I'm gonna go by a tire store today and get some prices I really like the look of those Toyo Tuff Dutys and they have about 2/32" more tread than the BFG A/T plus they are supposedly engineered for diesel trucks that tow/haul. I've always had good service from BFG tires on previous vehicles but i dont really need that agressive of a tread pattern even though its not that rough this my first dually so I figured I would ask and shop around. Definitely gonna consider the Toyos now.
Gbopp, I found the date codes on my Hankooks they are 0709 so that means they were built February 2009 which makes them 5.5 years old. So after all I guess that aint too bad considering there age. The sidewall splitting just showed up on the inner duals a few months ago
