Im looking for new wheels and tires to put on my rzr 900. I was looking at the kanati mongrels but I didn't know what size to get. I don't want to get something too big and take away the bottom end. but I don't want to go to small and take away the top end. The wheels and tire sizes I have been seeing is 26 and 28. what would be the better one for racing worcs or loors?
