With a gross trailer weight of 1500 lbs., 13" rims, legal highway speeds, routine inspection for damage, moderate ambient temperature, proper inflation and the careful avoidance of potholes and curbs, I'd expect that a new tire with a service rating a notch higher than the expected usage would be very reliable.

The people that tell horror stories about multiple trailer tire failures must be doing something wrong... old tires, excessive load, excessive speed, road hazard abuse, overheating, under-inflation etc..

What is the best bet on a new set of trailer tires?
