I am currently running Toyo M/T's, 285-75/16. I have put 36k miles on them so far and easily have over 5k left. I rotate ervery 4k and keep the pressures unloaded 55psi front and 45psi rear. Great traction, definitely some noise, but it's hard to find a MT that's not loud. They are heavy, makes for a not so fun rotation when each tire/wheel is over 70 lbs. I have no complaints, but I will try something else when the time comes. I just like trying out new stuff.
