A/T tyres maybe what you're looking for but you may find that you'll find them wanting in some offroad conditions.
M/Ts will be better iin the mud and if you go for the better known names like BFG, Bridgestone, General Grabber then the road noise wont be noticed and the onroad grip is very good for a chunky tyre.
I run General Grabber MT's on the Disco and they are fine. Good on road manners, little noise, not a bad price and very good offroad.
