Time for tires so Maxxis or Goodyear Endurance?

I ran Goodyear ST Marathons on my trailers for over 15 years with never a single problem. For the past 15 or more years, I have been running Maxxis 8008 ST tires and still have never had a single problem. I run my trailer tires at the max pressure as stated on the sidewall.

I think though, if I were still trailering, I would give the new Endurance tires a chance in spite of my good luck with the Maxxis.
