What is the biggest tire that will fit a 250 Yamaha Bear Tracker without it rubbing? Their stock tires are AT22x7-10 trail wolf tires on the front and AT22x10-10 trail wolf tires on the back. The tires are needing to be replaced and I was hoping to figure out what is the biggest tires I can fit on my Yamaha Bear Tracker without them rubbing the fenders and stuff. I am hoping to be able to get 25" tires or so in order to increase my ground clearance. If I can't fit them on the front but can fit them on the back, what size should I get for the front? I am tires of getting stuck in mud from gettin high centered. Also, if someone could tell me the lug pattern on a Yamaha Bear tracker's wheels and what type of four wheelers that I can buy the tires and rims off of to increase ground clearance, I would greatly appreciate it.
