i have 33" x 14 boggers on my DD and they do get flat spots,and they do smell like hot rubber even after a short trip.but i don't care i love these tires.the flat spots go away alot faster than the 36's on my other truck.the most fun on road is watching people roll their window up when i'm next to them. i like changing things on stuff on my truck all the time,including tires, so i don't worry to much about miles on stuff. and stuff
