It hurts to replace tires that look like new, but....
Just buy new tires every five years.
Rubber rots.
All tire manufacturers advise replacing tires at five years.
Much cheaper than new fenders and possibly a new trailer.
Trailer wreck stories are endless and epic.
Sadly most are true and were preventable.

Michelin does not recommend replacing tires every 5 years, but does recommend it
be done by 10 years; in fact, I'm not aware of any that do recommend 5 year
replacement. Some may recommend that some types of tires be replaced in 5 years,
but I not aware of any. Even so, replacing them every 5 is reasonable, I think,
for people putting thousands of miles on their trailer every year.

The epic trailer wrecks I can recall were caused by the trailer becoming unstable.
I have no idea how many were caused by tire failure.
