Trailer Tire Recommendation to Replace a 215 75R 14 Load Range D  

Karrier ST215/75R14 Radial Trailer Tire #AM10229 is rated for 65 miles per hour. If you want a tire in the same size and load range that has a higher speed rating then I recommend Provider tire #TTWTR21514. It has a speed rating of 81 miles per hour.…

The three radial special trailer (ST) tires we offer in size 215/75-14 can be seen on the linked page. These include the Taskmaster #TTWTRTM2157514D in Load range D, the Provider #TTWTR21514 in Load Range C and the Kenda Karrier #AM10229 also in Load…

As a general rule of thumb, trailer tires should be replaced every 6 to 8 years regardless of wear. Even though an older tire might appear to have plenty of tread left on it, dry rot and cracking can cause tire failure. I attached a link to a help…

I have a co-worker who has patched or plugged trailer tires before without any issues. If the hole is on the sidewall or corner between the tread and sidewall you would not be able to patch it. Patching or plugging a trailer tire is a temporary…

A example of a conventional steel trailer wheel is Dexstar #AM20766. Modular wheels are simply trailer wheels that feature cosmetically-appealing holes rather than spokes or a solid inner surface. A good example of a modular trailer wheel would be…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

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…

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…

Tire designations ST205/75D14 and ST205/75R14 are both for special trailer tires with a 205mm width, 75-percent aspect ratio and that fit a 14-inch wheel. The difference between them is the tire's type of construction. The ST205/75D14 tire is a…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

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…
