Power King Towmax tires for hybrid travel trailer

I went through 2 sets of Promax's in 5 years, then changed brands, others have had decent luck so it's a******shoot. Mine were probably at max load though so take it for what it's worth. I like the wider footprint of my Maxxis, my local auto tire guy ordered them for me after trying to talk me into Carlisle's. If I'd have had the option of Goodyears I'd have gone that route.
