I just put 25" Strikers on mine, Honda place said it absolutely would not work, several ppl also said it wouldn't, put em on anyway, and they work perfect !! They rubbed the black flexible fender extensions just a little but after a couple of miles, they melted and clearanced themselves. Took a pocket knife and cleaned it up a bit, ran it a whole weekend hard, no problems... Don't listen to anyone who tels you it won't work unless they have done it themselves. No lift kit either.. Will do my own later, but it is not necessary. Carlyle Strikers 25x12x9.. Awesome pulling power, it will spin them on moist ground, and traction is unreal for a toy quad. Mine makes believers out of big 4x4's every time I go out. It does require some care to keep it from looping out though !
