Just got back from the Dragon and i need a rear tire and i am always looking to get my bike to sit lower so i would like to know if a 190/50 will fit on my xb12s without rubbing the drive belt has anyone used this size and how much taller is a 55 than a 50 size tire. From what i looked up they dont make a 180/50/17 in the pilot power 2ct. Be Well
