Hey i just need some help. I have a TriMoto 175 ported polished and all that junk but i am running 22-11-8 tires on it. I ride all hard pack and grass and am inteseted in putting a set of 18's on it. I know it will probably look stupid but im interested more in proformance then anything else but am willing to sacrafice a little top speed cause shes fast enough anyways. Any help or suggestions would be great. Thanks.
