrail tires so I wasn't able to track down the speed rating on a 205/75R15 unit. There should hopefully be a speed rating listed on the tire's sidewall - most likely with a letter designation. If you don't see any speed rating then it likely has a 65 mph limit, which is the standard.

If you're looking for something that can handle higher highway speeds I highly recommend the Provider ST205/75R15 Radial Trailer Tire - Load Range D, Item # TR20515D, which features an 81 mph rating. I have attached a short video review on this tire that you can check out as well.

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 ST175/80D13 like…

Answer 6

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…

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

Answer 8

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for…
