I would replace all of them. The tire shop tells me 6 years is about tops for dependability of tires, regardless of the tread,,,,,especially for trailer tires that carry a load. But I swear my dad has 20 year old tires on his trailers. No way he will ever buy a new trailer tire. He just finds another out of the scrap pile at the tire shop if he has a blow out.
What is on that trailer?
I rememberreading once that trailer tire aren't held to the same standards as truck /car tires. I have an uncle that ended up putting some E rated highway truck tires on his bobcat trailer and swears it pulls better than ever.
