In my opinion big tires suck on sport quads. I think the 22's on my warrior are too big, they're too heavy and cornering sucks because of the sidewall flex. Same thing with taller or heavier tires on any other sport quad I rode, they make it feel like a utility quad.
im not sure of the quality but i know i had thought about mudsharks at one time. you can get them in a 21" for sure and i think ive seen them in a 20x12-9, so if you just want something agressive and not tall they may be something to look into
I have 22's on my warrior and I love them for the wet trails. They have insane traction just about anywhere and they sidewalls don't flex as much as you would think. I feel just as good going fast on my mudlites as I do on my 20" Klaws. I have ridden mine for quite awhile now and they show almost no wear. Probably because I ride really soft trails. I reccomend them!
