Update:
I put the Falken ATs to some off-road tasks the past couple of weeks. They put on some miles in fields (recently picked corn fields), and then through the edges of fields that were immediately disced. There were also a couple of steep bluff sidehills up old logging “roads” to get to a neighbor’s food plot.
They seem to perform well in fields and on the steep terrain without losing grip. The road noise isn’t overwhelming despite them being an aggressive tire. I did lose more than a full MPG on average so far, which was to be expected. The biggest con I still see is that these tires can really pick rocks. If you have hard packed gravel roads the tires will fill themselves before depositing them once you are back onto the highway. I cannot tell any noticeable difference between how the truck handles towing (17′ fiberglass boat or 24′ tritoon) with these tires on compared to previous tires.
They seem like great tires for someone who uses a truck as a truck off road in fields, likely mud, or fairly deep snow (I’m guessing). They would not be my first choice if I lived in the suburbs and commuted around town or on the highways only though.
