So 1st I'll say Chap Moto was outstanding, had the tires at my house in 4 days free shipping. The tires themselves are also great, 1st time I've mounted 6 Ply tires so getting the bead to seat was tricky other than that installation was a breeze since I have access to a tire changer.
Tread pattern is great, my test was removing some fabric silt fence from some ditches around my property that were half buried in the dirt and mud, my buddies 500 with tire tread that looked like my old ones kept spinning out. My new tires dug right in whether on grass or gravel (bit soft on road shoulder). I was able to pull about 75' at a shot before losing leverage & momentum. On top of that they ride much smoother than my old Carlisle AT489s. I feel more stability at higher speeds (grass, gravel & dirt). I'll be trying them out in the mud a little once we get enough rain to make the creek on my property nice and soupy.
Other thoughts, they are maybe 1/2" shorter than the old ones but look more aggressive overall IMO. Excellent Bighorn 2.0 knockoff at almost half the price! Glad I pulled the trigger instead of nursing along those old tires any longer.
