Although a tire might have good tread, one thing to really look at is in between the treads. If there is cracking, it's getting very very close to a replacement time. Dry rot is setting in, which makes the tire not be as flexible, thus a blow out is more likely to happen. It's like dry skin in the winter...it'll crack and bleed.
With the amount of time a trailer can be outside in the summer, dry rot will set in... I'd say with normal use, getting 5 years out of a set would be pretty normal. My old boat (12 years old before I sold it) received it's 3rd set in 2016.
