well, my g/f's dad was looking at my tires and said i needed new ones (i do). he said he could get some buckshot mudders (285's) mounted and balanced with lifetime rotation and balancing for 440 total "for farm use." has anyone had any experience with these tires? they look good imo but i was wandering the tread life on these tires. he has them on both his trucks now and runs over plenty of mesquite trees and they haven't went flat yet, but im just unsure about the tread life. thanks in advance.
