Had a set of the Discoverer ST's, wore pretty good. One thing I didn't like was when in the wet, sloppy, snow, They just didn't like that, but good every other scnerio I wa sin. I know the Maxx has a newer tread pattern, so hopefully they are even better.
I also had a set of the new(er) A/T3's. I was very happy with those. They are on the short list for when the beast needs new shoes!
What size wheels do you have? What size tires are you considering? And do you have any type of lift or leveling kit?
