I've searched a few forums and two dealerships for info and their giving me conflicting information concerning my bike. I have road tires and would like to purchase off road tires. My question is what rims/tires will work. Some say any WR250/450 and any YZ250/450,, others say the 2006 is different and they will not work.. Others say the bearings and spacers are different.. Since i'll only be dirt riding maybe once a month I really prefer to buy used tires and rims.. Any help would be greatly appreciated.
