has any body used?

i've seen people run them in mud drags out this way and they work great in the mud, i've seen people swap back and worth on the same quad just to prove this argument and they do work in the mud, before i get yelled at, no they won't last as long, blah blah who cares if you winning a comp, i've seen them do well in deep snow as well, seems like anytime is easier to scoop that to find grip they're gonna work good
