I have Yokohama Geolander AT+II. I havent had a chance to take them off road yet but lookin at the tread design there pretty agressive for an AT. They also have the same tread bars and are very similiar to the Dueler Revo but costs a lot less 115 a piece, the only problem with this make is that they stoped making them and youd have to find a place that still has some in their warehouse.
Before these I had BFG's and wasnt to thrilled with them, yes they do great in the rocks but if you some sticky snow or mud they're gonna cake up very quickly.
