Any one know where to buy a street tire for the rear and maybe the front on a crf230f (2004). I am not motarding it out, I just want something I could put on there to use on the pavement for wheelies. Also probably the cheaper the better, that works on the stock rim. I just bought the bike and don't have it with me at school so if someone knows what size I need I would also greatly appreciate it. Thanks in advance for any help.
