Be carefull that you are buying the correct off set wheel. The offset is measured from the ground to the to the bottom of the pilot hole with out a tire on them( the part that will face the hub down). There have been several different offsets and pilot hole sizes sense the 60's to present. The offset deep the tire sits inside the fender and therefore what it will and wont rub on, IE, calipers, steering componants, frame, ect
