Your friend can check when the tires were built from markings on the sidewall. Tirerack.com has good info on trailer tires. I wonder if your friend had checked the tire pressure before he started? 55 lbs is about the minimum for a trailer tire and that is rated at 55 mph.
Trailer tires wear out in time, not miles.
