i've searched for feedback concerning tires for my second gen. currentley i have metzler front and back with the smaller front than factory. i usally ride two up with 36 in front and 41 in rear however after a 612 mile run to the beach and back the rear tire is cupped very bad and needs to be replaced all though it has pleanty of tread left. maybe i need to run more preasure i dont know,i use a digtal gauge which i think is accurate. any thoughts i'm wide open, thanks:bluesbrother:
