My Towmax tires were fine for a while. I watched them VERY closely because of all the stories I've read here and elsewhere. They held pressure pretty well too.
But then on a trip home from the beach, I saw an abnormality in one of them in the mirror. Luckily we made it home. I couldn't see anything wrong looking at the tire on the trailer, so I dismounted it, and could clearly see I had a broken tread. It was a time bomb.
So I had them all replaced with Maxxis and went up one load range (D to E). I don't worry about the tires much any more, though I do check them frequently and ensure I'm at max sidewall cold pressure.
