I also recommend Hercules all terrain tires. They make a couple good ATs.
Mastercraft makes a good AT.
Those brands are subsidiary companies owned by Cooper, as is Definity.
So all those are cousins with similar attributes.
As far as I know, only Cooper AT3 and Hercules AT2 have silica (sand) in the tread. That improves wet traction, Winter traction, tire wear, and gas mileage (reduced rolling resistance).
