I have the Pro Comp MT's and they are loud but ok.  KP has the X-terrains and they work great.  I have head nothing but negative things about the AT's, the guys on SiS call them Pro- Craps.  For a street only tire, they would be ok, but almost every rig in New England runs MT's (except ROCK).  If you plan to use your rig off road, I highly recommend MT's.
