Tire failure is usually caused by a few things. It can be from overloading the trailer, improper tire inflation, and/or exceeding the speed rating for the tire.

You should verify that the tire capacity you have for you trailer is adequate for how much your trailer weighs.

The pressure ran in the tires makes a big difference in longevity too. ST tires should be ran with the full pressure rating stated on the side of the tire, for full load capacity and longevity of the tire. If lower pressures are ran the tire will heat faster and hotter and fail prematurely.

Special trailer tires are usually rated to operate at a maximum speed of 65 mph. If you exceed 65 mph, heat could build up in the tire and cause it to break down and fail. If a tire is rated to run at a higher speed, this information should be listed on the trailer's sidewall.

If you can get me the bolt pattern of your rims, the weight of your trailer, and the size of your tires listed on the sidewall I can make you a tire recommendation. The Lionshead brand has a 2 year roadside program that comes with the tires that you might be interested in too.
