I recently needed tires for my Yamaha Bear Tracker and couldnt find any. I found a guy who had a Yamaha Big bear and the rims had new tires in them. I bought them off the dude to put on my bear tracker. I got the back to on, but notices the center hole of the Big Bear front wheels were smaller than the center hole of my bear tracker wheels. Bolt pattern is the same. But I didnt realize at that time that the big bears had drums in the front. Like I said, I got the back two wheels on my bear tracker, but the front ones I couldnt, is there any way I can make them fit, like new spindles or somthing?
