ST Maxx wears like a MT, weighs like a MT (has the same carcass as the STT Pro) and sounds like a MT after 30k miles, but it does not handle like a MT. I ran the ST Maxx (255/85R16) under the 100 for +40k miles and currently have a set under my Jeep TJ. It's a decent tire, but its certainly not an AT.Most certainly not an MT. Not even close lol.
