Location: Lake Elmo, MN | I would NEVER consider buying a passenger car or light truck tire for my trailer....ever ! Granted they indeed are rated for 65mph...so I stay at or below that speed. But for a rig like I run (large Ranger) trailer tires are more reinforced and designed to handle the heavier loads on the sidewalls. Run radial trailer tires...they are widely available.
As for tire life, tires wear out s the rubber compounds start to rot from UV rays and atmospheric decay. Treads on trailer tires rarely wear out but the tires should ALWAYS be replaced at around 5 years max. (I once got 7 years out of some tires, but I was at the absolute outer edge of the limits).
Drive your trailer 65 or under and all will be well. Really no reason ever to go faster. Think of it this way...... on a typical trip where you drive 70mph for 200 miles (versus 65), you only save a half hour.
