When I was looking for tires I got to tour a warehouse and pick what I wanted. I ended up with a Bridgestone Dueler A/T they make that and the Revo version which are both one heck of a nice tire.
The 245/75/16 which come stock on 4x4 2500HD's would fit fine on you 2x4. Look alot better than the stock tires ya got now.
