Maxxis tires do fail as any other tire can.
I had a set of Maxxis on a utility trailer. I run the tires at max rated pressure and the load in the trailer was always way under the tire rating.
One day after refueling I looked at the tires as I was returning from paying for the fuel. I noticed one of the tires appeared to be wet and there was no water of mud puddles around.
When I inspected the tire I found it was coming apart and I could see the steel belts.
I replaced both tires at a local tire shop and had to settle for some chinese tires I had never heard of. (Ironman).
I had the tire shop inspect the other tire and it appeared to be in good condition and both tires still had n=more than half the tread left. I moved that tire to my spare as the spare I had was an old class B tire.
Then a year later the Maxxis I had as a spare came apart while inside the trailer as the spare. See picture.
