Hey all, new to this forum. Question about wheels. I have a 2007 fatboy and I'm looking at getting a set of fat spoke wheels like Mammoth or Ridewright sells but none of the manufacturers make stock size for this bike (17" wheel). Can i go with an 18" wheel? if so, what tire size will I have to go with to not have taller tires than stock? Stock front 140/75/17, rear 200/55/17. Thanks in advance for any input.
