I have a 07 Grizzly 450 and am still running the stock wheels/tires. In the next couple years this wheeler will be brought out to my buddies hunting cabin to live out all of it's glory hauling moose, sheep and cabin accessories. I am looking for a good all around tire, there is definetely mud but most of the riding is on hard packed trail with steep slick inclines, basically a little bit of everything. This being a fly in only place I do not want to be constantly sending tires out there so am looking for the best tire that will hold up and also get through some mud. I am liking the Maxxis Bighorns which appear to be durable and somewhat aggressive? Looking forward to hearing your thoughts and suggestions.
