I have the perfect tire for your trailer. For a ST185/80R13 trailer tire with speed rating of 70+ mph, I recommend the Loadstar ST185/80D13 Bias Trailer Tire - Load Range D part # AM1ST79.

The Loadstar is a bias ply tire with a load range up to 1,520 lbs if used on both sides of the trailer in addition to an M speed rating capable of speeds up to 81 mph. They also come equipped with a 2 year warranty.

I have attached a video review of this tire for your viewing.

The closest tire size we offer to the ST180/70R13 tires on your trailer is the ST175/80R13 which will be about 3/4" taller than your current tires, and just under 1/2" narrower. I recommend the Karrier ST175/80R13 Radial Trailer Tire with…

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…

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…
