I'd take a very strong look at the Mickey Thompson (Baja Atz Plus radail) they rock in my opion!
There a 10 ply true truck tire , very quite on the highway an with aggressive deep AT tread.U run min.of 50 psi.cold in them,they run very very smooth an nice on the highway.
I really do not think there is another tire out there that dose what these tires do. alot of people around here use them on there snowplowing truck because of there great traction on snow an ice along with there long tread life!
Truly a great AT tire these tires are so quite on the highway all i here is the wind noise going down the road.
go to there web site an take a look at them u wont be dissapionted!
