why cant i find any slicks other then the m/h cheater slicks that 30 inches tall on a 16 inch rim. from what i understand a 28 is too short. not much out there for options. what are all of you guys with built motors and all running? i dont really care about the rim size other then it cant be 15"(man that would be nice), but i would like a dot so i can run the street race events they have here. any suggestions?
