Tires: New tires for F250 2WD, bridgestone dueler a t, toyo open country a t

Question
I have a 2006 F250, 2WD. I need new tires. I pull a horse trailer and my current tires (Pirelli street tires-I believe) spin in the dirt/mud all the time. What do you recommend that I buy?

Answer
Kim,

 Trail and error in brand applications has taught me that the Toyo Open Country A/T will suit all of your needs.  Another option would be a Bridgestone Dueler A/T.  For application on your F250 I do recommend that use a 10-ply or load range E tire.
