I believe those tires in the pic are Duelers like the stock tire. Joe Black ran the stock Duelers at Ocala and Uwharrie, and I ran them at Ocala. Ocala had deep mudholes and deep fine sand, and Uwharrie had a lot of mud and some rocky/gravelly terrain, and we did fine with 'em. Some mud tires or good all-around all-terrains will help, but the stock tires do better than you might expect.
